LSCHNELLE Posted November 27, 2017 Share Posted November 27, 2017 Please help my wife ID this possible bone fragment she found. It is symmetrical and it appears to be part of a skeletal bone that broke off at matrix rock's edge. The formation is Eagle Ford Lower Bouldin Flags shell hash layer. Found with small Ptychodus occidentalis and P. decurrens and multiple regular shark's teeth and some other smaller bone frags. Dimensions are 54 mm long by 38 mm tall and 16 mm wide at fracture tapering to ~1 mm wide. It is reportedly in the same layer that a 4" Tylosaurus tooth was found by another collector years ago - which does not match the biostratigraphic record.

ynot Posted November 27, 2017 Share Posted November 27, 2017 Part of a vertebra process, I doubt there is any detail to go beyond that. Darwin said: " Man sprang from monkeys."

Tidgy's Dad Posted November 27, 2017 Share Posted November 27, 2017 Nice bit of bone, but difficult to know from what. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
LSCHNELLE Posted November 27, 2017 Author Share Posted November 27, 2017 Thanks "ynot" & "Tidgy's Dad". We expected as much. You verified it was a vertebra fragment. Last question: What explains two different experts identifying a Tylosaurus tooth from middle Eagle Ford when it supposedly did not exist at that time? Any other similar teeth that could be 4" length with root in early Turonian? See pic. Link to comment Share on other sites More sharing options...

LSCHNELLE Posted November 27, 2017 Author Share Posted November 27, 2017 Any ideas on the tooth that would explain the fossil find? Or, someone who might know the answer? Plesiosaur? Dinosaur? Link to comment Share on other sites More sharing options...

M Harvey Posted November 27, 2017 Share Posted November 27, 2017 The bone looks like a turtle peripheral scute. Can you submit a photo of the bottom side? Link to comment Share on other sites More sharing options...
LSCHNELLE Posted November 27, 2017 Author Share Posted November 27, 2017 Bottom side view shows apparently fractured rock face weathered by rainfall. Here is "bottom" side pic with scale. I gave full dimensions in first post. Link to comment Share on other sites More sharing options...

I have found very similar teeth of the Cenomanian Polyptychodon. Pliosaur teeth usually have massive crowns, very strong striations and no carinae. Also root doesn't look like a mosasaur. Here is a Brachauchenius jaw from the internet. The Tooth Fairy Link to comment Share on other sites More sharing options...
LSCHNELLE Posted November 27, 2017 Author Share Posted November 27, 2017 Looks like a good possibility. Thanks! Link to comment Share on other sites More sharing options...
LSCHNELLE Posted November 28, 2017 Author Share Posted November 28, 2017 The guy who found the tooth admits that he may be remembering the genus name incorrectly. I think the vertebra fragment may be related to the Brachauchenius tooth. We plan to rehunt for the remainder of the vertebra bone to get a better ID. With the right conditions, it may still be present in an adjoining bedrock layer that fractured away from the primary subject ID fossil. Link to comment Share on other sites More sharing options...

It may be doubtful that much more if any of the bone material you found will be recovered. It appears to have some predation damage. It may be very wildly scattered in that event.

We were unable to find any other bone fragments in nearby bedrock or loose boulders. Although, we gave it extra effort. Link to comment Share on other sites More sharing options...
fossilized6s Posted December 4, 2017 Share Posted December 4, 2017 Honestly as rare as it may be, it may be worth while to look into a possible pterosaur skull fragment ("beak" or crest). I would contact Tim Myers at SMU in Dallas just to be sure. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
