What the heck is this?

I don’t know where it was found or how old was it is. 

I found it at one of the cave the mounds sleuthing sites in Dane county Wisconsin, its about 3cm long and looks a bit like coral.

I think that this may be part of a criniod.

@Darktooth then why does it look so weird?

Reminds me of a drum fish jaw without the tooth caps.  Only different.

To us it might look weird but crinoid holdfasts are kinda like roots .. .and I can imagine a world where this could be from that part of the animal.

I'm going to go with a portion of a Halysiocrinus calyx.

I'm in the crinoid holdfast (root system).
