What is this fossil that looks like crown of thorns

[jmchandler]

This rock is full of interesting fossils. Especially the one on the bottom left that looks like a crown of thorns.

Can anyone identify it or any of the others?

Looks like a graptolite segment to me. They were a form of coral; or at least a similar concept (colony critter).

Looked like an ancient coronavirus to me....Wonder if the cave men wrapped skins around their face in terror.
