From the album: Eurypterids from New York
A personal favorite, this specimen was collected by the late Sam Ciurca. Sam was a role model for me and his work is nothing short of incredible. This eurypterid is the early Devonian eurypterid Erieopterus microphthalmus from the manilus limestone probably the oleny member. -

I found all of these last year in Albany County, New York. They are from the Manlius formation. Some of them I just need the species name and others I have no idea what they are. Thanks

Monday I was in Schoharie County up on the Helderberg Plateau southwest of Albany, NY. In a roadside exposure of the Manlius Formation I picked up several pieces of rock with numerous Tentaculites specimens. There were also small brachiopods and ostracods. The Manlius Formation either represents the bottom of the Helderberg Group- the lowest of the Lower Devonian or the highest formation in the Silurian in New York. Tentaculites were originally thought to be related to mollusks or worms, but now are considered more closely related to brachiopods and bryozoans.
