Fossil Identification

[Dawn544]

Good morning, I'm a new member to the forum and am excited to learn more about some of the things I've found as well as to learn about what other things are out there to fine in my area; We were away for the weekend in the Catskills (Orange County New York); while walking through the woods near Big Pond we found several of items (as pictured) and have no idea what they are.  In the home that we were staying at there were several more of these that had been found y someone else but the homeowner didnt know what they were either.  Anyone that has any knowledge about these would be greatly appreciated.  Thank you!

Neat find. These are similar to Cucullea sp., otherwise nicknamed "deer heart clams."

I agree - internal casts or steinkerns of bivalves.

Very cool find! Also welcome to the forum. Please stick around, we have some very knowledgeable people here and there is always something unique to be found.

I don't think these originated in the catskills. These look like typical Cretaceous or younger Cucullea but the rocks around the catskills are Devonian.

Hello and welcome! I’ve never heard of these “deer heart clams”. Neat finds. Very cool to learn something new! I feel like I do everyday here on TFF.
