A real shark tooth embedded in a limestone boulder!

Stop 4: Shark's Tooth

Black spot on boulder that is Petalodus shark tooth fossil with penny next to it for scale, which is a little smaller than the fossil.

Shark tooth on limestone boulder. This block of limestone has a large tooth of the shark Petalodus. The block is loose and also contains brown nodules of chert, unlike any of the local Permian limestone bedrock. This is evidence that it is actually Pennsylvanian limestone which moved from a different location.
