Today on a hunt I found on of the most unusual trilobite pygidiums I've ever seen from new york and cannot find anything out there to compare it to. Unfortunately the site is imported material from an unknown quarry upstate so all I do know is that its from the Devonian of New York based on other material found there, unfortunately I cannot attach a formation to this one. Also its also fragile and a very partial piece thats unpreped, I think its a ventral display. This maybe a head scratcher so maybe the trilobite experts here can help weigh in on what this can possibly be.
