Description
My last piece, portraying several Eugeneodontids! Popular in the media for their weird mouthparts, specially the espiral saw of Helicoprion and the jagged scissors of Edestus, these enigmatic Chondrichthyans lived from the Carboniferous to the Triassic. Despite not being true sharks, they evolved convergently, so their body plan is most likely to have been extremely similar (I've always been obsessed with reconstructing them with a different body, but I've realized that stands no chance for accuracy, and sharks are really cool so who cares).Usually portrayed without pelvic, anal and second dorsal fins due to fossil impressions of Fadenia, it is not a definitive fact since in said fossil only part of the tail is preserved, and the the whole section of the body where those fins would are found is missing, besides, all Chondrichthyans have pelvic fins (anal and second dorsal may or not be present, both options are plausible). The featured genera are Helicoprion and Edestus (of course), Ornithoprion (which I definitely oversized), Fadenia and Caseodus (they are the only reference for soft tissue in Eugeneodontids thus far so they deserve some love), and Sarcoprion (which I completely made up because there are no images of the fossil and I could only look at heavily outdated and inaccurate depictions of it). Enjoy!
