Hi!

I stopped at a rock and fossil show earlier today and I picked up these trilobite parts along with a couple other more complete pieces. 

I was wondering if it is at all possible to ID it only with these parts. I’m thinking the large part is an Isotelus pygidium and the separate piece on the right looks like an eye, but I’m no expert. So if any of you have ideas, send ‘em at me!

 

From Canada, Middle Ordovician, from Colborne Quarry in Colborne, Ontario

Definitely Isotelus. Possibly Isotelus gigas judging by location and pygidium, or Isotelus “mafritzae.”

Awesome, thank you so much Kane!

Not gonna lie, I’m pretty proud of myself for being able to get it down to Isotelus- I’m learning! Yay!

You trilo guys amaze me. I have seen how many species are known and you guys are amazing! Of course, knowing the location helps, but still, amazing.

Fossil hunting is easy -- they don't run away when you shoot at them!
