evanmistur Posted December 20, 2022 Share Posted December 20, 2022 I found this fossilized vertebra in a riverbed in Fannin County (North Texas) while hunting for fossils from the cretaceous period. My understanding is that the concave/convex ends of the vertebra indicate that it is from a mosasaurus, but I am very new to this so I don't have a lot of faith in my ID skills. If it is a mosasaurus bone, is there any way to determine species? I've read that Tylosaurus and Platecarpus are found in the area, but don't know if there are reliably identifiable differences in their vertebrae structures. Is this a mosasaurus vertebra, and if so, is there any way to determine species? Thanks in advance for your help : ) 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 20, 2022 Share Posted December 20, 2022 I don't think that vertebra are diagnostic to species. 1 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Congratulations on finding a mosasaur vertebra. Mosasaurus is a genus of mosasaur. It's hard to see details in your photos, but it looks like an eroded lumbar vertebrae. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
