Stingray Posted September 24, 2016 Author Share Posted September 24, 2016 Terataspis was what @FossilDAWG thought it might be. Link to post Share on other sites
Fossildude19 Posted September 25, 2016 Share Posted September 25, 2016 Great find, Chris! I agree with Don, - definitely Terataspis. Don't know if you have the Linsley PDF. This is the plate of Terataspis from it. Thanks for posting it! Regards, 4 Link to post Share on other sites
Stingray Posted September 25, 2016 Author Share Posted September 25, 2016 Tim, Now I have to slowly uncover it and see how much is under there... Thanks for the link. Link to post Share on other sites

Jeffrey P Posted September 25, 2016 Share Posted September 25, 2016 That's a helluva find. I think it is better than the other one you showed me and I have no doubt that it is Terataspis. How big is that specimen? I know they could get pretty big. Link to post Share on other sites

FossilDAWG Posted September 25, 2016 Share Posted September 25, 2016 That is a very nice chunk of a Terataspis. The intact spines are especially rare, hopefully you'll be able to salvage them. I think there is a bryozoan colony attached; bryozoan epifauna were not unusual on large trilobites like this. Great find! Don 3 Link to post Share on other sites

funfordds Posted September 26, 2016 Share Posted September 26, 2016 Nice find. What formation or county did this come from? In the past i've come across some similar parts of what I believe to be terataspis. Link to post Share on other sites
Stingray Posted September 27, 2016 Author Share Posted September 27, 2016 Hi Funfordds, . United States, NY, Coymans formation, Devonian. They are strange critters 1 Link to post Share on other sites

GerryK Posted September 30, 2016 Share Posted September 30, 2016 What you have is definitely not a Terataspis. The ornamentation on the glabella is wrong for Terataspis. Terataspis has many small pustules, while your specimen has few large pustules. I’m having a hard time determining what trilobite you have. You state that it comes from the Coeymans Formation but I don’t know of any Lichid that comes from the Coeymans. It looks similar to Oinochoe pustulosus from the New Scotland Formation but is different with the long spines at the back of the glabella. If it does come from the Coeymans Formation, you may have something new and if it is, carefully prepare it. 4 Link to post Share on other sites
Stingray Posted September 30, 2016 Author Share Posted September 30, 2016 Gerrry, Thanks I will verify my geological formation as there are many thrust faults in that location. Identification - The find does contain small ( pustules) they are so small I cannot get a better picture of them, as for the quantity of them may not be as numerous as descriptions of current finds. My thought, It may be possible as they molted they became spineyer as this is a small specimen for T.Grandis if it is one. I sent another part of a cephalon to a university in Georgia and the professor there seemed to think it was that species , but with such a small piece he wasn't 100% based on his post above. I guess as I move along on the prep, although I don't think there is much left that I'm qualified or have the proper tooling for I may just bring it to the museum. Thanks for the insights into this article. Link to post Share on other sites
Stingray Posted September 30, 2016 Author Share Posted September 30, 2016 I stand corrected it's Helderberg Limestone Link to post Share on other sites
