MarcusFossils Posted April 13, 2018 Share Posted April 13, 2018 Hi all, This little pygidium was found in the Pontgravé River Formation near St-Mathias, Quebec. This strata is part of the Richmond Group. As far as I can tell, this is a new occurrence of either Eomonorachus, Tricopelta or some other similar trilobite from the US. Here's a PDF that I found useful: https://www.researchgate.net/publication/237172420_Ordovician_Pterygometopidae_Trilobita_of_North_America What do you guys think? @piranha, your vast knowledge will surely solve this riddle in a second or two..

piranha Posted April 13, 2018 Share Posted April 13, 2018 The linked paper has pterygometopids reported from Quebec. I would label it: Pterygometopidae sp. indet. 9 Link to comment Share on other sites More sharing options...

The Lord of the Trilobites strikes again! It is amazing how good piranha is at identifying those little trilo-bits! Darwin said: " Man sprang from monkeys."
