So reading through some old posts and seeing @Jeffrey P finds, I decided to get out today and take a trip to the Dave Elliot outcrops. After digging through what Jeff left behind I decided to take a look around that area. I’ll post more as I get them prepped but here’s a few to get started. Largest intact Horn Coral I have ever found.

Hello Forum, I was vacationing in Kingston NY last weekend and went collecting along the Middle Devonian road cuts along route 209 and 9w. Hope the experts here can help me identify what I saw and collected! The first image is a fossil, too fragile to remove, in the 9w road cut that stood out from the masses of shells surrounding it. The rest are bulb like forms (corals?) collected from the loose shale of the Route 209 roadcut. Any ideas? Many thanks to the NY enthusiasts posting here that inspired my search. - Ben

Hunting Devonian Cephalopods in Hannacroix Ravine, Albany Co., NY.
Jeffrey P posted a topic in Fossil Hunting Trips
Today I returned to Hannacroix Ravine, a site in Southern Albany County, NY. (Helderberg Plateau) I last visited over three years ago. It is a beautiful site along a narrow cliff lined ravine, however it is tough to get to requiring a steep decent from the road and making one's way through thick prickly bushes and downed trees. No wonder why I've avoided this place in favor of road cuts and quarries. The stream itself was barely flowing, more just a series of shallow pools and mud. It was a cool, sunny day (temperatures in the 40s and later low 50s), but perpetually shady in the deep ravine. I was collecting from deep water strata in the Dave Elliot Bed, part of the Mount Marion Formation which is part of the Marcellus Shale which forms the lowest part of the Middle Devonian Hamilton Group. The rock was primarily siltstone, not terribly hard to remove decent sized pieces from the wall which hung precariously overhead. I was forever fearful a bunch of it would collapse and land on me. Some pieces did come down on their own, but none came close to hitting me. Biodiversity is very limited here: some small bivalve shells and goniatites and straight-shelled nautiloids. There appears to be even less diversity than the Dave Elliot deep water site near Kingston. Spent about six hours- the first four were mostly a dud, but in the last two found some nice goniatite and nautiloid specimens. Did even better than I did the last time I was there. The prize was this goniatite, Tornoceras mosopleuron, the best one I've collected from this site and better than any of the ones I've found at the Kingston site.

Finding Terrestrial Devonian Plants In A Marine Deposit
Jeffrey P posted a topic in Fossil Hunting Trips
Last summer I posted a description of an excellent, but hot day collecting from the Dave Elliot Bed, at a Middle Devonian site just outside Kingston, NY. The site, as I described, is a thin layer only inches thick, rich in tiny bivalves and cephalopods (straight-shelled nautiloids and the goniatite, Tornoceras). Eumetabolotoechia brachiopods and fossils of terrestrial plants are also present as are occasional rare fossils like conularids. It is a deepwater site and the limited fauna are specially adapted to those conditions. The plants probably originated from forests that lined a river delta somewhere to the east, remains of which have long ago disappeared after millions of years of erosion. The plants which include branches of Psilophyton and Lycopod bark with leaf scars are what remains of this very ancient vanished forest.

Last Wednesday was a sweltering 94 degree high humidity day. I had an appointment in the area and couldn't help checking out a favorite site; the Dave Elliot bed on Route 209 just west of Kingston, NY. The bed is highly fossiliferous silty sandstone, just a few inches thick in an exposure that's 30 to 40 feet high. The bed is Middle Devonian age with tiny bivalves and cephalopods dominant. I spent a total of three hours chipping away hunks of rock from the crumbly cliff and had my best day there so far: seven complete or nearly complete goniatite ammonoids, Tornoceras mesopleuron. a three and a half inch nearly complete straight-shelled nautiloid, Michelinoceras sp.?, five Eumetabolotoechia brachiopods (normally I just find one or two per day), a tiny spiriferoid brachiopod (unidentified) I've never found at this site before, bivalves, Nuculites sp.?, the twig of a fossil plant, and two other unidentified fossils. The day was well worth it, despite the heat. The unidentified fossils I'll show Dr. Bartholomew, professor of paleontology and stratigraphy at the State University near where I live. Dr. Bartholomew is doing an extensive study of the Dave Elliot Bed in eastern New York. The Dave Elliot fauna here in Kingston is similar to the fossils from Hannacroix Ravine except that brachiopods are rarer at Hannacroix. The presence of well preserved fossil plants in marine sediments would suggest the presence of a nearby river that carried their remains from some terrestrial habitat. The absence of corals and relatively low species diversity also suggests the water contained a large ammount of sediment making it hospitable to only those creatures who could adapt to this cloudy environment. Finding fossils, especially cephalopods, and speculating on what the prehistoric environment was like is a great source of fascination for me. I try to get there whenever I have a chance. Less than a mile north of here, also on Route 209 is another even older Middle Devonian fossil bed that produces abundant spiriferoid brachiopods and rugose corals, and about a mile and half west is a site where spirifers and occasional bivales and cephalopods can be found.
