TNCollector Posted November 3, 2015 Share Posted November 3, 2015 (edited) I spent a few hours looking for trilobites in an Upper Cambrian formation in East Tennessee. The site was supposed to have a fair amount of trilobites, but despite searching the entire quarter mile long roadcut, all I found was this. My initial guess is that it is a tip of the cephalon of a trilobite, but it is really hard to tell, and I am not well versed enough in the topic to say for sure. Any suggestions? Thanks in advance!

TNCollector Posted November 3, 2015 Author Share Posted November 3, 2015 Pygidium? I could see it being a pygidium, but I can also see it being a cephalon. IDK Link to comment Share on other sites More sharing options...
ynot Posted November 3, 2015 Share Posted November 3, 2015 More pictures from different angels might help. I am probably wrong but I do not see a trilobite in this. Can not wait to see what others have to say. Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Rockwood Posted November 3, 2015 Share Posted November 3, 2015 I agree that different angles may change the perspective, but I don't see it being a trilobite either. It seems much too thick to me. Link to comment Share on other sites More sharing options...

I respectfully disagree that it is too thick. The shell thickness is less than a millimeter thick, however, I can see how my photos might make it look thicker. Here are some photos of the specimen. If it is not trilobite, what could it be? I have not seen something quite like it before in the Cambrian.

Plax Posted November 4, 2015 Share Posted November 4, 2015 I'd look in shaley intervals instead of the limestone if there is any. Sometimes these reports are deceiving because the abundant trilobites are only found in a very specific stratum. Link to comment Share on other sites More sharing options...
