Hey, all! I've reached 1000 posts of the Fossil Forum, and thought I should share one of my small but very cool finds. This is a Vinlandostrophia brachiopod (species unknown), from southern Indiana. It's Upper Ordovician in age, from the Cincinnati Group. I'm not sure which formation it's from, as there are three exposed at the site, and I found it as surface float near the bottom of the slope. It could be either Waynesville, Liberty, or Arnheim. While I have a handful of Vinlandostrophia in my collection, this one is pariticularly cool. Something took a large (relative to the size of the brach) bite out of it, but it survived and healed. This was not a small or simple notch; this was a large part of the shell margin removed. And yet, the critter survived, probably for several more years. There are several growth lines on the healed scar, at any rate. Enjoy!

Hello there! Since the kids are in day camps this week, and my husband was going to see a movie with his friend this afternoon, I took advantage of the available me-time and went for a little fossil hunt at Etobicoke Creek in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician). I have some ideas about what I've found, but I'd like your opinions, too: Specimen #1: trilobite resting place (Rusophycus, probably made by a Flexicalymene) Specimen #2: I think this is the monoplacophoran Cyrtolites ornatus - it was very flaky and some pieces fell off, but I tried to glue together the larger pieces Specimen #3: brachiopod positive and negative, but the question is which brachiopod? Thanks in advance for your help! Monica

Not looking for a full ID, but needing some help. My nephew brought me this piece of gravel containing some flint he found in his driveway, and it looks like on the bottom is a tiny bit of a brachiopod fossil, but I’m not 100% so I wanted to get an opinion here before I told him. Eastern Kentucky region, driveway gravel so I’m not sure of the age/strata or even where it was quarried. Thanks for your time.

Hi, I found these while pulling apart loose shale eroding from the rockface at the Lady's Walk Shale, Scotland. Be interested for any thoughts...! Can upload better pics if needed.

I arrived home last week and after few days of reorientation I managed to get down to prepping the few finds I had made there. There was lots to do with family and friends this time around, but I did manage to get out on 2 day trips. I also slipped out to the Georgian Bay shore at Big Bay for a couple of hours and found this 14cm. long orthocone nautiloid. Don't know what to call it yet, so I'd appreciate it if someone could give me an idea. The stratigraphy is upper Ordovician Queenston Formation. The first day trip was with @Monica and Viola. They took me to Etobicoke and Mimico Creeks in the Greater Metropolitan Toronto area, fed me well with such delicacies as smoked meat and brownies and provided me with enough to drink. I kept my finds down to a minimum, threw a bivalve and a brachiopod in the bag, but I was actually concentrating on finding a half decent nautilus, which I eventually did at Etobicoke Creek. Actually there are 3 of them in the block, one on one side and two on the other. Im calling them Treptoceras until someone teaches me better. This matrix is really tough to prep! I still have another one from MImico Creek which I may just end up sanding and polishing. Here are the two shellfish Byssonchia sp.? Not sure at all about that, but I think that the Brachiopod could be Strophomena sp. Uhoh. Running out of bytes. Looks like I'll have to turn the page to get to Kane.

I found these 2 pieces antiquing in Tennessee (the shell?) and Florida (the coral piece). I realize these pieces didn't necessarily originate in these states...The color of the shell is interesting to me (goldish) and it has some sheen on some parts but not all over. (natural or lacquered?) What does the color tell us? It was in a baggie and simply labeled "fossil". The coral measures 5 1/4" tall. I know it's coral but was wondering if it is fossilized. Any info on either would be greatly appreciated. Fossil? Period? Any other interesting tidbits relative to where I found them, i.e. could this shell have been found in Tennessee? The coral, if a fossil, I'm assuming could have originated in Florida? I think they are beautiful and find them so interesting .

Rhynchonellids are hard to identify by exterior morphology as they often need to have their internal structures visible to be sure of an id. However if you know the faunal lists from a specific area, you can reduce the candidates considerably. The specimen here has 22 costae with 4 on the fold and thus, at this size must be one of two species, Rostricellula minnesotensis or Rhynchotrema wisconsinensis. The only completely safe way to differentiate between the two is the presence or absence of a cardinal process in the brachial valve but this is not possible here. However, Rostricellula usually, though not always, devoid of shell ornamentation, such as ridges or the presence of growth lines, and Rhynchotrema wisconsinensis usually, though not always, shows these, though they can also be seemingly absent through wear. But, R. wisconsinensis never shows a length to width ratio of 1.00, only from 0.80 to 0.95 and this specimen has a ratio of 1.00 which does occur in Rostricellula. Furthermore, the fold of Rostricellula is wider and less sharply developed Finally, good specimens of Rostricellula are far more common than R wisconsinense at the locality as the species most commonly found here is Rhynchotrema ainsiei which is describe elsewhere and not to be confused with the other two due to it's larger number of costae Thus, I am fairly confident with my id

Hi all, I finally found my first Permian age fossils in southern Nevada, however I'm no expert on this age so perhaps some of you could help me out. In general I know what a brachipod looks like but it's really hard for me to tell when looking at these fossils. I'm not sure if the first one is one, or is just some sort of rock.

