Chondrichthyian palate

Pucapampella rodrigae

Chondrichthyian palatoquadrate. Not much is known about these fish as fossils aren't too common and preservation isn't great, mostly just impressions from this formation, this species may be synonymous with Zampoponiopteron, another chondrichthyian fossil found in the region but whereas this represents skull elements Zampoponiopteron is fossilized fin material.
