DevonianDigger Posted January 27, 2017 Share Posted January 27, 2017 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: A little more: And, finally: For size: Jay A.

Fossildude19 Posted January 27, 2017 Share Posted January 27, 2017 Well done, Jay. A shame that 3/4 of the cephalon is missing. Nice job on the prep, though.

DevonianDigger Posted January 27, 2017 Author Share Posted January 27, 2017 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 :/ Jay A.

Darktooth Posted January 27, 2017 Share Posted January 27, 2017 Nice prep work! Congratulations! I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
DevonianDigger Posted January 27, 2017 Author Share Posted January 27, 2017 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 :/ Jay A.

fossilcrazy Posted January 28, 2017 Share Posted January 28, 2017 Jay, Your Trilobite appears to be a Bellacartwrightia, a little rarer than a Greenops. Link to comment Share on other sites More sharing options...
DevonianDigger Posted January 28, 2017 Author Share Posted January 28, 2017 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. Jay A.

Fossildude19 Posted January 28, 2017 Share Posted January 28, 2017 Jay, Check out these PDFs. LINK 1 LINK 2 They may help with clearing things up.

DevonianDigger Posted January 28, 2017 Author Share Posted January 28, 2017 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. Jay A.

piranha Posted January 28, 2017 Share Posted January 28, 2017 It looks like a good match with some of the Greenops figured in Trilobites of New York. GerryK can provide additional info. Link to comment Share on other sites More sharing options...
DevonianDigger Posted January 28, 2017 Author Share Posted January 28, 2017 Here are a pair of images, the example of Greenops barberi from Lieberman & Kloc and a similar image of mine. The only thing that doesn't seem to quite match is the fixigena. Jay A.

Fossil-Hound Posted March 25, 2017 Share Posted March 25, 2017 I seriously don't care if 3/4 of the cephalon is missing. This is a beauty! Do or do not. There is no try. - Yoda Link to comment Share on other sites More sharing options...
