Last weekend I had the opportunity to spend a few hours collecting in a quarry in northern Illinois that exposes most of the Galena Group (Late Ordovician). There was lots of fresh rock to hunt through, and it was a good and productive trip. As usual, lots of gastropod molds were found. Hormotoma sp. Liospira sp. Sinuites sp. Lophospira sp. Subulites sp. Unknown gastropod. Looks like Liospira but appears to curl in the opposite direction. Brachiopods show up too. Most common are molds of what I believe are Rafinesquina (@Tidgy's Dad?). The inarticulate Pseudolingula iowensis is somewhat common. Specimens are almost always crushed and missing shell, but they usually have some shell preservation which contrasts nicely with the yellow matrix. Occasional bivalve molds are found. This one has calcite? crystals. Trilobite parts are uncommon, and the only species I've seen from this quarry is Thaleops, possibly Thaleops laurentiana. Here is a cephalon I found. Now for my favorite finds of the day. A partial specimen of the small receptaculitid Ischadites iowensis. Fisherites is very common at this site, but I had not come across Ischadites before. A partial conulariid. Judging by the visible cross section, the back side is present, so this should hopefully prep out nicely. And finally, what might end up being a complete trilobite. Not sure if there is any more buried, but it does look like at least some of the shell is preserved, so fingers crossed!

I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

IDing my Waldron Shale finds is going well, but I hit a snag when getting to Atrypa. My research shows Atrypa reticularis is a common brachiopod found in the Waldron. Also mentioned was Atrypa newsomensis, for which I could not find a picture or description of. My finds include what look like two different Atrypa species but could be the same. There are smarter members than I that hopefully can set me straight on this. The first specimens are what I feel are Atrypa reticularis. The next group are much more ornate. They remind me of Spinatrypa beulla of the Devonian.

Hello, I am new to fossil hunting and identification. I took this fossil to a mineralogical association meeting last night and no one could identify it. Hopefully someone on this forum can. It was embedded in a rock I found on the shores of the northeastern section of Lake Michigan. The other side of the rock has a brachiopod in it. I removed this from the rock using a dremel engraving tool with a small chisel attachment. That is what made the surface marks (but not the deep divots). Can anyone help identify this thing? Thank you! Windwalker

I acquired this specimen from fellow member @Brian James Maguire, who collected and polished this beautiful piece. The colors are outstanding! Thanks again for the amazing addition to my odd brachiopod collection.- 2 comments

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- 9 replies

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
