Orbiculoidea capuliformis with preserved pedicle, Muncie creek concretion
Jaybot posted a topic in Member Collections
I recently collected some Muncie creek concretions from the Kansas City area. I had previously only found a few concretions, but this time I was fortunate enough to end up with about 10. Several had Conulariid sections preserved, which I was excited about. Back home, I cracked open the remaining concretions. One of them had a tiny little brachiopod, and I didn't think much of it. Later, looking at it under magnification, I was astounded when I found the remains of the preserved pedicle! This is where I am sad to say, that in my excitement, I forgot to take pictures of the fossil prior to me prepping around the shell to aid in id. Anyways, after prepping around the shell with a hand scribe, I was excited to find that it was also my first lingulate brach. Orbiculoidea capuliformis Sorry for making you read all of that, here are the photos: Scale is in cm. Here are several interesting articles/papers for anyone interested. https://www.diva-portal.org/smash/get/diva2:373816/FULLTEXT01.pdf https://www.researchgate.net/figure/a-b-The-brachiopod-L-chengjiangensis-represented-by-stout-pedicles-marked-by-numbers_fig1_24424671 Despite being small, there is a lot of potential with Muncie Creek shale concretions. I learned a lot about them, and their existence, here on TFF. @Missourian has found many astonishing finds, and I noticed that soft tissue preservation is prevalent in many of his best concretions. Hope y'all enjoyed this. Have a great day, and a great weekend -Jay

A question about the brachiopods Paraspirifer bownockeri
Misha posted a topic in Questions & Answers
Hello everyone, I have been wondering about this for a bit but only now that I atually have one of these in my collections have I decided to ask this, All of the P. bownockeri I have seen have been pyritized and I wanted to ask why this is, I do not know of any other brachiopods like this because while there are some I have seen preserved in pyrite they are from areas where the rest of the fossils are also pyritized, from what I have seen its mostly just this species that is commonly found fully pyritized from this formation. The only thing I can think of is maybe they are found in a specific layer which is why they are the ones that are primarily pyritized. So my question is, what causes this? Also do these brachiopods come preserved in other mineral such as calcite? If anyone knows or has any useful sources I would love to hear it! Thank you very much, Misha- 7 replies

I received this Brachiopod from my parents a while back after they took a trip up to Boston (this was before I started fossil hunting) and as I noticed it in the forgotten back corner of my display case yesterday I realized I could probably get an ID on it. Unfortunately as it was bought from a gift shop I have no locality of where it's from, or the age, but hopefully we can make due and get as close as possible, thanks! (3.1 cm corner to corner)

This was found in the Carboniferous limestone of the Malahide formation , east coast Dublin Ireland,, i preped out this fossil in layers as i only had half of the outer shell to start with but i am confused with that bottom layer, hope somebody can explain it to me , probably @Tidgy's Dad

Sea urchins, sand dollars and brachiopods, Aireys Inlet, Victoria, Australia
Oli_fossil posted a topic in Fossil ID
Hi all, See attached - most of these are 5-10mm in size (cm/mm ruler in background). Found at/near base of sandstone cliffs near Aireys Inlet, Victoria, Australia. I have previously found Lovenia fossils in the area (and found a couple more today), but these are much smaller and flatter - more like sand dollars? IDs appreciated, and also suggestions re further cleaning - I just soaked them in water (~30min) and tried to remove loose material, but haven't done anything further. Would it be worth soaking/cleaning them further to try to remove more matrix? Also, do you think the small spines/tripods in 2a/2b/23c are the original spines of the sea urchin? I think 4 is probably the top lid of a similar brachiopod to 3/3a - does that seem reasonable? Cheers & thanks in advance, Oli

I have a lofty goal to collect at least one species of every brachiopod found in the USA that I can possibly obtain. I recently started a spreadsheet to itemize my collection. Spread sheet is attached. I will also periodically add photos. So far I've added: Cambrian, Silurian, Devonian, Permian, Triassic, Jurassic, Cretaceous, Paleocene, Eocene, and Pliocene Brachiopods of the USA.xlsx

As I've been cataloging my Devonian finds, in my research I've come across both mucrospirifer and mediospirifer. I'm not certain of the characteristics that would set the two apart. Can anyone provide some clarity or point me towards a resource that could?

Distinctive Permian Brachiopod from Arctic Canada
Brachioman posted a topic in General Fossil Discussion
This nice Permian Brachiopod has a very large apsacline ventral interarea and is called Arctitreta triangularis. It is from the Assistance Formation in the Artinskian of Devon Island in Canada. It is related to Schuchertella and the more common Streptorhynchus. Does anyone else have any interesting Brachiopods from the Permian?

Microtrilobites and Other Microfossils of the Pooleville Member
Isotelus2883 posted a topic in Micro-paleontology
Recently I acquired some microfossil matrix from the Bromide Formation, in Oklahoma. They were of the Pooleville and Mountain Lake Members, containing a very diverse fauna, mostly bryozoans and crinoid arm fragments. While searching through the matrix, my main aim was to find some of the small and young trilobites that are often found here. Also, I had bought a trilobite meraspis previously, from the same locality. It is an enrolled meraspis of a Lonchodomas mcgeheei, from the Pooleville member. Views of the Cephalon and pygidium.  Now, here are the finds. A Cyclospira parva, these were very common and found in all samples of the Pooleville Mbr. These are the trilobites of the Lower Pooleville. What may be a partial Lonchodomas mcgeheei pygidium. It is more likely a brachiopod fragment, however. A proetid free cheek, I think. This one is more likely to be a Homotelus bromidensis cheek. I'm not sure for this cheek. Eoceraurus? Here are the trilobites of the Middle Pooleville Member. Calliops armatus partial pygidium.It is rather fragmented, as sadly most of the microfossils in this material are. This may be a trilobite pygidium, but it seems now that I look at it, it may be a brachiopod. Now here is one of my better finds from the matrix. It is a partial trilobite, with the hypostome in place, unusually. Because the dorsal side is not preserved, I don't know what species it is. Here are the fossils of the Upper Pooleville Member. A picture of some of what I found in the sample. A healthy sized proetid free cheek. Two partial cephalons of Frencrinurus capitonis. Though partial, they still show exquisite detail, including several sharp spines. Last, there is this specimen. I am hoping it is a protaspis of some trilobite, but... Yeah. Doesn't look like it. These samples gave a clear picture of the Bromide Formation, and they were rich with fossil fragments, an excellent test for my microscope.
