Auspex Posted April 6, 2011 Share Posted April 6, 2011 That seller is very knowledgeable about plants, but I just don't know what to make of this fossil.

Terry Dactyll Posted April 6, 2011 Share Posted April 6, 2011 I think its a 3D preserved Rhizodont type scale that got 'ripped' as the shale parted along a plane of weakness resulting in the scale patternation being displayed in section creating those 'toothlike structures'...

I have come across a few of these in Ohio from a Westphalian D (Carboniferous) site. It is most of a paleoniscoid (primitive actiniopterygian) maxilla. cheers, -PzF Link to comment Share on other sites More sharing options...

I have found 'boney skull plates' that are apparently individual skull bones but none with any ornimentaion on... Is this typically found adjacent to the jaw on this species?... Cheers Steve...
