Jeffrey P Posted November 8, 2016 Share Posted November 8, 2016 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.

Jeffrey P Posted November 8, 2016 Author Share Posted November 8, 2016 Also found this one which is pretty damaged, but larger than the above specimen: Link to comment Share on other sites More sharing options...
Jeffrey P Posted November 8, 2016 Author Share Posted November 8, 2016 Also found these two nautiloid specimens; probably Michelinoceras: Link to comment Share on other sites More sharing options...

Shamalama Posted November 8, 2016 Share Posted November 8, 2016 Great finds and that Tornoceras is a beaut! You can just see some of the suture lines along the edge of the piece, nice! -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
