Upstate NY Fossils
Some "random" marine invertebrate Ordovician and Devonian fossils from Upstate NY, that I collected long ago when I was an undergraduate geology major at Adirondack Community College (now SUNY Adirondack) going on amazing field trips with Professor Anson S. Piper, a true "one of a kind" geologist (and Revolutionary War re-enactor), all over NY State. These aren't particularly noteworthy, but more like good examples of the types of abundant invertebrate fossils that you might find in western and central NY. I am trying to identify some of these, as the location data are well gone (except for one of the rocks). I'll add my thoughts and I welcome corrections and other ideas greatly. - OK, this one I know from whence it came: a piece of Middle Ordovician limestone of the Trenton Group at Trenton Falls, near Barneveld, Oneida County, NY. Collected on a (what turned out to be) a "Guerrilla Overnight Camp Out" at the Falls (then Niagara-Mohawk Power Corp. property), in late spring 1974. So, at the top is an Middle Ordovician crinoid (echinoderm) with the columnal stalk, and, I think, some of the arms of the crown. Left center, there is a tail or pygidia of a trilobite (primitive arthropod), possibly the genus Flexicalymene. There are also stalked bryozoan fragments here, an encrusting bryozoan, Prasopora (pper right), along with disarticulated crinoid columnals, and a few brachiopods. This rock is a real "fossil hash."
