Chimpanzee Faces in Stone: Eoliths, Fossil Absence and the Archaeology of Agency
What happens when archaeological evidence appears to contradict the accepted archaeological timeline?
That question is at the heart of two remarkable stone finds presented here.
One is a recently recovered frontal ape-like face in an unidentified, extremely tough grey stone from Hampshire, southern England. It is not ordinary flint or chert and may eventually prove to be geologically unusual or non-local, although that requires proper identification.
The second is a separate gravel find in orange-stained flint, displaying what I interpret as an extraordinarily similar frontal ape subject, together with apparent ochre staining, incised or etched detailing and a complex organisation of facial features.
The significance is not merely that both stones “look like faces”.
The claim is that both independently recovered objects reproduce a highly specific visual subject: a frontal ape or chimpanzee-like face, organised around corresponding eyes, muzzle, mouth, tongue or oral detail, ear and facial structure.
And these are not isolated examples.
Across my wider South Downs assemblage, functional lithic forms and figure stones repeatedly incorporate ape-like heads, faces and composite imagery. Historical eolith collections recorded in antiquarian literature may contain comparable forms from geological contexts reported to extend astonishingly far into antiquity.
This creates a scientific problem that cannot honestly be solved by simply saying:
“The accepted timeline says this should not exist.”
A timeline is a model constructed from evidence.
Evidence is not required to obey the model.
The Same Ape Face Twice
If one ambiguous stone resembles an animal, chance resemblance must be considered.
If independently recovered objects in different raw materials repeatedly organise the same subject using corresponding anatomical features, the question changes.
It is no longer sufficient to ask:
“Can somebody imagine a face in this stone?”
The relevant question becomes:
Why do specific anatomical relationships recur, and what physical processes best explain them?
| Observed Feature | Grey Hampshire Find | Orange Flint Find |
|---|---|---|
| Frontal head composition | Apparent | Apparent |
| Paired eye organisation | Apparent detailing | Apparent detailing |
| Projecting ape-like muzzle | Present in interpretation | Present in interpretation |
| Mouth / oral division | Apparent | Apparent |
| Tongue / internal oral feature | Apparent | Apparent |
| Ear / lateral facial detail | Apparent | Apparent |
| Possible intentional modification | Requires microscopic documentation | Apparent incisions / pigment require analysis |
The point is not to substitute a visual impression for analysis.
The point is that repetition allows analysis.
Repeated form, repeated anatomical placement, repeated modification and repeated association with lithic technology are precisely the kinds of observations that can move a claim beyond an isolated resemblance.
What is particularly striking in comparing these two finds is not simply the shared frontal chimpanzee-like form, but the recurrence of fine details that are not necessary merely to make a stone read as an ape face. In both objects the eye areas appear unusually elaborated. There are possible eyeball forms within the sockets, apparent pupil details, and indications that the eyes may be deliberately crossed or directed inward. On the orange-stained flint pebble this is especially conspicuous: partial or semicircular forms appear to emphasise the pupils, while the right eye also incorporates what appears to be an ochre-etched diamond-shaped element. Such additions go beyond the minimum visual information needed to suggest “chimpanzee”. They imply not crude representation but a surprisingly sophisticated visual language in which individual anatomical features were being manipulated, emphasised and perhaps encoded with additional meaning.
The protruding tongue may belong to the same system. I have observed this feature on other locally recovered figure stones, including at least one further object presenting a strongly ape-like frontal face, and another strong chimp-like, although the tongue motif is not confined exclusively to chimpanzee-like subjects. Its recurrence is therefore important. Eyes, pupils, crossed-eye arrangements, surrounding arcs, geometric eye forms and protruding tongues are not required simply to produce a recognisable ape likeness. Their repeated appearance suggests that these details were carrying information beyond identification of the subject itself. In other words, the maker may not merely have been depicting an ape, but using the ape image as a structured vehicle for additional visual meaning. I believe the wider assemblage provides further clues to how this system operated, and to how such details may have been deliberately employed by Palaeolithic, and potentially much earlier stone-working populations. That possibility deserves to be investigated as a problem in prehistoric cognition and visual communication, rather than dismissed as merely decorative.
The Fossil Record Is Not a Census
One of the most damaging habits in popular accounts of evolution and prehistory is the quiet conversion of:
“We have not found it”
into:
“It was not there.”
