Jeffrey P Posted June 19, 2017 Share Posted June 19, 2017 Very cool find. Congratulations. FOTM, assuming you can ID it? What another fish? Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 19, 2017 Share Posted June 19, 2017 Not sure, ... maybe Pachyrhizodus?

Ptychodus04 Posted June 19, 2017 Share Posted June 19, 2017 @StevenJDennis The vertebrae look more ichthyodectid to me. Could be a small Xiphactinus or a Sauradon. What's the formation? I saw the Eagle Ford Group tag but do you know the formation also? Very nice find!

JarrodB Posted June 19, 2017 Share Posted June 19, 2017 Killer find. Maybe Cimolichthyes. Here's one @Foshunter found. I would enter it in VFOTM. Link to comment Share on other sites More sharing options...
StevenJD Posted June 19, 2017 Author Share Posted June 19, 2017 thanks everyone! This was found in the Britton Formation. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted June 19, 2017 Share Posted June 19, 2017 It is my understanding that Ichthyodectid specimens missing a head can't be definitively identified to a genus due to the fact that all of them had the same body morphology and the differences are in the head. Am I mistaken? One could make a speculative ID based on size but who is to know if you have an adult Gillicus/Sauradon or a juvenile Xiphactinus/Ichthyodectes? Edit: I see the post about Cimolichthyes but IMHO the verts look more ichthyodectid from the pics. Hard to say until it's prepped though.

doushantuo Posted June 19, 2017 Share Posted June 19, 2017 cranial (Forey,2003) Ok ,perhaps lacking in relevance for the problem at hand,but.... Link to comment Share on other sites More sharing options...
doushantuo Posted June 19, 2017 Share Posted June 19, 2017 Ptychodus,I am looking at Patterson /Rosen now. ( long analysis of Ichthyodectid morphology and systematics,from a while back) No direct indications that postcranial material might be totally uninformative,at least in Recent species Link to comment Share on other sites More sharing options...

doushantuo Posted June 19, 2017 Share Posted June 19, 2017 Bear with me,i will post some stuff that could be useful. I'm certainly no expert on the Mesozoic fish of the USA Saurocephalus,Saurodon,Thrissops,Cladocyclus,Proportheus,Ennelichthys,Itaparica,Chirocentrites,Spathodactylys,Ichtyodectes,Xiphactinus, Gillicus,Eubyodectes(Eubiodectes?not sure aboiut the spelling),Coyoo*,Prosaurodon,Vallecillichthys,Inamichthys and another one I'm trying to find out about are the Ichthyodectidae recognized thus far Stewart's 1999 piece on a saurodontid is heavily paywalled,so I know beforehand I don't have everything. I'm looking at a cladogram with absolutely zilch apomorphies concerning caudal osteology. *described from Australia in 1987 edit: straight out of fruitbat's: cavendercaudalichthyodectifOP650.pdf Edit 2: the Patterson i was speedreading is also in Fruitbat's of course.
