Cluros Posted August 29, 2015 Share Posted August 29, 2015 Hi fellow Fossil Forum members. I have been collecting Vermont trilobites in a location for awhile and am wondering if both of these trilobites are Flexicalymene senaria or do I have two different species. I keep getting conflicting opinions from my fellow collectors. I collected both trilobites from the same area. When I prepped them I thought that were some significant differences in the cephalons. Any thoughts would be appreciated. Link to comment Share on other sites More sharing options...
FossilDAWG Posted August 29, 2015 Share Posted August 29, 2015 I don't think they are the same. The one with the circle around it seems to have more of a "bell-shaped" glabella, which suggests it may be a Gravicalymene. Don Link to comment Share on other sites More sharing options...
Cluros Posted August 29, 2015 Author Share Posted August 29, 2015 I forgot to mention they are middle Ordivician from the Chazy formation. The photos of Flexicalymene senaria on the web look nothing like the cephalon on the left. Link to comment Share on other sites More sharing options...
