crf250rsx3 Posted March 21, 2008 Share Posted March 21, 2008 I found these at the bottom of a creek bed. What do you think they are Thanks Link to comment Share on other sites More sharing options...
Boesse Posted March 21, 2008 Share Posted March 21, 2008 Naw, not quite shark vertebrae... some kind of mammal verts, I think. Nice find though!!! Link to comment Share on other sites More sharing options...
Ramo Posted March 21, 2008 Share Posted March 21, 2008 There not shark. They look like pleisiosaur to me. The one on the left looks like the last one before the skull. You should go back and look for that!!! For one species to mourn the death of another is a new thing under the sun. -Aldo Leopold Link to comment Share on other sites More sharing options...

Uncle Siphuncle Posted March 21, 2008 Share Posted March 21, 2008 In Mansfield Texas the Upper Cretaceous Lower Britton formation outcrops. It is known for its marine reptiles including Plesiosaur material. Some lucky folks have found cool stuff like Pterosaur and Pliosaur (Polyptychodon) material in addition to articulated fish skeletons in this formation as well as good shark teeth, fish teeth, etc. The matrix tends to have a yellowish hue that makes it easy to spot in creeks and construction areas. 1 Grüße, Daniel A.

Carl Posted March 21, 2008 Share Posted March 21, 2008 I'd even possibly believe they are simulacra - merely look alikes of non-organic origins. Can you provide close upf of the microstructure of any broken parts? Link to comment Share on other sites More sharing options...
