Where is it from?

 

Looks like some species of Greenops.

Are those air bubbles I see on the surface? If so, fake. If not, a beautiful specimen.

No. Those would be pustules common on these trilobites.

These are common enough that they wouldn't need to be faked, Mike.  ;)

New York I believe

 

 

Then definitely some form of Greenops.

I'd label it Greenops sp.

 

Maybe @piranha  or @GerryK  could narrow it down more?

Curious, why did you go with widderensis and not boothi? .. I  am trying to learn, is why I  am asking.

The shell color and shale color match perfectly with Greenops widderensis,

 

And I agree With @Kane

  • Enjoyed 1

Cheers!

So what is the difference in the 2? Like I mentioned before, I  am trying to learn.

Take one with the light directly shining on it with little shadow. It looks like a NY Greenops.

I'm wondering if the OP is looking for the morphological basis to identify the species? ID can't be based on location and/or colour.

It will be on the basis of traits unique to the asteropyginae, such as lappet size, glabella shape, and genal spines. Location would be a tell, however, as if it is the case that this specimen was found in Ontario's Arkona area, there is only one species in the Widder (with a variant in the lower Hungry Hollow known as Stummiana arkonensis), but the matrix is not Hungry Hollow. G. boothi was once recorded here in Ontario, but that was back in the Stumm and Wright days. Location -- provenance -- matters a great deal, which is why buying blind is not the wisest practice.

Ask the seller for more details, then. This is not hard. I don't understand this.
