  9. Cephalopods? & Crinoid Pieces

    This is about a 6" x 6" rock with crinoid pieces that are mostly on one side and what are maybe some straight shelled cephalopods. There is this circular piece that I don't know what it is. It is somewhat translucent when wet. There are other circular pieces as well as misc. bits and pieces. Can anyone confirm whether these are cephalopods and if the circular pieces are related? Thank you for looking. Patti
  10. Trilobite, Ammonoid, Unknown

    I found my largest trilobite so far at 2 1/2 ". I am guessing that it is a Phacops. It was found by a creek and is worn but made me happy. By it was another rock that is very busy with some parts that remind me of a trilobite. I don't know if anyone can tell me what if anything I am looking at. The rock is 3" x 2 1/4". There does appear to be a brachiopod on one side. The third is an ammonoid found by Hemlock Lake and I wondered if it could be identified. It is ~ 1 3/4" at the widest point. The lake side is in the Sonyea group but It could have come down from higher up above the lake which gets into the upper Devonian. Thank you for looking. Patti
  11. Fossil Fragments From Hamilton Group Shale

    I collected some Hamilton Group shale to search for microfossils (Middle Devonian), and some of the pieces I ended up with showed an odd structure after I washed the mud off: The largest rock is 3 1/4" long. Breaking up a large chunk of shale, I also found a very nice brachiopod. I haven't looked it up yet, but I thought I'd share it here. It's 1 1/4" long: It's interesting what odd things I find when I grab random rocks for microfossiling!
  12. Some Micros From The Windom Shale

    I've been experimenting with breaking down some Windom Shale from Penn-Dixie, and I think I have some ostracods: I have a few other interesting bits, too. Are these echinoid spines, micro-belemnite bits, or something else? And then there's this object: That's a small sampling. I also have found lots of brachiopod pieces, which is not surprising. The shale is rich in macrofossils, especially brachiopods, trilobites, horn corals, and occasional straight cephalopods.
  13. I was planning to attend the Museum of the Earth's outing to Jamesville Quarry and knew that gas would be the primary expense for the three and a half hour trip each way. So, I decided to make the most of it and head up there two days early, camp, and visit some very productive Middle Devonian sites my girlfriend, Valerie and I explored last May. 11:30 Thursday morning I arrived at Deep Springs Road quarry near Lebanon in Madison County. It is an excellent exposure of the Windom Shale and was my favorite site on my last visit to the area. A wide variety of well preserved fossil invertebrates are profuse in the relatively soft shale where they can usually be extracted without too much difficulty. Many preserved in calcite, can be removed entirely from the rock. Within the first fifteen minutes I uncovered a small Greenops trilobite cephalon. Several minutes later, I found a complete Phacops rana enrolled. The very top of its cephalon shattered when I removed it from the rock, but otherwise it was perfect. Here's a picture: Almost as exciting was the wide assortment of excellent bivalve fossils I found. This is a Grammysia: Brachiopods were also abundant. This is Athyris spiriferoids: Also found other partial trilobites, crinoid stems, gastropods, and a tiny goniatite. I was going to spend a few hours there and then head over to a nearby exposure of the upper Ludlowville Formation, but I ended up spended the whole day at Deep Springs Road. Friday morning I drove twenty minutes to Pompey Center and a famous roadcut along Route 20 where the Skaneateles Formation is well exposed. Within minutes I found a nice large Cornulites, a bivalve: There were other bivalves as well. This is Modiomorpha: One of my goals was to find a large Spyroceras, a straight-shelled nautiloid. Last May we collected a number of fragments. Friday I was hoping for a more complete one. Wasn't to happen. This is one of the fragments I collected: Also found a number of fragments of Michelinoceras, another straight-shelled nautiloid. The surprise of the morning was a two and a quarter inch goniatite found lying free on top of the roadcut: It was nearly an hour drive east to the tiny hamlet of North Brookfield through stunning farm country. Nearby is a sandstone quarry exposing the Skaneateles Formation which is famous for its abundance of Dipleura dekayi, a huge burrowing trilobite. Valerie and I only spent a short while there last May. Still I was able to find three Dipleura cephalons, a pygidium, also an enormous bivalve, brachiopods, and cephalopods. The first rock I split open on Friday revealed a small, but complete Dipleura cephalon, better than any of the ones I found on my last trip. A few minutes later, I split another sandstone slab and I immediately focused on a bivalve in the center, but then my eyes drifted down to something unusual in the corner. There was the thorax and pygidium of a young Dipleura. When I turned the slab on its side I saw the cephalon still attached to the body, pointing downwards. Even though it was young, it is at least three times the size of the adult Phacops I found the previous day: Later I found a number of pygidiums and some bivalves, including one very large Leioptera. Saturday morning, the Museum of the Earth group was planning to congregate at 11:00 so that gave almost an hour an half to return to Pompey Center. I decided to focus on the lower portion of the roadcut which is shale where last May Valerie found a perfect Paleozygopleura, a lovely corkscrew-shaped gastropod. I was hoping to find one myself. After a while of digging in the crumbly shale, I found a small complete Greenops trilobite. Unfortunately the fragile body was stuck in the imprint and much of it crumbled when i removed it. However the imprint is perfect: Later, I found my own Paleozygopleura, though not as good as the one Valerie found: I joined the Museum of the Earth group at Jamesville Quarry. That excursion is very well documented by Marley's Ghost so I need not repeat anything. I did find a number of teeth of Onychodus sigmoides a rhipidistian fish as well as other small unidentified fish parts. In the Nedrow member of the Onondaga Limestone I found excellent examples of Favosites, a tabulate coral. I brought a number of pieces back. They really show the structure well: Well, that's about it. It's been hectic the past few days organizing, sorting, and cleaning my specimens as well as getting back on track with all the personal and professonal matters I neglected while I was away three days. All in all it feels good to be back home.
  14. 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.
  15. Last Friday I visited the Helderberg Plateau southwest of Albany NY for the first time in search of Middle Devonian fauna. In a thin bed of dark gray silty sandstone in one of the cliffs along Hannacroix Creek, preliminarily called the Hannacroix Ravine Bed, I collected numerous ammonoids, straight-shelled nautiloids, tiny bivalves, and plants. Brachiopods are rarely found in this bed and none were found that day. The fauna was similar to those I've found in the Dave Elliot bed exposed along Route 209 just west of Kingston, NY except that complete ammonoids appear more abundant here. The ammonoids are the goniatite, Tornoceras mesopleuron. I found three nearly complete individuals roughly about an inch in diameter and two smaller ones, one less than an eighth of an inch, as well as numerous partial specimens. One slab contained three large partial specimens lying side by side. Could only upload one photo taken from my cellphone. Any suggestions on to how to upload the rest?

  17. Found these pieces awhile back from a sample of the Wanakah Shale near Bethany, NY. They remind me of crab but the Middle Devonian is too old for them. I have the irrational fear that I put my trowel through a complete trilobite while collecting the sample! I have more pieces but these seem to be representative in terms of surface ornamentation and shape. Any ideas? Acryzona P.S. The white squares in the photo are 3.5mm on edge
