Rib fragments. I am not sure about the jaw. Can I get some close ups on the teeth and some other angles? Also if you want the age, you have to give us some background information on where they were collected. What state? What was the rock like? Were they found in a body of water like a river or lake?
ill upload better pics of the jaw tommorow
they were found alongside the river bed just on the ground as they are
They are not from the states
also as far as i know this part of the world was in water that time, not sure how they got here