These statements are not scientifically equivalent.
Fossilisation is selective. Survival is selective. Geological exposure is selective. Excavation is selective. Recognition is selective.
The fossil record is evidence of presence; absence from it is not, by itself, proof of absence. Yet this elementary distinction is repeatedly violated across archaeology, palaeoanthropology and popular accounts of human evolution, where “no fossil has been found” quietly becomes “it was not there”, or “this was before Homo sapiens” is treated as sufficient reason to dismiss contradictory evidence. That is not rigorous science. It is circular reasoning: the accepted record is used to reject anomalous evidence, and the resulting absence of accepted anomalous evidence is then used to defend the record.
Worse still, potentially important evidence can remain unexamined or be misclassified precisely because the prevailing narrative has already declared its implications impossible. At that point, the model is no longer simply being tested by the evidence; it is being used to decide in advance what is permitted to count as evidence.
This is not an attack on palaeontology. It is basic palaeontological logic, that commonly fails to occur even at professional and graduate level.
The Chimpanzee Fossil Record Proved the Point
In 2005, Sally McBrearty and Nina Jablonski published the first recognised fossil chimpanzee remains in Nature.
The remarkable opening problem of that paper was simple: thousands of hominin fossils were known, yet no fossil chimpanzee had previously been reported.
Chimpanzees obviously existed before 2005.
Finding their first recognised fossils did not create their past existence. It corrected an incomplete record.
The discovery was important precisely because the previous geographical absence of fossil chimpanzees had influenced ideas about chimpanzee and hominin evolutionary history.
Source: McBrearty & Jablonski, “First fossil chimpanzee”, Nature 437 (2005) .
Archaeology Already Accepts Presence Without Human Bones
British archaeology itself demonstrates that skeletal remains are not required before the presence and behaviour of an ancient maker can be recognised.
At Pakefield in Suffolk, flint artefacts from deposits dating to approximately 700,000 years ago were described in Nature as the earliest unequivocal evidence then known for human presence north of the Alps. Yet no human fossil from Pakefield identifies who made them. The artefacts themselves establish the presence of a tool-making population.
Source: Parfitt et al., “The earliest record of human activity in northern Europe”, Nature 438 (2005) .
Happisburgh makes the point even more clearly. Flint artefacts from deposits more than 780,000 years old established the presence of Early Pleistocene hominins in northern Europe, again without the discovery of their skeletal remains. Later, ancient footprints provided direct trace evidence of individuals walking across the landscape.
Sources: Parfitt et al., Nature 466 (2010) ; Ashton et al., PLOS ONE (2014) .
Crucially, the researchers themselves state that there are no Early Pleistocene human fossils from the UK. The footprint makers therefore cannot be identified to species from British skeletal evidence. Homo antecessor is discussed because it is the only known western European hominin species of comparable age and because the estimated body dimensions are compatible with it. That is a comparison and possible attribution, not the identification of the actual Happisburgh population.
This distinction is extremely important.
At Pakefield and Happisburgh, archaeology accepts that somebody was there, that they made tools, occupied a landscape and, at Happisburgh, physically walked across it, even though we do not possess their bones and cannot securely identify the species responsible.
So archaeology already accepts the principle:
NO BONE DOES NOT MEAN NO MAKER.
Material evidence can demonstrate presence independently of skeletal evidence.
The scientifically defensible question must therefore be:
WHAT MATERIAL EVIDENCE OF A MAKER SURVIVES?
This exposes a serious inconsistency whenever anomalous lithic evidence is dismissed merely because the currently accepted fossil record says that a particular species, technology or cognitive capacity was “not there” or “did not yet exist”. The Pakefield and Happisburgh evidence shows that the identity of a maker can remain unknown while their presence and behaviour are nevertheless accepted from the surviving material record.
The artefact comes first. Identification of its maker is a separate question.
That distinction should apply whether the evidence comfortably fits the existing evolutionary timeline or seriously challenges it.
Does a Chimpanzee Image Prove Chimpanzees Lived in Britain?
No, not by itself.
This distinction matters, it's logical to assume they did, but it's not proof.
If these stones are demonstrated to contain intentional representations of a chimpanzee-like ape, they would establish evidence concerning the knowledge, memory, conception or representation of that subject by a maker.
That is not automatically the same thing as proving that a living chimpanzee population occupied Hampshire.
