Ptychodus04 Posted September 17, 2014 Share Posted September 17, 2014 I collected this jumbled up mess of bone fragments at the very bottom of the Kamp Ranch Member, Arcadia Park Formation, Eagle Ford Group in Lewisville, TX. I almost opted out of picking up the bone scraps, small, fragmented, you know how it goes. Then I saw the teeth. I believe it is a juvenile Xiphactinus. I would like to solicit the opinions of the greater collective intelligence on this forum. The files are big (even resized) so... I will post additional pics as replies to this post.

KansasFossilHunter Posted September 17, 2014 Share Posted September 17, 2014 (edited) I'm thinking it could be a partial Saurodon skull. The uniform peg-like teeth are indicative of that fish. I was lucky enough to come across the remains of a baby Xiphactinus last year.

Xiphactinus Posted September 17, 2014 Share Posted September 17, 2014 It's definitely not a Xiphactinus. Their teeth are all different sizes. I don't believe it's a Saurodon -- their teeth are more blade like, and the skull and jaws don't look the correct shape. I think you have an Icthyodectes. It's a fish often confused with Xiphactinus, and other than the skull, there's not a lot to tell them apart. Ichthyodectes teeth are uniform in size, and peg like. http://oceansofkansas.com/FossilFish/vp-1706c.jpg 2 Link to comment Share on other sites More sharing options...
KansasFossilHunter Posted September 17, 2014 Share Posted September 17, 2014 Icthyodectys is related to Xiphactinus but is smaller and with the peg teeth, that could be a candidate. 1 Link to comment Share on other sites More sharing options...
