Hello all! Just finished going through a small batch of matrix from the York River and found a some fossils that I need help IDing. 1. These ones strike me as some sort of polychaete jaws, but not sure. 2. Some denticles or teeth but they seem a lot different than the skate (Rostroraja sp.) that I've been finding (see 2.1). These do not have the cusp or base morphology that I've been observing and are quite smaller. 2.1 Rostroraja teeth Thanks so much! Miguel M

Mazon Creek Formation (Fossil Identified) Lepidostrobophyllum
TheGoblinKing posted a topic in Fossil ID
My great grandfather majorly shaped who I am today by getting me introduced to biology, paleontology, and earth sciences at a young age. He left me with many fossils that he had gone out and found himself, picking about in the Mazon Creek Formation of the Carboniferous. Among the ferns and leaves I had found this one, it looks a lot like a negative impression of an invert to me, although I could also see it being a leaf impression. I'm pretty immature so I'd appreciate any help, thank you- 28 replies

These 2 items are cemented into a shrimp burrow from the Mooreville chalk, upper Cretaceous of central Alabama. Each one is about 2 mm in length. they don't resemble anything I'm familiar with. I was going to acid clean them but need to know if they are calcareous first. I'm hoping someone knows what they are. Also, can someone tell me how to draw lines on these photos to highlight features?

PrehistoricWonders posted a topic in Questions & Answers
Hey everyone! I know it’s a long shot, but I’m currently in Montana and will be for abt 1 1/2 more days, and was wondering if anyone had any ammonite sites in Montana, South and North Dakota, or Wyoming, I’d be willing to trade a spot, or take whomever it was out to Ernst quarries, or trade fossils for the site, if anyone’s interested in that, please let me know.
