Megalodon Fossil Replica

I borrowed this replica fossil of a C. megalodon shark. The fossil was to be used to show some grade school classes different types of fossils. The topic of dinosaurs and sharks comes up when giving fossil talks so I thought having this to show would give students some idea as to how large these sharks could get. This creature swam around in the Paleogene Period of the Cenozoic Era.
Thanks to Mark for loaning it to me.

Megamyonia Brachiopod

These fossils are Megamyonia sp. found in the Maquoketa Formation of Fayette County, Iowa, USA. They existed in the Late Ordovician Period.

Strophodonta Brachiopod

A Strophodonta brachiopod fossil found in the Milwaukee Formation of Wisconsin. This fossil needs to be cleaned as it has some interesting rings on its surface. This might be some sort of coral colony that was growing there or it could be some scattered crinoid rings.
Thanks to Nathan for this fossil.
