Thanks Bill! I actually posted this tooth a while ago, but I was checking something on the upload process and forgot to delete this one.

I think this is a partial snail fossil rather than vertebrae. If you could provide more photos with a scale bar, we can probably narrow down what type of snail.

Looks like a small section of a belemnite.

Hi @james-ellsworth, I saw your message, but I’m unsure why your comment is showing up here. The ‘ears’ are lateral cusplets, which may have served to help grasp prey and/or prevent food from getting trapped between the teeth.

I actually think this is a freshwater snail (Class Gastropoda). There are Neogene sediments in the area you reported your fossil from, so ammonites would be too old. Also, I cannot see any evidence of the characteristic sutures that are present on ammonites.

Hey @jacob-polzin, this does indeed look like a cetacean tooth. It’s difficult to say what kind, given that it’s a partial tooth. The size makes me want to guess something like Eurhinodelphis, but I’m not certain. I know Stephen Godfrey from the Calvert Marine Museum is working on a book describing the cetaceans from the Calvert Cliffs, but I’m…[Read more]

This is from a whale or dolphin, so you can put Cetacea for the order and Mammalia for the class.

Hi @jacob-polzin, I think this one is a croc tooth! The taxonomy of Thecachampsa is heavily debated, but for now we can say it came from the order Crocodilia and the family Gavialidae.

This is a piece of soft-shelled turtle bone, family Trionychidae
