Trilobite Pygidium?

[hitekmastr]

This is a fossil from our Tully NY trip - is this a trilobite pygidium (tail section)? Would appreciate help confirming this. Thx.

By the way, we're still examining our fossils and finding new and unexpected things. We don't have a lot but what we have is fairly dense and sometimes we find that we focused on one side of a rock with a nice fossil but overlooked the other side which had an even nicer find!

Looks like one to me; one of the savants will probably stop by and put a name to it (and list what it had for lunch).

Looks like the internal cast of a phacopid; Eldredgeops, Phacops, etc...

...for lunch it had brachiopods on the half-shell (see photo 4)

This is great news...we've been collecting 2 months and now have a greenops, dipleura and phanops...that's 3 species out of 15,000...only 14,997 to go!

Since we're on a roll with our trilobites today - here is another trilobite we found, a bit less well defined...

The less well defined pygidum is an Eldredgeops.

Thanks - much appreciated - piece by piece, our species count is slowly moving toward a half dozen.