The subject could theoretically derive from direct observation, geographical movement, inherited cultural knowledge, memory, another ape morphology, symbolic convention or some currently unknown source.
Those become secondary research questions.
The first question is simpler:
Is the image intentionally organised?
Rejecting that question because no recognised chimpanzee fossil exists in Britain would be circular reasoning.
The Eolith Problem: A Natural Mechanism Is Not a Universal Diagnosis
The word eolith has acquired extraordinary historical baggage.
The current Wikipedia entry summarises the category by saying that eoliths were once considered artefacts but are “now believed to be geofacts”.
See: Wikipedia: Eolith .
That wording compresses a complicated scientific controversy into something dangerously close to a universal verdict.
There was legitimate scientific work demonstrating that natural forces can fracture flint in ways resembling crude human retouch.
Marcellin Boule discussed experimentally produced eolith-like forms in 1905. Samuel Hazzledine Warren likewise investigated naturally fractured flints and later described a “natural eolith factory”.
Historical source: “On the Origin of Eoliths”, Nature 72 (1905) .
That work established an important proposition:
Nature can produce lithic fractures that resemble elementary human workmanship.
It does not logically establish:
Every object ever called an eolith was therefore produced naturally.
Those are different propositions.
A demonstrated mechanism is not a diagnosis of every specimen.
If a Victorian collector placed ten naturally fractured stones, five genuine artefacts and three uncertain objects into a drawer labelled Eoliths, no experiment demonstrating natural fracture could magically convert every object in that drawer into a geofact.
Each object would still require examination.
If all eoliths can be dismissed as products of nature simply because nature can fracture flint, then the same logic can be used to dismiss accepted stone tools in museums throughout the world. Nature can fracture those too. The question has never been whether nature can break stone; the question is whether the surviving pattern demonstrates intentional working.
In a substantial proportion of the antiquarian eolith assemblages, the evidence goes far beyond isolated fractures. There is design logic, working logic, organised flaking strategy, targeted edge and blade sharpening, repeated exploitation of predictable flint fracture, deliberate-looking modification of particular functional areas, and coherent tool forms. These are precisely the kinds of relationships from which intentional manufacture and cognition are inferred in accepted lithic industries. In some specimens there is an additional layer: apparent ape, animal and other figurative organisation integrated into the tool form itself, exactly as in my discovery from my UK site.
This creates an unavoidable double standard. If organised fracture, selective edge preparation, repeated technological strategy and coherent morphology demonstrate agency in an accepted Palaeolithic assemblage, the same evidence cannot suddenly become meaningless when it occurs in an “eolith” from a geological context measured in millions or tens of millions of years. The workmanship does not cease to exist because its implications are inconvenient.
Calling such assemblages “geofacts” on the basis of age or historical classification is not an explanation of the evidence. It is an avoidance of it. The design logic, fracture strategy and evidence of cognition have to be explained. If nature is claimed as the maker, then nature must account for the complete technological pattern, not merely demonstrate that rocks can break.
The evidence must determine the chronology. The chronology cannot be allowed to determine, in advance, what counts as evidence.
See my Eolith Atlas, and think for yourself.
Anne O'Connor's history of the eolith controversy describes a genuine multidisciplinary dispute involving archaeologists, geologists, professionals and amateurs rather than a simple story of foolish collectors being corrected by obvious science.
Roy Ellen's later historical analysis similarly notes that although the historical eolith debate eventually collapsed, the technical problem of distinguishing artefacts from geofacts remains a current archaeological issue.
Reference: Ellen, “The Eolith Debate, Evolutionist Anthropology and the Oxford Connection Between 1880 and 1940” (2011) .
That is very different from pretending that one early twentieth-century experiment scientifically diagnosed every historical eolith collection on Earth.
When the Narrative Becomes Circular
There is a serious methodological danger when chronology is allowed to police evidence instead of being tested by evidence.
The circular form looks like this:
- The accepted chronology says a particular maker, technology or cognitive ability did not exist at date X.
- An anomalous object apparently contradicts that chronology.
- The object is rejected because the proposed maker, technology or cognition “could not” exist at date X.
- The absence of accepted objects at date X is then cited as confirmation of the original chronology.
That is a self-protecting argument.
It is not good science.
Current evolutionary chronology is a scientific model constructed from fossils, genetics, geology and archaeology. It is enormously informative but it remains a model capable of revision when sufficiently strong evidence requires it.
