Here we have the carved and possibly painted image of a water bird. The Swan like bird impression is shown bending its head backwards and cleaning its feathers, this is a well known portable rock art motif, others found in Canada and America. To the left of this flint artwork a face profile of an ape can be seen.
I thought I would share this with you also, this is the piece shown in an earlier post Standing Cloaked Figure. A complete face profile can be seen facing right, could this be an artistic impression of the head and neck of a relative to the Spinosaurus? An ape face profile can also be seen, facing left, just to the left of center.
