  1. Unknown Brachiopod

    Unknown brachiopod, looking for an ID. Any & all help is appreciated!
  2. This weather has got me a bad case of cabin fever, my normal fossil hunting ground along the Whitewater River in Southeast Indiana is flooded. Went out in my back yard today to look thru the two truck loads of leach line gravel I bought for landscaping, the quarry is only about a 1/4 mile away. Found this odd ball, thin layers of crystal like formations on both sides, has hollow cavities and some brachiopod fossils that are a red color. Just curious as to how it formed, wish I could get closer photos of the brachiopods, will try again tomorrow with some daylight....if the sun ever shines again LOL.
  3. Brachiopod

    Found these in Emmitsburg, but the lake was supposed to be fresh water?
  4. Show us your favorite brachiopod fossil in your Collection!
  5. What kind of Brachiopod is this?

    I found this brachiopod as float on the side of the road. It was very near the transition of Devonian to Mississippian Lodgepole Formation in Little Belt Mountains, in Montana. The fossils is large. I'm thinking it might be a spiriferida.
  6. I've been preparing some things from the Late Jurassic Kimmeridgian for a friend, including a number of Colosia zietini brachiopods. Particularly after they were abraded, I noticed a lot of tiny circular forms on all of them and now I'm wondering what their origin might be, whether mineral or organic dissolution phenomena or whatever? I'm thinking maybe some little things had been attached? Or are they mineralogical? Any ideas?
  7. Greetings. I chanced upon this in the way out yonder in a Pennsylvanian formation while out on a hike...and wondered to myself 'Self, is this a brachiopod with a quartz crystal lophophore or a brachiopod with some quartz crystals in it'. Time to ask the pros or those in the know...
  8. I was traipsing around in a wild geologic zone 'red ellipse'. Lots of faulting, etc. I was in the orange area when I found a block of what could pass for recently dried mud having quite a few tiny brachiopods about 5mm in width. Maybe the brachiopod lovers could help put a generic name to this one so I can do more research? There are some larger brachiopods of a similar appearance (yet different) on the specimen but the largest barely gets to 10mm. I will post additional pics tomorrow when I get better lighting.
  9. what are these circles on this brachiopod

    I have a strophomenata brachiopod with small circles and what look like puncture holes in center of circles. What may have caused these?
  10. I've found a blob me thinks. Came across this on the Whitewater River, Southeast Indiana. What the heck do you think is in this? I see a Leptaena.
  11. Leptaena

    I collected this Leptaena brachiopod from the red brown mudstone resting three feet above the top of the first out crop of breccia limestone. The location is above the rest-stop on highway 89 S before Riceville Rd. The formation is the lower part of the Kibbey. Leptaena Brachiopods dominate along with three types of bryozoa and crinoids. Also found clams and a part of a plant fossil. The setting was once a lagoon.
  12. I found this conglomerate, or hashplate of Brachiopods on the Whitewater River, Southeast Indiana and wonder what they are. It seems like a cross cut of the ancient Ordovician sea bed because all the fossils are on top of rock that seems layered. I've been slowly working on my first prep, from left to right using sewing machine needles, I don't want to mess it up!
  13. Ordovician Brachiopod Id?

    I found these brachiopods on the Whitewater River, Southeast Indiana within the Cincinnati Arch. Was trying to identify them with my book wondered if they are what I think they are. The one on the left, the shell with the groove in the middle, could it be Platystrophia? The small shell bottom right, Hiscobeccus? The cluster of shells on the top, I have no idea. I appreciate how help you all are!
  14. Hello to everyone, I was trying to put together a plan for a spring or summer trip hunting fossils. I am particularly interested in the animals of mahantango formation and would like to know if anyone is familiar with some public locations that allow people to hunt for the fossils from that formation, or at least do not prohibit this. If anyone can point me in the right direction that would be greatly appreciated, Thank you.
  15. Michigan rest stop

    Just beforehand my exit on the highway, I really needed to use the restroom, and pulled off at a rest area. This was quite lucky, since there was a very large piece of shale sitting in front. The whole thing was a giant hash plate. It was heavily weathered though and there were a bunch of fragments strewn around. I ended up finding quite a few nice pieces in the debris on the ground. Here's the rock and a closeup.
  16. Silica Hills, TX

    Does anyone know if there is anywhere to collect brachipods and other inverts in the Silica Hills of West Texas? I am a geologist who used to live In Austin, TX (20 years ago). I recently asked some colleagues who did hydrogeologic and geologic fieldwork in west TX, but have not gotten any leads. They say all(?) on private property. This is a bucket list trip for a buddy of mine!!!
  17. Gerster Fm. Productid Brachiopods

    This particular species had spines attached to the shell which is not all that common. There are four spines attached on the thumbnail brachiopod. The holes in the shells were where spines used to be attached. Found during this trip here:
  18. Acrothele subsidua

    Found associated with Elrathia kingii and Itagnostus interstricta trilobites. See field trip report here:
  19. 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.
  20. 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?
  21. 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.
  22. 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
  23. 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!
  24. 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.
  25. 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?