We know this because revision has happened repeatedly.
Stone Tools Already Broke One “Impossible” Timeline
For decades, stone-tool manufacture was closely associated with the genus Homo.
Then the Lomekwi 3 assemblage in Kenya pushed recognised intentional stone technology back to approximately 3.3 million years ago, predating the earliest currently recognised members of Homo.
Source: Harmand et al., “3.3-million-year-old stone tools from Lomekwi 3”, Nature 521 (2015) .
The evidence changed the timeline.
The timeline did not get to veto the evidence.
Engraving and Cognition Have Also Moved Backwards in Time
A geometric engraving associated with Homo erectus at Trinil, Java, was dated to roughly 380,000–640,000 years ago, dramatically extending discussion of intentional geometric marking beyond the conventional association with recent modern humans.
And in 2024, research in Sulawesi dated the oldest currently widely recognised surviving representational scene to at least 51,200 years ago.
Source: Oktaviana et al., “Narrative cave art in Indonesia by 51,200 years ago”, Nature 631 (2024) .
Again and again, apparently secure boundaries surrounding technology, cognition and art have moved when new material evidence survived scrutiny.
That history should produce intellectual humility, not chronological dogma.
The 10, 20 and 30 Million Year Problem
This is where the eolith question becomes genuinely uncomfortable.
My Eolith & Tertiary Tools Atlas brings together more than 200 historical records involving eoliths, proposed early stone tools, figure stones and related material from classic sites and collections.
Explore the database: Eolith & Tertiary Tools Atlas .
Some historical specimens were reported as recovered in situ from stratified geological deposits assigned to parts of the Miocene, Oligocene, Eocene and other remarkably ancient contexts.
In some cases this means claimed geological ages measured not in hundreds of thousands of years but in tens of millions of years.
That does not mean every such specimen is thereby proven to be a 10, 20 or 30 million year old manufactured tool.
Geological age of a reported deposit and demonstrated age of manufacture are not automatically identical.
Historical provenance must be checked. Reworking must be considered. Old stratigraphic terminology must be translated into modern geology. Original descriptions, plates and collection histories must be reassessed.
But neither should these objects disappear merely because their reported ages are inconvenient.
The scientifically responsible response to extraordinary provenance is:
CHECK IT.
Not:
IGNORE IT BECAUSE IT CANNOT BE TRUE.
Ape Faces in Ancient Tool Forms
The present chimpanzee-like faces matter because they may not be an isolated modern observation.
Across my own assemblage I have repeatedly documented ape-like subjects incorporated into:
- flint tools;
- scrapers and cutting forms;
- figure stones;
- composite or anamorphic objects;
- pigmented and apparently engraved surfaces;
- objects combining utility and imagery.
Comparable ape-like morphology also appears, in my interpretation, among historical specimens recorded in old eolith literature.
This is precisely why the argument cannot be reduced to one photograph and the word pareidolia.
If the same iconographic organisation genuinely recurs across independently recovered material, different raw materials, different collectors and historical collections, then recurrence itself becomes part of the evidence requiring explanation.
Pareidolia Is a Hypothesis, Not an Explanation
Pareidolia exists.
Humans perceive meaningful forms in clouds, rocks, bark, stains and random visual noise.
Therefore any proposed figure stone must survive the possibility of accidental resemblance.
But saying the word pareidolia does not explain a specimen.
It does not identify how a particular scar formed.
It does not explain an incision.
It does not explain pigment.
It does not explain sequencing of removals.
It does not explain repeated placement of particular anatomical features.
And it certainly does not explain a whole assemblage merely by being repeated loudly enough.
“Pareidolia” is an alternative perceptual hypothesis. “Geofact” is a proposed physical diagnosis. Neither word removes the obligation to examine the object.
A critic who proposes natural formation should be able to identify the relevant natural processes and show how those processes account for the complete observed morphology better than intentional modification does.
That is a scientific argument.
Search Engines, Wikipedia and AI Do Not Decide Archaeology
There is a further modern problem.
A simplified statement can now be copied between websites, search results, encyclopedia summaries and machine-generated answers until repetition itself creates the appearance of authority.
But a thousand repetitions of:
“Eoliths are geofacts.”
do not constitute a thousand scientific examinations.
They may ultimately trace back to the same tiny group of historical arguments.
