  4. Gastropod

  5. Athleta Petrosa, Perhapsa?

    I'm no gastropodiatrist, but I think this specimen is Athleta petrosa. It was found in Shoal Creek in Austin, TX, which has everything from Cretaceous to last Thursday, but I suspect this is Eocene. It's not the most pristine gastropod I've ever found, but it has some nice detail on the whorls. What do you think?
  6. Some sort of Brachiopod?

    From the album Backyard Firepit Rock with Surprise

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

  10. Devonian Gastropod Id - Tully Ny

    Would appreciate confirmation to identify these gastropods from our recent Tully NY trip. The attached JPG shows the gastropods we collected at Tully (at least we think they are all gastros). 1a and 1b. 2. 3a, 3b, 3c. 4. 5. 6a and 6b. 7a and 7b. Thanks in advance!
  11. This is a "first look" at a few of the interesting specimens we collected last week at our visit to Tully, NY. The owner of the property was kind enough to give us permission to do some collecting so we gave it a concerted effort and these are just a few of the dozens of samples. Here is a list of samples included here (more coming soon) - Note - those items that are tentatively identified/confirmed are updated with the ID: 1. Crinoid and Crinoid Disk - this is a beautifully articulated 7 centimeter long crinoid stem which Nancy found attached to the shale substrate exactly as shown in the photo. Also, a small crinoid disk was associated with the stem, located immediately next to the crinoid shaft as shown. Any ID information on this? 2. Mediospirifer - 1a, 1b and 1c is beautifully articulated and was extracted intact as shown. This we've learned is the "internal" view of this creature without the shell, which is fascinating. I've also added two views of a spirifer shell fragment we collected intact but this was identified in another post as probably Mucrospirifer. It's interesting to compare the spirifer without the shell and the spirifer shell fragment. Still not sure if these are two separate spirifers (medio and mucro) or the same. 3. Spyroceras 1a and 1b (side view) (Devonian Cephalopod) - Nancy found this section of a stem and as you can see from these two images (1a and 1b) it is flattened. 4. Glyptotomaria or Cyclonema? - This Devonian gastropod is nicely defined but buried in the shale. We believe this is Glypto rather than Cyclonema because Glypto has been reported at the Tully site. A full jpg sheet of the gastropods we found at Tully is included in the Members Gallery. 5. Chronetes - Brachiopod - This is a familiar shape and common at Tully. 6. Delthyris- Devonian Brachiopod. 7. Greenops Pygidium - Trilobite - I found this at the bottom of the shale formation behind the Best Western Hotel, just lying exposed below a small eroded gully. Any idea what flavor of trilobite this might be? Thanks everyone for identifying these specimens.
  12. Ammonite In Pa

    I photographed this Ammonoid fossil which is about 5 to 6 inches across on a very large block of rock, on a breakwater near a bridge near Williamsport, Pennsylvania...assume it is an ammonite. No other information. The rock was too large and too solid to fragment or reduce in size. We did not "collect" this specimen but given the enthusiasm from our fossil hunting friends, we're thinking of going back to get it. Any comments would be appreciated.
  13. Is This Loxonema?

    My original post asking if this was Loxonema (gastropod) was answered and we now believe this is a Paleozygopleura because of the vertical grooves on the whorls. We found this earlier June 10 at the Montour pit in central Pennsylvania - Devonian shale. We will post other finds soon from our very busy weekend trip, which included Antes Creek, McIntyre Mountain and Montour. Our Red Hill fossils from this trip are posted in a separate members gallery.
  14. Various Fossils 2

    From the album Western Ky Fossil Hunt

  15. Just a nice little gastropod. I like the algae thats growing on the matrix! Here it is from a couple different angles! I have been wrong on almost every gastropod ID I've ever attempted so I am leery to venture a guess. Gastropod is all ya get! pic1 pic2 pic3 Found in the Winterset limestone, Kansas City, Jackson county, Missouri. (edit) possibly Meekospira ? from http://www.kgs.ku.edu/Extension/fossils/gastropod.html for comparison This Pennsylvanian gastropod, which probably belongs to the genus Meekospira, has a shell with a very high spire. It was collected from the Leavenworth Limestone Member of the Oread Limestone in Douglas County.
  16. I pulled off the side of the road because this mud slope looked interesting. It is near downtown Kansas City Missouri. I found it to be very sparse in the way of fossils however I did find one lone gastropod. I cannot make a positive ID because it is badly weathered and/or poorly preserved. I tried many different ways of photographing it but no matter what kind of light, angle, distance or camera settings, I could not get any of the details to show up well. I penciled in the spiral and the sutures I can see when the fossil is in hand. Just an interesting piece and thought it odd that this was the ONLY fossil I found on this entire hillside. Check it out! pic1 pic2 pic3 pic4 pic5
  17. I am cleaning up and labeling all my fossils, and thus i have the fun task of trying to identify all of them. Problem is, I am no fossil expert, and so I am here once more to ask for help. First up, corals. The brown coral on the left comes from Africa, and I purchased it from the HK ebay dealer, gaofudev. The other three corals below were picked up from the beaches of Singapore, Thailand and Bintan. Next, my shells. The bivalve on the left came from Whitby, Yorkshire, and is supposedly Jurassic aged. The gastropod on the right is most likely Turritella Terebra from Indonesia, however I need help in determining its age. Lastly, my coprolite. This one is likely a dino coprolite from the Cretaceous age, and is from Madagascar. I can't confirm that however, and it would be nice of someone to help me double-check on it. That's it! Thanks for helping!
  18. These elegant shells are highly sought after here in Kansas City: Perfect specimens are hard to come by. They tend to be hollow, and often break when extracted from the limestone. This one was lucky: The bottom of the shell is flat: They can reach up to four inches in size. This is my largest: Some specimens retain a color pattern: Another, with slightly better colors: Here, some sponges had bored into the base of the shell: Euconospira isn't the largest gastropod we find around here. That honor goes to Shansiella: This one is even bigger, but it is broken. Hidden from view here, the shell extends all the way to the left edge of the rock: A smaller, but higher quality Shansiella:
