Show us your Devonian Epizoans & Pathological Brachiopods!
Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 174 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.

Im new to Missouri and live on the ordovician exposures of central Missouri. Anyone want to discuss useful information and educate me on my journey of fossil hunting here? Ive been finding a lot of gastropod and a few other things but im having a hard time learning to spot things other than shells.

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?

Most come from Illinois, and are as I figure corals and spines; question is what kind, and which? I apologize in advance, but instead of posting 20 threads for each one, I’m going to spam this one with all my sponge, coral, etc inquiries. So please be patient! (Thanks again guys for all your help! I only post the ones I cannot 100% identify via books and internet; unfortunately I gotta snarge ton more yet to come.) Here are items #1-3...

Lack of snow cover and warmer than average temps allowed me to explore and collect sponges and corals from the Pennsylvanian Naco Formation in central Arizona, north of Payson. Widespread chert of the Beta Member suggests that silicious sponges may have been common. Several have been identified but many more exist. I have seen and collected several undescribed species. Dilliard and Rigby have described several sponges including Chaunactis olsoni which I found in the area: The New Demosponges, Chaunactis olsoni and. Haplistion nacoense, and Associated Sponges from the. Pennsylvanian Nac

Lately if you have seen some of the topics I've started, these trips revolve around an Ordovician reef I came across by the Credit River in Mississauga, Ontario. One of the few things I discovered while exploring these spots is that there are plenty of Stromatocerium sponges which I red is a stromatoporoid. My question is, can anyone lead me to any papers about the growth forms of Ordovician stromatoporoids? I have found specimens of stromatoporoids and from the way I see it, some of the specimens I found of the same species have different growth forms. Some have those things they call monticu

Hi all, I'm fairly new to this forum and fossil hunting in general. I need help identifying these, idk if they are coral, sponges, posibally bone or what. These were found in NE Kansas, in a rock deposit full of bryzoans, bivalves and other oceanic fossils. I do know the majority of these fossils here come from around the Cambrian through the Permian periods, however there have also been a few ice age fossils in the area, so that may help. Thanks a lot!
