So, I had a Greenops boothi that was missing the the glabella and the entire left portions of the cephalon. @ischua and I dug this fella up at Penn Dixie in the fall. I decided to finally have a go at him to see how much could be salvaged. 

 

Here's the before:

A little more work:

Well done, Jay. 

A shame that 3/4 of the cephalon is missing. :(

Nice job on the prep, though. :)

Thanks, Tim! Although looking at the picture there's more I can do. I need a better micro blaster. Mine won't feed the superfine abrasives and so I have to try and get the tiny details with dental picks. Being a Greenops I was worried about flaking parts off. I'm quickly reaching the limitations of my equipment :/

Thanks guys!

 

Looking at the before picture I took back in November, I'm just now noticing that at some point I lost the left genal spine. That didn't happen in prep, it must've happened at some point while it was either being moved to the new workshop or in the stacks. Just keeps breaking my heart :/

Elaborate please? I am totally open to that possibility, even excited about it. (Starting to seriously question my identification skills though...)

 

I based my initial ID on the longer central pygidial spine. I was under the impression that the Bellas had a less-pronounced version. The Bellas are so rare at the site that at some point I gave up hope on ever finding one and just assumed they were all Greenops.

Thank you so much, Tim!

 

I've been trying to double-down on my trilobite reading, but haven't been super at finding good sources. My main go-tos have been the Grabau publications, which as you said are outdated.

It looks like a good match with some of the Greenops figured in Trilobites of New York.  GerryK can provide additional info.

I seriously don't care if 3/4 of the cephalon is missing. This is a beauty! :drool:
