  1. Coprolite ???

    Found in northern Wisconsin. I'm new to fossil hunting. Anyway to identify if this is coprolite with this image? I have more photos if needed. Thank in advance!
  2. Yesterday’s finds

    Here’s a preview of what I found yesterday. I went to Wyoming for fossil trip, courtesy of fishdig.com. more pictures coming when I get home.
  3. dino poop?

    Found in Pennsylvanian layers; shale, mudstone, lignite, in Illinois; petrified wood nearby. Is this dinosaur poop?
  4. Coprolite?

    Found on limestone river bank in Alabama. There were fossils nearby (shark teeth, shells, some kind of vertebrae) but not exactly where these were found. Can’t see in the photo but there are tiny gold looking flakes in it.
  5. Coprolite?

    Is it coprolite? Western Ukraine. Age: Cretaceus - Neogene. Thanks!
  6. Coprolite?

    Hey everyone! I was down at a ranch in Southern California looking for fossils when I came across these two pieces below. They look like coprolite to me, but would love some other input. I’m not sure on the exact formation, but I found a lot of petrified wood in the same area. Let me know what you think! Thanks!
  7. Big Brook tributaries

    hello all sorry no photos yesterday was my 19th trip to Big Brook and i decided to brave the elements despite the forecast (actually i look at 2 weather sites and their forecasts were completely different) No lightning and only 45 minutes of rain i have been looking at alternative ways to access Big Brook beyond just the Preserve. Yesterday i hit the Kovalski Tributary and a couple of even smaller streams feeding that. The highlight of my search was my first coprolite. A few shark teeth, crab claws, a fragmocone, and a bone fragment but definitely not good pickings compared to Big Brook within the Preserve. What i found the most of was garbage; metal, plastic and mostly glass and i must have carried out 10-15 pounds. But, bottom line, any day there is a good day. 7am til 12 noon and did not see or hear a single person. Perfect Covid activity. 45 minute drive each way, just me and the Grateful Dead. Just costs gas & tolls . And i get to forget politics or work or any other distractions and be "totally in the moment". Already looking forward to next saturday's trip and daydreaming about the great stuff i will find
  8. Coprolite or concretion or ?

    Good morning all ive never found coprolite as far as I know. I’m wondering if either of these two are. If so, of what and if not, what are they? Note the hair or fiber of some sort in the lighter colored one. As always, thank you for sharing your knowledge
  9. Coprolite / fossil I.D.

    Hello All, Here are a few pctures of some fossils I have found. the first is: 1. Coprolite: these vary in size and slightly in colour. - Country: Australia - State: N.S.W - Town: Cunjurong Point They were exposed on the ground, a clay based ground and there were (Probably still are) hundreds of them exposed. Im curious to know when they might be from and weather it was a dinosaur or an animal more recent. 2. Not sure what this one is? - Country: Australia -State: N.S.W - Town: Somersby This was found while bushwalking through and area where Shale rock was very dominant. Looks like perhaps some type of leaf? 3. Again, not sure what this one is, but its a larger version of the previous one. - Country: Australia - State: N.S.W - Town(Area): Maitland Bay - bottom of a cliff face with many types of rock and mineral, again shale was very present in certain areas. Any help I.D-ing these would be great. Thanks All.
  10. mysterious pellet clusters

    I recently found this coral (I'm calling it Platycyathus vancouverensis until I learn otherwise) at my local site, Mt. Tzuhalem (Haslam Fm, Santonian), with apparently a cluster of pellets inside the 'cup' formed by the septa on the top side. Usually only the rounder bottom side is exposed when I find these corals, as the septa tend to hold onto their matrix. I'll try for better pics if needed, but it's tough! Note that they are all quite small - less than a millimeter. Another specimen that I've had for longer, with septa exposed (more or less), seems to have less obvious bumps or pellets. Maybe the septa have some degree of bumpiness but the example in the first pic above seems different from this:
  11. Location: Missouri Time period: Pennsylvanian Formation: Muncie Creek Shale Specimen 1: Fish Coprolite? 1.8cm (nodule size) Specimen 2: Coprolite? 2cm (nodule size) Specimen 3: Fish Mandible? (2.6cm) Specimen 4: Coprolite or Maybe Braincase (I think it is very unlikely that it is) 2.8cm Nodule size 1.5cm (fossil size) Specimen 5: (2.9cm) Note: The placement of the fossilized material might be wrong as this was one of my first nodules and the fossilized material fell out. I recovered what I could. (Opened roughly 2 months ago) Specimen 6: Tessellated Cartilage with some Skin impressions ? (2.5cm) Specimine 7: Fish material? Thank you for reading and viewing this, I hope I can better understand these images so I can use them as references in the future!
  12. Concretion 6: Fish material

    From the album Muncie Creek Shale Nodules

    My best guess is fish material or crustacean material
  13. Is this a Coprolite?

