wetwilly Posted May 25, 2016 Share Posted May 25, 2016 Hi, Hoping someone can help with an ID on this... Sort of looks Enchodus to me. This fragment is about 3/4" Any ideas? Thanks Bill Link to comment Share on other sites More sharing options...
Darktooth Posted May 25, 2016 Share Posted May 25, 2016 Looks like maybe croc scute frag. But I have been duped on this one before. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 25, 2016 Share Posted May 25, 2016 My first thought was pycnodont mouth plate, minus the teeth? Something like this: What does the other side of it look like? Maybe one of the regulars like Carl will weigh in on it.

wetwilly Posted May 25, 2016 Author Share Posted May 25, 2016 Thanks for the help. Looks like maybe croc scute frag. But I have been duped on this one before. I was thinking that as well , but never actually found one - or did I? Here is the other side Tim. Bill Link to comment Share on other sites More sharing options...
Mike from North Queensland Posted May 25, 2016 Share Posted May 25, 2016 Unsure on ID but the specimen has that fish look to it. Mike Link to comment Share on other sites More sharing options...
wetwilly Posted May 25, 2016 Author Share Posted May 25, 2016 Unsure on ID but the specimen has that fish look to it. Mike Yes, I agree. That's why I was thinking Enchodus - but the circles were telling me croc... Bill Link to comment Share on other sites More sharing options...
caldigger Posted May 25, 2016 Share Posted May 25, 2016 I got my money on the fish jaw. But not Enchodus. More likely of the drum variety. Link to comment Share on other sites More sharing options...
Auspex Posted May 25, 2016 Share Posted May 25, 2016 I got my money on the fish jaw. But not Enchodus. More likely of the drum variety. Yeah, maybe a piece of pharyngial plate?

tmaier Posted May 25, 2016 Share Posted May 25, 2016 I'm with drum mouth plate, sans teeth. Definitely not a scute, I have plenty of those. Link to comment Share on other sites More sharing options...
Carl Posted May 26, 2016 Share Posted May 26, 2016 My first gut reaction was croc osteoderm, but there are clearly things about it that scream against that ID. However, I could definitely see that as a piece of croc skull. I don't see a pycnodont jaw here or other fish part but it is hard to tell. Link to comment Share on other sites More sharing options...

Wow, I was tipping the scales toward drum - now my head is spinning. I will try and look up references to your ID to see if I can find any indicating factors. Thanks Carl.

wetwilly Posted May 27, 2016 Author Share Posted May 27, 2016 Chen/Meyers(Mat.Sc.&Eng.): http://www.meyersgroup.ucsd.edu/papers/journals/Meyers%20381.pdf Thanks for the link, great info! Thanks Tony it is pretty cool even though I'm not sure what it is. I have this alligator skull and the top portion looks similar to what I think Carl is suggesting. Even though we think it's a croc, is this in line of what is suggested? I understand the difficulty on identifying such a small fragment especially when not in hand , but I am curious and want to understand. Thanks!
