MarcusFossils Posted March 10, 2018 Share Posted March 10, 2018 Hello, A buddy recently gave me this snazzy trilobite, but unfortunately the label on the back said 'Metacanthina', which I think is wrong.. Is this a New York Bellacartwrightia?

Kane Posted March 10, 2018 Share Posted March 10, 2018 The pygidial spikes/lappets appear too short and blunted to be a Bellacartwrightia whiteleyi. It is an asteropygid of some sort, and if it comes from NY (possibly?), @GerryK would likely know. 3 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
GerryK Posted March 12, 2018 Share Posted March 12, 2018 Your trilobite is a Bellacartwrightia and it does like like it came from New York. I can't determine the species without a good picture of the pygidium. Link to comment Share on other sites More sharing options...

GerryK Posted March 13, 2018 Share Posted March 13, 2018 After looking at the pygidium pictures, I’m not sure what species you have. The pygidium lappets are short, wide and flat which eliminates B. whiteleyi and Bellacartwrightia sp. from Penn Dixie Quarry. The closest species your specimen comes to is B. phyllocaudata. If your buddy friend knows the locality, that information may help. 2 Link to comment Share on other sites More sharing options...
