Hi all! Please tell me this is more than a concretion! Edit to add location: Found in Lansing, NY. The matrix is a dark grey/black shale that breaks under it's own weight when I lift pieces and it breaks off into big chunks unlike thinner layered shale also in the area. I think I see crinoid stems and wonder if there are other fossils (Hallotheca acils ?) under a shallow layer of sediment making the cone shape appear to have rounded sides or is this something completely different (I think I've been finding nice molds of Hallotheca acils in close proximity to where I found this guy today). I hope to return tomorrow and find the other half to try and glean more information from the molded half. It was the only fossil in this piece of stone but I found two species of Rugosa and multiple species of Brachiopods in similar stones lying within a foot of it. It's delicate and I've wrapped it in wet paper towels and placed in a shallow dish with water. The entire item measures 2cm wide x 8 cm long. Thank you for your time

Hi all! I just got back from a little hunt with the kids along Etobicoke Creek here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician), and I'm wondering if I perhaps found a trilobite pygidium? Here are some pictures: Front of rock (lots of little branching bryozoans and some crinoid bits): Back of rock (where the possible trilobite pygidium is located - circled in red): Close-up of possible trilobite pygidium: What do you think? And, if it is indeed a trilobite pygidium, can it be identified any further? Thanks in advance! Monica

Hi all I got this pygidium not long ago. I thought I could solve this puzzle all by myself, but turns out it is much harder than I thought! Apparently the web has no real record of a trilobite who has a similar pygidium to mine from the Cambrian of Linquxia, Shandong, China... The chinese name for this type of pygidium is 龟石 (gui shi), which literally just means "Turtle Stone". I was wondering if any of you experts out there recognize the pygidium and has a species in mind Any help appreciated! Thanks, SP
