Fossil- Vetebral Body from what?

[Todd Swanlund]

Found in a dry creek bed in central Montana, Phillips County.  Spinous and transverse processes missing, with one articulate surface intact.

Any help appreciated!

Hi Todd,

My best guess would be that it is either an ichthyosaur or dinosaur vertebra, given that the Cretaceous interior seaway cut through Phillips County, Montana.

There is a small museum you could visit/reach out to for more information: https://mtdinotrail.org/phillips-county-museum/

Best,

Victor
