Fossil ID

So.... It's a rock from an abandoned house rock garden. I'm guessing a vacation find because we don't have these around here.  It looks like a claw because the base is flat or straight across. About 3 1/2 cm. I can't offer much info on origin.

Mineral filled cracks in a mineral (calcite?) rich sediment layer. I think the claw is a clast within finer sediment that has weathered some.

I think you have something close to what is known as https://en.m.wikipedia.org/wiki/Speleogen
