NoahW24 Posted August 29 Share Posted August 29 Last year, while looking around a quarry in Upstate NY (Middle Devonian, Moscow fm), I stumbled across a trilo-bit I have had trouble placing. It’s some kind of phacopid, but not an Eldredgeops, and it just doesn’t feel like a Greenops. Found at a site with associated Dipleura dekayi, Greenops, Eldredgeops, Tornoceras, orthocerid nautiloids. The first photo is the mystery bug in question, followed by a Greenops and an Eldredgeops from the same site for easy side-by-side comparison. The final picture is a close visual analogue I’ve found online, though it is Moroccan and I am unsure of the location of origin. 2 Link to post Share on other sites
Kane Posted August 29 Share Posted August 29 I would wager it is an asteropygine that is exfoliated. I would need to see a top-down dorsal view. 1 1 Link to post Share on other sites
Isotelus2883 Posted August 29 Share Posted August 29 I think it's a bella because of the amount of eye lenses. Link to post Share on other sites

I don't believe that Bellacartwrightia has ever been found at that locality. I think it's a Greenops, but as Kane stated, we need more photos. 1 Link to post Share on other sites

Unfortunately limited preservation- here are some additional photos and scale, it’s pretty big if it is a Greenops which also has made me wonder about that ID. Maybe the Glabellar furrows will give a better clue. Thank you for your input! Link to post Share on other sites
Kane Posted August 29 Share Posted August 29 Judging by the new photos, it does seem to compare favourably with Bellacartwrightia. 1 Link to post Share on other sites
NoahW24 Posted August 29 Author Share Posted August 29 Update: the non-vibes-based evidence for Bellacartwrightia as opposed to Greenops so far: -Columns of 8-10 lenses, as opposed to the usual 7-8 of Greenops -Lack of pustules on glabella (might be due to internal mould vs shell) -Larger size(?)
