Trilo-bit from Milwaukee

[Anomotodon]

Hi everyone! I visited an exposure of the Milwaukee formation within Milwaukee city, Wisconsin this weekend. Found lots of brachiopods, corals and bryozoans, and brought some rocks home. Then today I decided to smack some of them with a hammer - and this trilobite pygidium emerged out of nowhere. I don’t know a lot about inverts - can anyone help with the ID please, if it’s identifiable at all? I’m pretty sure it is from the Lindwurm member of the Milwaukee formation (Givetian - Middle Devonian). Thanks!

Looks like an Eldredgeops I doubt you can narrow it down further then that.
