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.