Search ranking is not experimental archaeology. Wikipedia consensus is not microscopy. AI output is not provenance analysis.
If a modern summary says a particular object is naturally fractured, the obvious scientific question remains:
Which object was examined, by whom, by what method, and what observations establish that diagnosis?
Without that chain, a categorical statement risks becoming inherited narrative rather than demonstrated science.
The Hypocrisy That Must Be Avoided
Archaeology correctly accepts stone artefacts as evidence of ancient hominin presence where no human skeleton is available.
It correctly recognises that technological and cognitive chronologies can move when better evidence appears.
It correctly recognises that distinguishing artefacts from naturally fractured stone requires analysis.
Therefore it would be methodological hypocrisy to celebrate lithic evidence when it comfortably extends an accepted chronology, but automatically downgrade lithic evidence to “nature” when its implications become too old or too disruptive.
The standard must remain the same:
Examine the evidence.
Not the comfort of the conclusion.
Why These Finds Matter to Evolution, Art and Cognitive Science
If intentionality can be demonstrated in these objects, their importance extends far beyond the classification of a few stones.
A figurative representation is evidence of more than manual fracture.
It potentially requires a maker capable of:
- recognising a living form as a coherent visual category;
- selecting diagnostic anatomical features;
- holding or recalling a visual concept;
- mapping that concept onto irregular stone;
- using existing natural morphology strategically;
- adding or removing material selectively;
- understanding how another viewer might recognise the result;
- possibly repeating a conventional visual motif.
That concerns visual cognition, memory, abstraction, representation, communication, planning and the externalisation of mental imagery.
If such behaviour can be securely demonstrated at dates substantially earlier than currently accepted figurative traditions, then major accounts of the evolution of art and cognition would require revision.
If comparable intentionally manufactured imagery were ever securely established in genuinely Tertiary contexts, the implications would be vastly larger still.
Extraordinary implications demand extraordinary testing.
They do not justify refusing to test.
A Scientific Programme for Testing These Claims
I am not asking archaeology to accept these objects because I say they are important.
I am asking that the strongest specimens be subjected to the same seriousness routinely applied to discoveries that already fit accepted expectations.
Useful investigation should include:
- Petrological identification of the unusual grey Hampshire stone.
- Geological sourcing to determine whether the material is local or exotic.
- High-resolution microscopy of suspected incisions, percussion scars, abrasion and retouch.
- Fracture sequencing to determine relationships between removals and later surface alteration.
- Residue and pigment analysis where ochre or other colouring material is suspected.
- Patina and weathering comparison across modified and unmodified surfaces.
- 3D surface recording to document morphology independently of lighting and photography.
- Blind comparative assessment of repeated anatomical landmarks across proposed imagery.
- Experimental replication comparing humanly produced marks with plausible geological processes.
- Assemblage-level study rather than cherry-picking isolated objects.
- Historical provenance reassessment of the strongest antiquarian eolith records.
- Modern geological review of claimed stratigraphic ages and possible reworking.
This is where the argument belongs.
Not in ridicule.
Not in authority.
Not in the automatic assertion that something “cannot” exist because a textbook timeline currently has nowhere to put it.
The Challenge
I have spent years documenting an assemblage from one relatively small area of southern England containing an extraordinary quantity of apparently worked stone, tool forms, repeated figurative subjects, pigment, unusual iconography and recurrent visual conventions.
The chimpanzee-like or ape-like subject is only one part of that evidence.
Historical collections and antiquarian literature suggest that the wider problem may extend far beyond my own site.
So here is the challenge:
Do not tell me the object cannot be worked because its implications are too old.
Identify the stone.
Examine the scars.
Analyse the pigment.
Test the provenance.
Compare the repeated forms.
Propose the natural mechanism.
Attempt to falsify intentional agency.
If the evidence fails, demonstrate why.
If it survives, change the narrative.
That is how science is supposed to work.
Conclusion: Evidence Does Not Owe Allegiance to a Timeline
The fossil record is indispensable.
It is not complete.
Archaeological chronology is indispensable.
It is not infallible.
Natural fracture is real.
It does not make every disputed stone a geofact.
Pareidolia is real.
It does not automatically explain repeated structured imagery.
And the word eolith must not be used as a convenient intellectual dustbin into which uncomfortable objects can be thrown without individual examination.
