Hi everyone, thanks for checking out my post! I found this dude at the beach a few days ago and haven't quite pinned down what it is. It's formed like a bowl, with three lobes and has what appears to be a crinoid in the center on one side. I've found some similar objects under the crinoids and blastoids tab, but they're not quite right. If it is a crinoid, I would very much like to know what part of the animal it represents, a part of the holdfast maybe, or of the calyx?
Found on the beach in SW West Michigan, Berrien County.
aprox. 9mm on one of its three sides, and 4mm high.
I know the first image is really low quality, I'm sorry, I couldn't get it to cooperate. But since there is another from a similar angle and the point of the first is mostly for the ruler, I didn't think it would be too much of an issue.
