Howdy! So I was out in West Texas this last weekend trying to hunt down some new echinoids (will post those later!) but i came across some odd looking brachiopods. I am 99 percent sure the formation was Buda (it's kind of hard to be certain as I am no geologist -but that is what I pinpointed on the Texas Geological map, but I might have been at the wrong roadcut, too). The other fossils I found there were Texigryphaea and Neithia texana. I am familiar with the Brachiopod Kingena wacoensis in the Georgetown formation of Central Texas Cretacous. I wasn't sure if Kingena is found in the Buda formtion for one thing. A second thing, these look very different than Kingena. These have a "dip" in them more like Pennsylvanian brachiopod Composita. All the other Kingena I have found are straight "lipped". Any help would be appreciated!

Hello everyone, I am looking to get some more definitive IDs for these finds from the Lower Devonian Kalkberg Formation in NY. I have some idea for what these guys might be but I would like to see other opinions from the forum before I start labeling them. I will post more brachiopods as I take and process pictures, but here are the first few: 1. I believe these are three might be Rhipidomella

Exploring Paleozoic Sediments in Southern Utah
Sagebrush Steve posted a topic in Fossil Hunting Trips
Just before the pandemic locked everything down, I went on a geology hike near Comb Ridge in southern Utah with Professor Gary Gianniny, Chairman of the Department of Geosciences at Fort Lewis College in Durango, Colorado. I’m working on a book about the canyon country of the Southwest and this was a great opportunity to learn from an expert in its geology. While the hike primarily focused on geology, you can’t tour this region without seeing fossils. All our fossil collecting was catch-and-release. I took photos but did not bring back any physical specimens. Here’s a quick overview of our hike. We started from a point on the southeast side of a feature called the Monument Upwarp, about 16 miles west of the town of Bluff, Utah. Here is a Google Maps satellite view of the area: And here is an aerial photo I found on the Internet here showing where we hiked (the lower left corner). Comb Ridge is the 500-foot high escarpment at the top right of the photo running north to the horizon. Comb Wash is the gully just to its left, and the San Juan River is on the lower right. Our starting point overlooked an abandoned meander of the River, just off the left side of the aerial photo. The river long ago took a shortcut by punching through a narrow wall of the meander (out of site behind the near slope), leaving it now abandoned. It reminded me of a gigantic, empty baseball stadium: From there, we turned east and went down the side of cliffs bordering Comb Wash. During the first part of the hike on the top of the Monument Upwarp we were in the Honaker Trail Formation, a marine limestone of the Pennsylvanian Period. Gary has done quite a bit of research on these limestones. He pointed out numerous examples of fossils in this formation. The first was a brachiopod (I didn’t get the species). Notice the spring-like squiggly lines along the hinge line at the top. Gary said these are indicative of it being a brachiopod: Here is an example of crinoid pieces. Gary said this limestone is made up of about 90% crinoid fragments: And here’s an example of a clam (again, no idea of the species): As we descended, the layers got younger because of the way they were tilted (you can see this by studying the aerial photograph). When we got to the red layers, Gary explained we were now crossing into the Halgaito Formation, terrestrial sandstones of the Permian Period. He pointed out fossils of plant roots encrusted in calcium carbonate (the light gray areas). These are called rhizoliths. He said you can still see rhizoliths forming today on the roots of modern plants. Gary went through a lot more about the geology of the area, but that’s about it for fossils. Like most geologists who frequently get out onto the landscape, Gary was in good physical condition. I however, was another story. The 600-foot return climb across gullies, boulder fields, and loose scree was about the limit of my sorry physical condition. But it was a great experience and one I wouldn’t hesitate to do again.

This fossil was found by an old friend of mine in maine, and I need some help with the ID on it. All i know is that it is from maine and that it is a brachiopod (the largest fossil present)

At our camp near a gully in wellsboro, PA, I spend my time fossil hunting. I find thousands of common fossils in a variety of rock. This time I found this cluster that doesn't look fully fossilized. Any ideas what would cause this appearance?

Last weekend I decided to take a short drive to Vermilion County, IL and get outside for a little bit. I haven’t been able to do any fossil hunting since COVID-19 reached our shores, so I had a few iffy sites less than 40 minutes from home in mind as I was driving. The first two proved fruitless, but I decided on a whim to take a new road over a local river in hopes of finding some exposures there. The river was running high with verdant growth all around and dragon and damselflies filling the air. As I looked down from the bridge I saw sandy shore, concrete bridge abutment, and then a small section with some intriguing rocks scattered along the river’s edge. Once I made my way down to river level, I found that the black rocks visible above were pieces of black shale and coal. I was excited! I had been thinking of black shale since collecting some on an ESCONI trip last year and reading @connorp’s posts about black shale finds. This shale was much more fragile and bedded than the Mecca Quarry Shale I found last year, so I was able to split it easily by hand. I was too excited, so I forgot to take any in situ photos (I took the ones above on my way back to the car). Before too long, I spotted the unmistakeable shape of a dermal spine from the iconic black shale chondrichthyan fauna Listracanthus hystrix- a strange shark relative covered in spiny denticles. I spent about 30 minutes searching this small exposure and turned up several more Listracanthus, the inarticulate brachiopods Lingula and Orbiculoidea, fish scales, and some mysterious spine fossils. Unfortunately, almost everything was tiny (less than 1 cm) and I don’t have a macro lens for my phone yet, so photos of most of them will have to wait. Here is everything I kept after trimming the matrix down: I will share some more pics of the best Listracanthus in my next post.

I found these and am wondering if they are brachiopods, or just bivalves with symmetrical valves, as I have not yet found a brachiopod in this location yet. Sorry the photos are dark. Many thanks.

What are these and please don’t say they’re concertina

Hi! A find from Devonian in central NY, Tompkins county (USA) again. Am I right with the following guesses? 1. Spiriferida (Mucrospirifer?) 2. Atrypa Thank you! I see often that a mold of a fossil is more clear and has more features than the corresponding cast. Is it usually the case or the feature if the rocks that I find? Is there a way to clean it to make the cast more visible or the features are lost already (e.g. #1 of the picture)?

Kiowa formation and Albian. Approximately 1.3cm long and its quite flat and thin. Not sure if it's brachiopod, more specifically a lingula brachiopod, or a bivalve. Unfortunately the umbo is missing so I'm not sure if it's symmetrical or not. I'm leaning more on bivalve but I would like to read your opinion. What's the lowest taxonomy level you can identify?

Trematospira perforata from the Exposure of the Kalkberg formation along Rickard Hill Road in Schoharie. -
I found this brachiopod today in Schoharie, New York. Its from the Lower Devonian Kalkberg formation and it’s by far the best brachiopod I’ve ever found. It’s super detailed and it’s absolutely perfect (except for some matrix that still needs to get cleaned off). I’m unsure of the species so any help would be great.
