Hello All! For awhile I've known the Keyser Formation hosted eurypterids, and today was the day I encountered it! Me and 2 geologist gained access to an exposure on private property and were surveying it when I found a waterlime bed with overlying mudcracks, I would start my typical survey of the bed when I encountered a segment, and it just got better from there. Unlike other horizons I've collected all over this layer is not very dense, but consistently the bed was producing. After about 4 hours of intense digging I decided to call it quits for the day. 2 different and distinct eurypterid Species have been collected, one is some sort of Pterygotid likely the genus Acutiramus, and the other is the genus Erieopterus. The Erieopterus differs from the only other Devonian Eriopterus, Erieopterus microphthalmus in its head shape, with it being wider and the eyes being spread further. The best specimens collected were a plate with 2 heads on it and a Tergite from a pterygotid. Ill attach some pictures below. Top to Bottom: Erieopterus sp. Double head Erieopterus sp. (Note the legs on the left specimen) Pterygotid undet. close up of the scales, Pterygotid undet. Layer specimens were collected from.

Greetings forum members! I was looking through the last rocks from my latest fossil hunt and I found this interesting piece. Its a partial Pterygotid body segment! I had broken it and I thought I had thrown it back but apparently I kept like 80% of it. I glued it back together as best I could last night and was looking more closely when I found something interesting. I’m not completely sure but I have a hunch that the one end of this fossil might have predation marks from a larger Pterygotid. Could this be true or did it just break weird when it was molted? I was wondering if anybody on the forum could help me out with this. Thanks for looking! Owen

Hello all! As I’ve been taking a closer look at some of the rocks from my previous fossil hunt on August 22, I have been finding some pretty cool fossils that I overlooked at first. I am going to show some of the more interesting ones on this post. Enjoy! ~ Owen