While scanning some of the fossil plates I found hunting with @Bev and @minnbuckeye, I noticed this little star-shaped discoloration on one of the brachiopods. Anyone have any idea what could have produced this mark?

This past weekend I stopped by Glenerie, NY to look for some Devonian braciopods and gastropods. This was a very cool location as many of the shells, preserved in silica, weather out of the rock complete and ripe for the taking. Thanks @Jeffrey P for suggesting the location! I plan to spend much of this summer exploring the fossil localities of NY and this spot was certainly a great introduction. Here are some of my finds. Brachiopods

Spent a solid six hours in full sun and heat, with biting deer flies, moving rock at my secluded spot. Temps were about 30 C, but closer to 40 with humidity and heat off the rocks. Mostly splitting mid Devonian rock from the Widder Fm. Mostly looking for trilobites, which can be a game of inches... too far up or down in the strata, you get blanks or brachs. First up, a few brachs. These can cluster up in massive beds. The first one was fairly large but I left it there. I did keep the second one as the long tips are fragile and rarely come out whole.

Hi all, Found these two brachiopods by splitting rocks at Cap-Blanc-Nez in France. Most fossils there are Cretaceous in age, but these were found in greyer rocks that felt more like clay than chalk to me. I suppose that means they are from a different layer...? If so, what would the age be (stage)? Anyways, what species do you guys think they are? Thanks in advance! Max Brachiopod #1:

Hi all, Just wondering how I should go about with the prep of this one. It's from Cap-Blanc-Nez, France, and the matrix is Cretaceous chalk. Should I prep this using vinegar (and water)? If yes, how? Or is it better to go with the small metal picks? (The matrix is rather soft) Any other tips or things I should know before I tackle this one? Thanks in advance, Max

Today I received a special surprise at work; our magazine editor found this fossil in her yard! A nice brachiopod, it seems! Here are the two mysteries: 1. WHAT TYPE of brachiopod? (I'd be happy with FAMILY). 2. FROM WHERE? I was excited that she had MARINE FOSSILS on her land... but she said this was in a bunch of rock THEY BOUGHT for landscaping purposes. ANY ideas? I have seen nodules like this from out west - Any opinions or guesses welcome!

Hi everyone, I am a longtime lover of fossils and natural history, but I never did any real fossil hunting until very recently. I took my son to a road cut in upstate NY (Rickard Hill Road in Schoharie) that has tons of Devonian fossils. The attached photos show two of the fossils, one of which appears to be a small brachiopod, possibly the one at the bottom of this ID page: http://bingweb.binghamton.edu/~kwilson/Devonian/DevSites/Schoharie/Becraft.htm I have never done any type of fossil prep, and I am wondering how to get started, particularly with specimens like these. I collected a few larger pieces that have dozens of brachiopods each (they were pouring out of just about every rock in the area), so I have something to test techniques on before working with the more intact/better preserved pieces. Any recommendations would be appreciated! Thank you, Steve

I'm pretty sure it's a brachiopod. After that, I'm lost. I have a book that I'm using, and it matches a picture of a Torquirhynchia, but it says those are found only in Europe. This one was found at the Trammel Fossil Park. http://drydredgers.org/fieldtrips/trammel_fossil_park.htm I don't remember in what layer I found it. Side note, here's a close up of the tiny fossil next to it.

Can anyone help ID this shell? It's from the Pennsylvanian Pottsville Formation near Cordova, Alabama. Size is about 3/4 to 1 inch across. Found in a layer of shale with lots of plant fossils.

I collect in Coralville Iowa frequently and always run across these brachiopods. Yet I am unsure of their name in spite of investigation on line. They are NOT uncommon so the ID should be easy but eludes me. So here I am asking for assistance! They are flat as a pancake if that helps.

Hello everyone! This past Saturday, Viola and I braved the cold to do some fossil collecting in the south pit of Hungry Hollow near Arkona, Ontario (Mid-Devonian). When I got home and washed up my specimens, I saw something interesting on one of the horn corals - I think it's a brachiopod - am I right? And does anyone know its identity? Thanks in advance for your help! Monica

Hi guys, new to fossil hunting so I thought I'd ask for some help identifying a few fossils my girlfriend and I found at a park near Louisville, Kentucky. We found a ton of brachiopods among the creek gravel, almost completely without context, but this was the only one intact and in decent condition. Is this what I think it is, a Vinlandostrophia laticosta? According to this resource we're only about 30 miles or so out of its documented range. http://www.ordovicianatlas.org/atlas/brachiopoda/rhynchonellata/orthida/platystrophiidae/vinlandostrophia/vinlandostrophia-laticosta/ Thanks!
