Formation: Bangor Limestone Age: Mississippian Found this location in a remote area of Alabama recently. I Haven't hunted the Bangor in awhile, so I gave it a shot. A fragmentary calyx. Northern Alabama seems to be teeming with these, as I found 8 others in a nearby locality as well. A complete, but squashed roller of a Kaskia? Fenestrella are found commonly articulated with their fans here. This was the best individual I found. My guess is these are Spyroceras? All of my nautiloids come from the Ordovicia

I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix

Are sponges a major source of Neoproterozoic C30 steranes?
Oxytropidoceras posted a topic in Fossil News
Great virtual talk about using biomarkers to determine the presence of sponges in the Neoproterozoic. What are the major sources of Neoproterozoic C30 steranes? Gordon Love, University of California, Riverside Virtual Seminars in Precambrian Geology, December 2, 2022 In addition, starting at 53:30, Dr. Love presents very specific arguments about why the cholestane biomarker recovered from fossils of White Sea Dickinsonia fossils are Quaternary contaminates and are not in any way associated with them. If so, this renders the arguments about whether the cholesta -
Hi, i recently received those very nice sponges from @badeend. I asse they're all Hexactinellids. I know identfying sponges even when you have them un grand is a hard thing to do. Any help to try a more precise ID is greatly welcome. Here is the number1, a glass sponges ? Kimmeridgian, Kalberbeg, Netherlands

Paleozoic Adventures in Kentucky and Tennessee October 2021
Jeffrey P posted a topic in Fossil Hunting Trips
Hi Everyone, In the latter half of last month I took a two week trip to Kentucky and Tennessee. My sister, her husband, two of her adult children, and my parents all live in the Elizabethtown/Louisville area and I was able to spend some quality time with them. Fossil collecting was also part of my agenda. Herb, my primary fossil collecting partner in Kentucky and I had a three day trip down to Tennessee planned. Before I went on that expedition, I was out with my brother-in-law driving around central Kentucky. He dropped me off for 20 minutes at the Upper Mississippian site at Wax where- 76 replies

A Day in the Lower Devonian with the New York Paleontological Society
Jeffrey P posted a topic in Fossil Hunting Trips
Yesterday, Tim (Fossildude19) and myself met at our usual meeting spot and with Tim driving and his downloads playing, we headed north to a planned rendezvous with the New York Paleontological Society's outing at Cobleskill Stone Products just outside Schoharie, N.Y. The weather was gorgeous- perfect really, sunny mid-50s. Fall colors were in full swing. We drove through the northern edge of the Catskills, arriving early at our rendezvous, the parking lot at the Cobleskill Stone Company. It was my first time there since 2013. I went on two previous NY Paleontological Society outings to this si- 28 replies

I foud these two stones on a fossil hunting trip some weeks ago. The fossil on the below stone seems to be a gastropod (size about 3 cm), but is the other a sponge? Anyone have an idea? Both are from middle ordovicium, Oslo-field in Norway. Martin

Alternate title: I found Pennsylvanian fossilized Sesame Wasa Crispbread; is it safe to eat? I have visited the Pennsylvanian Naco Formation east of Payson, Arizona several times this long hot summer and found some interesting sponges. My most interesting find was this 5 cm wide sponge that looked almost exactly like a Wasa Crispbread with sesame seeds on top. I was about to nickname it a Wasa sponge until I found out that it had a genus name: Stioderma. Pennsylvanian Desmoinian Stioderma occur in Texas. Link It is amazing how many fossils I have identified from the Pennsy

Hey everyone. I thought I'd share some of the things I found on my last fossil hunt. So.. Many.. Fossils! One might even say that there were a plethora of fossils. If I could, I would've taken them all with me, but sadly my backpack can only carry so many rocks. I was literally examining each rock I had, trying to decide which to carry back and which to leave behind and how many I could fit in my pants pockets before they started to fall down. Eventually I decided to just stop looking for fossils and hike back to the jeep. This lasted all of 3 seconds before I found another a beautiful by

I visited my favorite spot in the Early Kimmeridgian the other day and along with the usual ammonites, I came up with something quite interesting. It's a block out of the sponge reef facies with a Laevaptychus obliquus Aptychus as the center piece along with a Streblites tenuilobatus ammonite and a couple of smaller ones, a rhychonelloid brachiopod and even a little echinoid spine all attached to pieces of sponges. Everything is strongly calcified, so it's quite stable. I just had to abrade away the soft clay matrix and there they were.

Hello, I have been finding all sorts of neat rocks and marine fossils in the desert outside of Yuma, Arizona where the Colorado river had once flowed into a large ocean. Are these fossilized coral or sponges? I would appreciate an ID on the specimens, or speculations as to what they are? Thank you.

A few days ago I found a very productive fossil site in the Pennsylvanian Naco Formation in central Arizona. I went up to look at an interesting new track site in the Permian Coconino Sandstone NE of Payson that was found by a friend and is being studied by the prolific Spencer Lucas from New Mexico. Link The Naco Formation site that I just found, has the most diversity of sponges of any Naco site to date. It also has lots of large brachiopods. Photo 1 shows a 3.4881 × 10-18 light years (3.3 cm) long Composita subtilita brachiopod, the largest that I have seen.

Hi. I visited Wren's Nest, Dudley, UK last summer. Just wonder if the fossils shown in the photos were corals or sponges. They were not uncommon but both were possibly damaged by diggers who attempted to excavate them. My apology the subject was a bit out of focus. Thanks. KS

I've just added two sponges to my collection which I found recently in the Kimmeridgian Lochen Formation in the upper Danube Valley near Beuron. The first is the appropriately named Melonella radiata and the second is a Trochobolus texatus.

Fossils on Wheels received another generous donation to our education programs this week. TFF member @Herb sent us a box of super cool invertebrates. He sent us a diversity of fossils from the Southern US that cover a wide range of eras. These fossils will be given to students in fossil starter kits and used in hands-on activities. Herb's donation is also awesome because this pushes me to learning a lot more about invertebrate fossils. One of the best parts of teaching kids about natural history through fossil exploration is that I get to learn a lot. Good teachers learn and challenge themselv

I found these fossils on Jebel Hafeet, Al Ain, UAE. The second rock looks like there is a criniod in it, but is more possibly a type of sponge. The first rock has quite a few things in it, including some type of coral. I would like to know what these really are.

These are all over our desert property in southeastern Cali. Various shapes, sizes, textures, and colors but I grouped some similarly textured ones for this photo. The ones pictured in the group are all lightweight with the texture of coral but we have many others with the same shapes & paisley-like designs (hard to see in photos) but made of smoother rock. I thought for a long time the pink thing in the last set of photos was someone's old spilled paint. It's about 12" wide. Any ideas?