  14. Coprolite on Matrix - if it is?

    Hello all! I purchased this fossil several years ago, The location given is 'Glen Rose, Texas, private ranch', and was labelled as 'Lower Cretaceous' coprolite on original matrix. I am 90% sure that the coprolites have been lightly stained with a brown stain. I have dozens of legit coprolite specimens from across the Southwest (but mostly Permian and Triassic), but I have never been convinced that this specimen, which definitely has potential for being authentic, actually is. Any insights you can provide would be deeply appreciated. [P.S., this is the 5th of 5 specimens that I'm posting for ID today; I deeply appreciate any insight that you can provide]. With gratitude, Ryan
  15. Everyone here on the forum knows @Nimravis is very generous with his...um...poop. I was the lucky recipient of a Mazon Creek (Pit 4) carnivore coprolite with a very intriguing inclusion. Does anyone recognize this once tasty morsel? Bug bit? EDIT: The scale bar in the photos is 1 mm.
  16. Coprolite, concretion, or scute?

    Hi there! These two rocks were found in the Aguja Formation. Wondering if they could be coprolite, concretions, some kind of scutes (unlikely), or meteorites? Material from the Aguja formation is very foreign to me, so I’m at a loss! They are rounded at the top and flatter at the bottom. Found amongst very large dinosaur bones. Thanks very much! Lauren
  17. twisted rock-could it be coprolite?

    I found this in Eastern Colorado between Denver and Ft Morgan I thought it was mudstone, and had a lapidary cut it so I could see a cross section wondering if it could possibly be coprolite this piece is 5x4x4 inches -12x10x10 cm and if it doesn't show well in the images, it is twisted in appearance
  18. Meteorite or Coprolite?

    Hi there! This rock was found in the Aguja Formation. Wondering if it’s a meteorite, coprolite, or gastrolith? I honestly think it’s a meteorite, but the fact that it’s not magnetic throws me a bit. I don’t know a lot about meteorites though, so would appreciate any knowledge and opinions! Thanks very much, Lauren
  19. Whitby Coprolites

    We’ve seen a few of these things before in shale type rocks at Whitby, could they be coprolites? A couple of other finds from today too; a belemnite with pyrite phragmocone and a nice ammonite that I split
  20. Maryland Coprolite?

    Hi, new guy here. Sorry if this post is all wrong, but here goes. My Mom found this on a sandy beach on the Maryland side of the lower Potomac River. Is it a coprolite, a rock, or something else? Thanks.
  21. Okay, this may be just wishful thinking, but a girl can hope, right? For your viewing pleasure is an Upper Cretaceous coprolite from the North Sulphur River in Texas, Ozan Formation, Talyor Shale. This little beauty has some unusual fish remains. Any chance this is a caudal fin from a coelacanth? The bones are pretty substantial compared to other fish bones I've seen in coprolites from the area. It does contain scales that are good sized and pretty transparent, with kind of a fingerprint pattern. Obviously, they may not be from the same prey item. Can anyone tell me if these are indeed coelacant bones? If so, do they look like those from a caudal fin? Other thoughts? @Fossildude19 @sharkdoctor @Carl Image 1:
  22. Hi Friends, A few months ago I spent a few days’ time on the North Sulfur River and I’ve added some potential coprolites to my collection and wanted to share what I’ve found so that maybe it will help someone be able to identify similar finds there. I picked up anything that I thought looked fossilized and after a few trips I had quite a bit to go through and attempt to identify. Subsequent trips I picked up less and less because I knew what to look for. #1, 2, and 3 are all from the North Sulfur River – Ozan formation. #1 was found in the redzone, while #2 and #3 were found loose in the river bed. I'll start with #1 then add the other two in subsequent posts. #1: Top view #1: Bottom view: This one seemed highly likely to me and has white matrix around lots of black fossilized material contained in the redzone matrix. I happened to tap it after removing it from the surrounding matrix as it seemed like a concretion and found a small tooth inside (orange arrow). I decided to prep it out and find out what else I could discover within. After a few hours picking away through the 'poop' like matrix I had found a vertebra and parts of a shell as well as a considerable amount of unidentifiable fossilized matter. I think I was right about this one. #1: Identifiable finds. Left to right: Tooth, most likely fish., Vertebra, two gastropod shell fragments. Scale marks in mm. #2: Seems likely to me, but not sure. It could just be the remains of a fish or something and not necessarily a coprolite. Top view: Bottom View: More to follow...
  23. @Gizmo and I had a collecting trip cancelled, so we decided to head to Liverpool Point to fill in a few missing species in our collections. Once onsite, we met up with @FossilsAnonymous and @MomAnonymous to do some collecting. There was a lot of sand in most locations, making for a slow but steady day. I found a lovely little Heterodontus cf lerichei early. @FossilsAnonymous was my lucky charm for interesting coprolites. We came across a fairly bare area and I found most of the coprolites below within 10 or 15 minutes. The coprolite below has some scratch marks and possible feeding traces. Its reverse side has vertebrate and invertebrate feeding traces. At least one invertebrate feeding trace seems to have both mandibles recorded. Below are two unusual pieces for this site. They look much more like coprolites found in Virginia Paleocene deposits. Some fish coprolites and possible pseudo-coprolites. Coprolite. Coprolite with compaction visible Coprolite with feeding traces Some lovely orange and grey teeth.
  24. Aloha! Planning a short trip to California before I move further away, I was always fascinated by fossils. Are there any dig sites in California that rent out tools? I would love to find a trilobite or ammonite! Any tips would be greatly appreciated!! Thanks!
