Tornoceras sp. (goniatite) Middle Devonian Windom Shale Moscow Formation Hamilton Group Deep Springs Road quarry Lebanon, NY. collected 5/23/15 -
Last Saturday, 5/23/15, a group of Fossil Forum members from five different northeastern states gathered at a quarry off Deep Springs Road in Lebanon, NY. to hunt for Middle Devonian marine fossils in shale from the Moscow Formation. This writer first visited the site, featured on Karl Wilson's website, in late spring of 2013 and since has returned six times. Last fall I introduced Tim (Fossildude19) to the site and we came up with the idea that this would be an excellent location for a TFF meet up. Tim made the connections and plans with other TFF members, a date was finally agreed upon, and this writer went to the site on the weekend of 5/3-5/4/15 to check out the parking situation and to gain permission from the owner, a local farmer. Primary features of the site are the sheer abundance of fossils (There are fossils on just about every rock.) and biodiversity, just about every type of marine fossil from the Middle Devonian can be found there. The site differs from others further west, especially those in the Finger Lakes/Buffalo region in that it was much closer to the Catskill Delta to the east, therefore the waters were probably cloudier and the fossil assemblage different from those further west. Corals are rare and bivalves, gastropods, and cephalopods more abundant than those other sites in Western New York. The site is located amidst lovely rolling hills, and fields of corn and cows grazing. Many Amish live in the area. Weather that day; cloudless blue sky, temperatures in the low sixties, was perfect for collecting. Tim, from Connecticut was the first to arrive. Then I showed up, then Mike (Pagurus) and his wife, Leila from Massachusetts, then Rob (snakebite 6769) and his family from Vermont, Carmine (xonenine) from Buffalo, NY., and finally Dave (Shamalama) from the Philadelphia area. Here's a group shot taken by this writer.

Hello everyone! At around at the end of August I started making frequent visits to Mimico creek in order to collect fossils before the next winter comes (hopefully it wouldn't be as cold like the previous one was), and also the other reason was because of the developments going on at the creek. I was fearing that they would eventually cover up all the exposures I know of. I made my way through the woods and shrubby areas to reach certain exposures.

Treptoceras crebiseptum specimens. The one on the left comes from Mimico creek. The blue grey one on the right is covered with bryozoans and comes from the Humber river area and is complete is actually missing the living chamber. Both belong to the Georgian Bay Formation.© (©)

Collecting Middle Devonian Cephalopods Etc., Near Albany Ny
Jeffrey P posted a topic in Fossil Hunting Trips
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?

Independence, Iowa, Cephalopod Collection Donated To University Of Iowa

UI houses rare cephalopods donations, The Daily Iowan, November 2, 2012 http://www.dailyiowa...etro/30671.html The donated fossils were recovered from two limestone quarries in the Independence, Iowa, area five years ago.

Thought this could be a clam, but not sure due to the extension of shell. Maybe a brachipod?© Tammie Harper

Nancy and I made a two hour stop at the Devonian borrow pit/rubble slopes at Deer Lake, PA on Sept. 1, on our way to St. Clair (along Route 61). These are very steep rubble-covered slopes, a bit tricky to climb and navigate. There are several locations. The mining slopes are posted so we avoided them. There are slopes behind two restaurants, and slopes next to a parking lot although some of the back slopes are posted. I spent most of my time at the top of the slope and Nan cracked shale rocks at the bottom. Nan found a 8 cm long cephalopod which is discussed and pictured in the Fossil ID section (http://www.thefossilforum.com/index.php/topic/31741-devonian-cephalopod-from-deer-lake-pa/page__hl__%2Bdeer+%2Blake ) The Deer Lake site is described by several sources as having an extremely large and diverse variety of Devonian fossils, from ammonoids and brachiopods to cephalopods and trilobites. We found no ammonoids or trilobites - however, I found some very impressive "death assemblages" that confirmed the variety of fossils here, including a nice internal spirifid brachiopod that later separated from the substrate. The shell in Image 10.1 seems to show the pattern (and possibly color) of the original shell (look at the brown and beige stripes that cut across the contoured grooves). Also, Image 11.1 looks like a portion of an Orthonata shell although it could be something else. Some of the assemblages are artistically arranged and are very cool. The iron content creates some bright orange fossils and the shale tends to come in purple and orange colors, including some olive green shale. This orange and purple coloring is very impressive. Our goal is to find a much larger "death assemblage" in order to collect a specimen that would be suitable for display. On the way to this site, we stopped at a local roadcut near our home that we had been eyeing and found a lot of olive green colored shale. In a very quick 10 minute look, we found some trace fossils but nothing significant although if we find anything that is well defined it will be impressive because of the unique color of the shale. We plan to spend more time at the Deer Lake slopes, on a future visit. Nancy wants to crack open some of the larger rocks and I want to extract some larger slices of shale, to get a nice display piece. We have not had time to go through the fossils to identify them - we have a large collection of Devonian shell fossils from several different sites and I plan to spend the winter identifying these. If anyone would like to offer identifications for any of these now and save me some time poring over the fossil books this winter, you're welcome to do so - I've numbered the images for easy ID.

here is some thing i have been wondering for the last few days. i have found that most ancient cephalopods are divided into nautiloids (cephalopods with shells) and coleoids (cephalopods without shells). but i recently read that a fossil of the orthocone Michelinoceras was found with 10 arms and a radula with 7 teeth per row. arent those coleoid traits? i know that an ammonite fossil was found with those features and was thus determined to be a "coleoid". is it possible that this grouping is arbitrary and that many more supposed nautiloids are coleoids that just happen to have shells?
