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]
