Dear Guys,
Last week I was in the coal quarry, Donbass (Ukraine) and found this skin impression in coal shale.
The age is Gzhelian- Early Aselian (Carboniferous and Permian boundary) and judging by the scale texture I can see that scales were very thin (like in the birds and dinosaurs)
so I think it was quite proggressive reptile and it could be the early synapsid. In synapsids scales could be gradually dissapearing like in dinosaurs and birds- they do not look like thick osteoderms.
I tried to find information about Carboniferous reptile skin fossils but I not found anything...
I think it could be very rare find, so please help to identify this if you could
Best Regards
Domas
