Pierre shale
Preservation of marine reptile fossils in the Pierre Shale is typically not the best, which means there can be quite some decay from the original form. However, as you're digging marine sediments and the two pieces of bone are obviously procoelous (see diagram below from Wikipedia) mosasaur is the most obvious option. Neural spines frequently ...
