Can you identify this? My dad found this in loose rock while stabilizing a limestone cliff in the Finger Lakes area in NY state. We often find mollusks and horn coral (rugosa), but this one is larger. A few inches long and about 2 inches wide.

Also, it's in two pieces - how to best stabilize it so it doesn't get further damage?

It's a trilobite.

Looks like a trilobite for sure. I'll take a stab at Eldredgeops/phacops or greenops, based on the assumption it's a Devonian area?

Wow. We have found a couple of incomplete rolled up ones over the years, but much smaller than this. I have been told the rugose coral we find is Ordovician but I am pretty ignorant.

Here is a geologic map of New York. The Finger L:akes are is almost entirely Devonian.

Dipleura dikayi trilobite. Probably from the hamilton group.
