  1. Cameloid skull and ramus- NE SD ?

    Whew. Last one with identifying marks to identify. Is a museum cast. UNSM 4616 Sure, I could email the collections curator at Morril Hall, but I’m afraid to wear out my welcome. As of yet have been unable to find data on this one on my own. Figure I’ll give yinze a crack at it before I bother the museum for the twentieth time. My research shows this to be a camel of some sort. It is likely Nebraska or South Dakota in origin for the original due to the provenance of the other casts yinze have seen me dealing with the last few weeks. This is a pretty poor cast with lots of missing parts broken off from poor storage. In fact, it is so bad I’m considering doing a full on arty reconstruction as it is not suitable for display or education in its current form. Due to the pigmented plaster, it does not photograph well. Cannot find a single reference to this number online. ( doesn’t help there’s a wristwatch and a snake fossil with similar ID numbers) Any ideas? I really want to finish ID of these casts so I can focus on real fossils!
  2. Fast and dirty: Found this cast a day or two back in the stock room- someone made an attempt...so I’m going to fix it since it uses similar colors to the lion and peccary projects.
  3. Skull cast prep- porcine

    I was able to get an exact ID on this American Museum of Natural History cast...which I promptly forgot on a Post-it on my desk at work... so posting now as this is the next attempt at museum quality display prep. will update the ID in an edit...can remember it’s a cast of the type specimen from the Sharps formation. Porcine. for this one I plan extensive reconstruction to make it better than found!
  4. Will follow up with current stage photos shortly! Here is what I started with: Unidentified Provenance Unknown Really bad mold mismatch/ thick seam
  5. need help identifying this

    I went camping today. ok, not really camping. just picnicking at a campsite in the woods. we didn't stay over night because it is far too cold. so I found this rock with these cool indentions and want to know what it is. at first I thought it was by a tool but it's not. thanks, dorky
  6. Basement recovery part 2 Reptile Replicas?

    Part 2 of my Fathers basement I have 2 crocodile skulls and one turtle. I believe they are Replicas? but the teeth on the crocodile are Fossils? once again I believe these are out of Morocco in the 70s or 80s? Thank you
  7. tubular trace fossils ID?

    New to geology, so excuse my paltry terminology. Description: Tubes, many branching, between 1-3cm in diameter, in places as thick as a forest root system, material very sandstone-y, surrounding material clay. from my research these seem like burrow casts of... worms? tetrapods? do burrow casts form in such abundance?
  8. Hi I found this with the rest of my fossil replicas and was wondering if it could be a Rex tooth or another type of Tyrannosaur tooth. I don’t know if I can post this here or get an ID on it since it’s a replica but I got it at the Royal Tyrell Museum in Drumheller, Canada it’s a replica of one of there specimens. And I just wanted to know what it could be since it seemed strange to me on how skinny and long it is, Thank you!!
  9. What is this called?

    I know it’s a internal cast of something but I can’t remember what.
  10. For those that don't live and breathe fossils like we do, horn corals are often mistaken for horns, claws, etc. I knew someone who even swore the horn coral he had found was a fossil carrot, despite my insistence to the contrary. So after finding my best horn coral specimen ever (the largest one in this trio is about 9 inches long), I decided to make a cast of the specimen and "reconstruct" it to show people what they may have looked like when living. I know @caldigger will be very happy that there is now a horn coral action figure - complete with bioluminescence! Fossil next to "reconstruction" "Bioluminescent tips" @Bobby Rico, @Tidgy's Dad, @Nimravis
  11. Unknown Limestone Fossil

    Possibly a burrow? Found beneath the Chinle formation on US89 in northern Arizona. 4 inches long, 2.5 inches tall, with a slight curve and a flatter bottom side. The rock looks like limestone, but was found on a flat wash without similar rock in the nearby area.
  12. Strange Preservation

    Here's a strange one. I found plentiful piles of what I thought were casts and internal molds in the iron-rich St. Mary's clay of Virginia last year. Loose clam fossils riddled blocks of talus. I was able to wiggle some out of their ancient resting places without s much as scratching the matrix. Generally that's because the shell disintegrated, leaving a void between the mold and the cast. If you look closely, however, what looks here like an internal mold isn't. The sculpture on the surface is clearly the outside of the shell. If it were the inside, you would see round protrusions where the ligament attached to a depression in the shell, not concentric ridges. Shown here is the most distinct of my specimens, but not the only one. Any thoughts? Mercenaria campechiensis, Miocene, VIrginia
  13. More Massachusetts Fossils

