  1. Almerarhynchia virgiliana

    New genus and new species first described by Dr. Sebastian Calzada Badia in: C a l z a d a , S., 1974. Almerarhynchia n. gen. virgiliana n. sp. del Maastrichtiense de Figols, Prepireneo catalan. Acta Geológica Hispanica, 9 (3): 92-97. http://digital.csic.es/handle/10261/7365. ID of the specimen confirmed by Dr. Calzada.
  2. Waconella wacoensis question.

    I found all 3 of these in the Grayson Formation in Tarrant county. I know the smaller ones are Waconella wacoensis brachiopods. I assume the larger one is the same, but I wanted confirmation that it is also a Waconella wacoensis. I may have found one other almost the same size, but this one is more that twice the size of the other two. The brachial valve view. The pedicle valve view. I The sizes of each one in the last 2 pics left to right. 25 mm long x 20 mm wide x 16 mm thick 16.5 mm long x 16 mm wide x 10 mm thick looks like it may have been crushed in on one side so that increased the width and length some. 16 mm long x 14 mm wide x 10 mm thick Can anyone confirm or rule out that they are the same?
  3. I found several pieces of the obviously the same brachiopod species in one site (so they are from the same colony, maybe even the same family) in Yuangquan of Shanxi province, China( known for CP fossils) the ventral shells seem to be double layered, with clay in bewteen now . This is true for all three piences, but more discernable in the last two ( as shown with circles). In the first piece the outer layer remains are stripped to reveal a complete outlook. I knew nothing about brachiopodes. But from the literatures I could get hold of, there is no description of double shell.
  4. Brachiopod from Canada

    Hey everyone, Nearly forgot to post this little beautiful dude in the Fossil ID section. I got this as a gift from the Geo-Oss fair some time ago. The only info I have on this little spiriferid brachiopod is that it’s from Canada. Now, this is probably a long shot, but I was wondering if anyone maybe recognized which location, formation and age correspond to this little dude? If the species is also recognizable that’s awesome. There were a LOT of the spiriferids in that box, all seemingly of the same species, so it’s a location at which these brachiopods are common. Anyone have a clue? Maybe one of you guys @Tidgy's Dad @Wrangellian @Peat Burns? Thanks in advance! Max
  5. Hey all! First time poster. Found a few fossils along the Milwaukee River in Milwaukee, Wisconsin. Looking online, it appears this area was a Devonian Reef. I don't have a lot of experience in fossils besides plants, so any ID or commentary is helpful. A few of these I just found as pieces in big piles along a rock formation, I tried to put up a ruler for scale. For the one piece in situ, I didn't have anything handy, but it wasn't more than a few cm across. Thanks!
  6. Serpulid i.d. needed please

    Although probably to water worn for a positive i.d., I think this brachiopod may be Obovothryris magnobovata which I found in some Bathonian Cornbrash Formation exposures. What id like to know if possible is the age and specie’s this Serpulid tube would be in relation to the brachiopod.
  7. Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella?
  8. I found this little rock in a creek in middle Tennessee. (Mississippian, St. Louis Limestone & Warsaw Limestone) I know there is a brachiopod and bryozoan in it, but am wondering if the area circled in red (last picture) is also a brachiopod, or something els?
  9. Rockford, Iowa fossil sites?

    Any fossil sites around Rockford, IA other than fossil park? Want to hunting with my kids for a while. What about fossil sites between Waterloo, IA to Dubuque, IA?
  10. Waterloo

    Any fossil sites around Waterloo other than fossil park? Just curious as I'm not from around.
  11. Hi, can anyone lead me on determining this species of brachiopod? This brachiopod originates from the Reynales Formation, Clinton Group of Hamilton, Ontario from the Niagara Escarpment. A name I found for this shell is Stricklandia canadensis when I was reading a document about the Escarpment, though when I went to the fossiilid.info and the fossilworks websites there is no mention of the species. I began to think this could be a Stricklandia lens. The shell in the centre is approximately 4 cm long.
  12. Found on Presque Isle. What is it?

    Thanks to everyone who suggested better pictures in daylight. Done!
  13. Found on Presque Isle. What is it?

    Found this in beach at stone breaks 21 and 23 on Presque Isle, PA (Lake Erie) today. What is it? I am new to this!!!
  14. Insane Brachiopod

    Hi all, I recently saw this very cool, but also very expensive fossil brachiopod. And well it may be a little out of my price range I would still like to know if it is legit. The seller states it is an undescribed brachiopod that has affinities to the genius Echinaurus. It is from a layer several meters above the Drotops couche at Mrakib, Morocco. This area is Middle Devonian. The seller states that it is about 3.33 inches wide and that the white mineral on the brachiopod itself is natural, not glue or anything like that.
  15. Hey, all! I’m planning a trip to England’s Jurassic Coast next summer. I’ve researched areas like Dorset, Charmouth, and Lyme Regis. I plan to hit all these in my time there. Any other recommendations or information I should know? I’m excited to explore the area and collect some new fossils!
  16. Part three to my safekeeping series. These are some of my finds from the middle Devonian Mahantango Formation of Maryland. Unlike the other formations I posted about, this one is pretty well known for it's fossil contents, so I will keep the introduction and background brief. For those who don't know the Mahantango is a middle Devonian aged marine shale that's part of the Hamilton Group in Maryland. For the most part it's fauna is dominated by brachiopods, but occasional gastropods, tentaculitids, and other animals show up as well. It was deposited in a shallow inland sea with the depth of the sea varying over time. This is only a small fraction of what I have, but it's some of the best. Image 1: Spiriferid brachiopod, Mucrospirifer mucronatus? Image 2: Some odd fragment (possibly trilobite related?) with a M. mucronatus. Image 3: M. mucronatus.

  18. 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! Brachial and Pedicle Valve views Hinge and Aperture views Normal and Pathological side views
  19. 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
  20. Possible brachiopod

    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.
  21. 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.
  22. 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.
  23. and a productive trip off on Kentucky 17 in Northern Kentucky any location that exposes the McMillan formation. Fossils fossils in this ordovician exposure are about 445 million years old
  24. My first Permian Fossils

    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.
  25. Let's talk brachiopods!

    Hi all, I don't know much about brachiopods beyond general recognition. Since I found that little unidentified echinoid(?) I have decided to prep some of the loose brachs that I found on a recent trip to Fillmore Co., MN. The complete brachiopod here appears to have been attached to another brachiopod shell. So here are my questions. 1. Can anyone identify the brachiopod? (I am assuming they are the same species) 2. Would this be considered an unarticulated brachiopod? 3. I haven't finished prepping the interior of partial brachiopod. I wasn't sure what to call it so I referred to it as the host shell in the photo. It has what almost looks like an open crack. Any idea what might have caused this? There are little black specs surrounding it. Could this have been caused by another brach pedicle? When I was prepping it, it kind of reminded me of a burrow lined with tiny fecal pellets - but my imagination does tend to get the best of me. As always, thanks for your help! @minnbuckeye @Bev @Tidgy's Dad
