Scrappy, worn New Jersey Cretaceous bone

[frankh8147]

Hello all!

 

I was looking through my bone fragments from the Cretaceous of Monmouth County NJ and came across two that I figured deserved one more shot on identification..

 

By any chance, does anyone know of what these may have belonged to?

First one looks like the top of a neural arch from a vertebra but unsure of the animals found in your are.

Plesiosaur and Mosasaur would be the two prime candidates..

The first one does look like a neural process, or even a transverse process. There's a smaller chance it's a rib end. No idea about the second one. From what taxon? Who knows. But reptilian seems a no-brainer.
