Mosasaur Humerus?

[msantix]

Hi everyone.

 

I recently bought this Mosasaur fossil that was labeled as a Tylosaurus Humerus, and i just wanted to check if this is indeed a humerus or another part of a mosasaur because looking at some pictures on the internet of mosasaurs (and Tylosaurs) it could also be a radius. It is 5 and a half inches in length and was collected in the Niobrara Formation in the Smoky Hill Chalk (Kansas).

 

Since i am not an expert on mosasaurs (i am still learning about them) and my knowledge is limited, i was hoping someone who knows about mosasaurs could help out in confirming if this does belong to a Tylosaurus and if it is a humerus or a different part. I do trust the seller i just thought it would be worth posting on the forum to see what others think. Any help would be greatly appreciated.

This looks just like the other Tylosaur Humerus fossils I've seen. Size wise it looks good too. I'd say the ID is correct