    I found these two today, looking for identification
  14. Tiny worm casts or teeth

    My last inquiry, as found in clay stone/mudstone @ Savannah River
  15. Mosasaur skull cast

    Hello evereybody, I dont know if this is the right place to post this but I would be interested to learn more about mosasaur skull three-dimensional anatomy. Do someone know where it is possible to buy accurate mosasaur's skull cast? I am looking for something more educational than decorative and ideally not too big. I know that there are plenty of interesting stuffs on the web but from my experience in human medecine nothing is as good as a three-dimentional model to understand complex anatomical structure like the skull. Thanks for helping!
  16. So, I found this guy on the auction site, really only this one representative photo. These are often fake or frakenfossils, but I didn't see anything that screamed fake to me in this one photo. Just wanted to put it out to the room for other people's input. It doesn't matter as I basically stole it for 9$, so even if it's fake, I don't much care. Just curious what everyone thinks. (I don't have more photos, I just bought it this morning, this is just the provided photo. I'll be able to tell if it's fake when it arrives this weekend for sure, but the suspense is just too much, lol.) Also, it's about 5" long, not that that matters.
  17. is this a clam cast???

    While I was out cracking that last rock I found this in the drive is this a clam cast??? found in my drive from a gravel load west oh Houston Texas from Brazos river
  18. This supposed real Cretaceous croc from Khourigba, Morocco is up for auction and, uh, isn't this just a painted cast with some real croc teeth thrown in?
  19. rapp creek hunting

    Howling wind and deep ice cold water, but figured the creek bed would protect me from the wind (it did) and cold (not so much). Less hunters out. Don't usually post casts/steinkerns but this gastropod(?) has two small fossilized worm like things on it (probably need to get a better photo than the scan). All the rain has washed shells everywhere (lots of 5" to 7" scallops/ pectans everywhere; didn't see any whole ecphora, the only shells I usually pick up. Frilly oysters were everywhere as well; top half is neat). Most of the teeth I found was small or broken or both; three cow shark, one decent with root. Four(?) angelshark and several others, lots of spikes most missing their cusps, small triangular most with faint serrations, and a bunch of glossy drum teeth (photo is of the other side). Broken verts. When other stuff dries, may find something else interesting.
  20. Cast of what?

    I picked this bit of oyster shell up because it has pretty barnacles on it. I started cleaning mud out and a chunk fell off revealing this. I thought maybe a gastropod cast that's settled in, but it looks attached? It's also not evenly spiraled. It doesn't show in the pictures, but the fatter section has an undulation to it. Worm cast? Anyone know what it is? (Sw Florida)
  21. Mind Blown

    Hello, I am reluctant to post this because of the flame I might get. I don't know how else to interpret this "rock". I can't believe it left as much detail as to even have the pink spot at the end of the trunk. Where should I go from here?
  22. What is this?

    I wasn't sure if this was a rock or a cast. I just found something in the first two photos. It looks like a mineralized blood vessel. Can anyone confirm that?
  23. Snail?

    I found this cast? Mold? Unsure of the correct terminology. I looked at the usgs website and they said snails were unlisted. I wondered if anyone had any helpful information they would share.
  24. Mussle Shell Steinkern

    This is a particularly fragile type of shell, made of many fine layers, and is prone to disintegrate as these did. This rare steinkern was found on a block of matrix submerged in the Chesapeake Bay. Dimensions are for the best-exposed steinkern on the block. The entire block is 14 cm wide x 10 cm high x 5 cm deep.
  25. Please clarify for local discussion. Referencing the attached sketch: First is a coin simulating a fossil. If split at the red line, there would be 2 pieces of external mold. Correct ? or incorrect ? Second is a lens shape, like a saucer or moult of a pygidium. If split at the red line, there would be 2 pieces of external mold. Correct ? or incorrect ? Third is an egg or complete bivalve. If split at the red line, there would be 2 pieces of external mold and 1 internal mold. Correct ? or incorrect ? All 3 assume that the specimens have dissolved an left a void which if filled would be the cast. Correct ? or incorrect ? The local argument is that the pygidium moult example is 1 external mold (top) and 1 internal mold (bottom) because it is the "internal" side of the animal. I don't think that is correct. Just a local discussion needing clarification, thanks. ref: http://www.ucmp.berkeley.edu/paleo/fossilsarchive/casmol.html