The two chimpanzee-like faces shown here are important not because they instantly prove a complete alternative history of Britain, chimpanzees or human evolution.
They are important because, together with the wider assemblage and historical record, they raise testable questions that the conventional narrative does not presently answer.
Science has no right to demand that evidence remain ordinary.
It only has the right to demand that extraordinary evidence be tested extraordinarily well.
That examination is overdue.
A quick look at what else appears in that Stone.
Here are a few other standard lithic language subjects that can be found in that Gray chimpanzee like face stone:
 |
| The third interpretation is more challenging, but it belongs to another motif that is strongly represented across my wider assemblage: a pterosaur-like profile or partial figure. Look carefully at how the thicker line defines the neck and body. The same geometry can also be read through another recurring convention: reinterpret the apparent wing-tip area as the diamond-shaped fin or flipper of a mosasaur-like marine reptile, and another coherent animal form emerges. That type of deliberate visual switching where the same worked lines, edges and geometric features participate in more than one image is central to what I have been arguing for years. These are not simply pictures imposed on random stones; they appear to use a repeatable visual language in which outline, orientation, shared anatomical features and transformation between subjects were deliberately built into tools and artefacts. |

FAQ
Are these stones proven chimpanzee carvings?
I interpret them as intentionally worked representations of a chimpanzee-like or ape-like frontal face. Their significance lies in the repeated anatomical organisation and apparent modification, but independent microscopic, geological and comparative examination would strengthen or falsify that interpretation.
Does the absence of chimpanzee fossils in Britain prove chimpanzees were never present?
No. Fossil absence alone is not proof of biological absence because fossilisation and discovery are incomplete processes. However, an intentional chimpanzee-like representation would not by itself prove a living chimpanzee population in Britain either; it would first demonstrate knowledge or representation of an ape-like subject.
Why is the first fossil chimpanzee discovery important to this argument?
Until 2005 no recognised fossil chimpanzee had been reported despite thousands of known hominin fossils. The later discovery demonstrates how an empty fossil record can reflect preservation, geography and sampling rather than actual historical non-existence.
Do archaeologists require human bones to prove ancient human presence?
No. Pakefield and Happisburgh in Britain show that stone artefacts, stratigraphy and trace evidence such as footprints can establish hominin presence without a corresponding human skeleton.
Are all eoliths natural geofacts?
Natural processes can unquestionably create eolith-like fractures, and some historical specimens may be natural. But demonstrating a natural mechanism does not scientifically diagnose every individual specimen ever labelled an eolith. Artefact or geofact status must be assessed from the evidence of the particular object and its context. Many historical eoliths look exactly like accepted ancient flint tools.
What is wrong with simply calling an unusual stone pareidolia?
Pareidolia describes the human tendency to perceive familiar forms in ambiguous stimuli. It is a legitimate alternative hypothesis for apparent imagery, but it does not explain physical incisions, pigment, fracture sequence, repeated anatomical placement or assemblage-level recurrence unless those observations are also accounted for.
Are the claimed 10-, 20- or 30-million-year-old eoliths proven artefacts?
No universal claim should be made from geological labels alone. Some historical eoliths were reported from deposits assigned remarkable Tertiary ages, but their provenance, possible reworking, geology and workmanship require modern specimen-level reassessment before a manufacture date can be considered secure. Current evidence suggests they are incredibly ancient stone tools.
Why would ancient figure stones matter to cognitive science?
Intentional representation potentially records visual memory, categorisation, planning, abstraction, communication and the ability to externalise a mental image. Demonstrating such behaviour at unexpectedly early dates would directly affect models of cognitive and artistic evolution.
How can an artefact be distinguished from a geofact?
Useful evidence includes fracture mechanics, percussion features, repeated retouch, technological sequence, microscopic wear, residues, pigment, patination, geological context, refitting, replication experiments and comparison with the wider assemblage. No single visual characteristic should carry the entire interpretation.
What is the Eolith & Tertiary Tools Atlas?
It is a searchable research database at Eoliths.org bringing together more than 80 historical records of eoliths, proposed early stone tools, figure stones and related finds, including links to antiquarian publications, plates, locations and reported geological contexts.
What should happen next with the Hampshire grey stone?
The raw material should first be identified petrologically and compared with local geology. High-resolution microscopy and 3D recording should then document suspected working, while any unusual residues, staining or pigment should be independently analysed.
