This is being sold as a Theropod vertebra. It is from Hell Creek, Carter County Montana. It is 2.25" long x 1.5" wide x 1.25" thick. It has dimensions similar to the vertebra of Dakotaraptor so I am assuming this was from a fairly large animal (Not saying it is Dakotaraptor, just similar in size according to a paper on line). SInce we are looking for my bones for kids to interact with this may not be a bad fossil to get if it is a theropod.
Any thoughts ?
