  1. I found this tooth while in Montana! I have no clue what it is. I was told that you guys could help! If you guys need any more information, tell me Found Near Fox Crossing Montana, Judith River Formation. Hill County
  2. Rhaeboceras halli

    A new edition to my collection. I was told that the original finder of this item listed it in his journal a Rhaeboceras Sp. and the seller said her source could not find it listed. A check of the internet proved it be an ammonite. Location matches his journal entry. SPECIES Rhaeboceras halli AGE Late Cretaceous - Upper Campanian Stage View on Geological Time Scale LOCATION Rosebud County, South Montana FORMATION Bearpaw Shale SIZE 2 1/4 " wide 5.8cm x 1 1/4 inch thick. CATEGORY Ammonite Fossils
  3. Pachy dome spike?

    Going through some chunkosaurus boxes tonight and found this piece that looked fairly pachy right off the bat. Maybe it’s a stretch because I’m still a little depressed that I traded away the pachy dome we found earlier in the year, but this piece sure looks like a worn spike to me. Am I right or am I wrong? Only the one angle shows the “spike” but I wanted to show all angles. The backside looks very pachy as well. thanks guys judith river formation of Montana - milk river
  4. Dino claw?

    I was going through my box of chunkosaurus bones tonight to see if I missed anything from any of our first ever fossil hunts. Found a bunch of cool verts, pachy chunks, amongst other things. But this one’s got me thinking - especially after my buddy @CEP found A huge tyrannosaur claw last week. I’ve been crying myself to sleep every night that I didn’t find it. anyway - could this be a super worn tyrannosaur claw? JRF milk river Montana. The only asymmetrical part is the top where it’s the most worn. Worn tip - well - work everything. Do me a favor @Troodon or @jpc and give me some good news or, I’ll just continue to cry myself to sleep if it’s an indeterminate dinosaur bone -and sorry the pics are rotated - they were vertical when I uploaded
  5. Theropod jaw piece?

    Sorry about my not sweet picture skills. found Judith river formation of Montana - milk river. obviously a chunk of jaw, but we usually just find little croc jaws. This one is bigger, and the sockets just seemed theropod to me right off the bat. Grabbed a couple tyrannosaur teeth from my daughters display in her room and they fit like a glove. Super scientific, I know - but thoughts? thansk!
  6. This topic is for information purposes of an experience I just encountered when looking at a Tyrannosaurid tooth on an auction site. You often see me request additional locality information when trying to ID a dinosaur tooth. I'm always concerned that the sellers provenance is not specific enough when it comes to material from Montana or Alberta to verify that the Formation provided is correct since it affects identification. Here is a good example of one case that paid off. In this case what was being offered for sale was several listings of Albertosaurus teeth from the Judith River Fm of Montana. I really liked the quality and color of the teeth so I followed up on one of them. I already knew the ID was wrong since no Albertosaurs have yet to be described from Montana so I needed to verify locality/formation.. Also the color was not typical of teeth from the JRF, a red flag. So I asked the seller about a locality beyond Montana and he immediately replied that the JRF was North Central Montana. I replied that I knew where the JRF was located but needed to understand where the tooth was found Town or County. He had to contact the digger and within a reasonable amount of time got back with me that it was Pondera County. Thats Two Medicine Fm different group of Dinosaurs. BTW seller was very helpful with no intention to deceive. Bottom line is that you need to do the best you can to verify what is being offered since you did not collect it yourself. Don't assume the ID or Formation provided is correct...Verify, verify as best as possible. Always request a town/county to be included in a provenance. If you can post interest here on the forum. Here is the tooth.
  7. Hello! This tooth has been offered to me. The id is theropod ind. It has very small serrations... From Cloverly Formation. What do you think? Thank you so much!
  8. Can you see anything wrong with it?
  9. Tyrannosaur tooth ID

    I bought this tyrannosaur tooth a while back and it says it’s a albertosaurus, gorgosaurus, or daspletosaurus. Is there anyway to narrow it down any further? It says it was found in the Judith river formation of eastern Montana and it measures just over an inch. Any and all help is appreciated.
  10. Some type of claw

    Judith river formation / Montana finds. I thought they were Dino claws, but they’re not fossilized feeling/looking. They don’t seem curved enough to be hawk, so I’m stumped. I know a lot of things it’s not, just not what it is thanks for the help
  11. Theropod bone?

    End of a long bone found in the Judith river of Montana. seems a bit bigger than the normal little chicken/goat sized ornithomimid stuff we usually find - but it’s hollow (and pretty) and can anyone explain the odd markings on the articulating surface? Where tensions would run? thanks for the help (and I love this forum by the way)
  12. Weird Dino bone

    this is a weird one. It seemed like a tiny piece of inner jaw, but it isn’t parallel like I remember those being. It flares out like a shell, but it’s bone. And it has what looks like a digit indentation in the one end. Thoughts? Thanks so much Judith river formation - Montana

  16. The virus put a damper on my Spring dinosaur collecting trip but I was able to get a partial one in for the Fall. I was able to spend several days at my usual Edmontosaurs bonebed but unfortunately only one day at a channel deposit in Montana where theropod/mammal material can be found. Hopefully next year will be more normal, Hopefully. Quite a few new members since my last trip so I will get into more specifics to get them a view of how I collect this material. First let me share with you a view of the collecting area and the LOCAL wildlife that we deal with on a daily basis. The area in Montana is very remote no phone or internet The badlands where we collect in South Dakota The most beautiful critter that we see everywhere on these sites and all over the west is the Pronghorn. At this time of the year we typically see a small herd with a bull and his harem. For those of you not familiar with a Pronghorn its the fastest animal in the western hemisphere able to achieve speeds in excess of 50 mph (80 km/h) Mule deer are ever present and very dangerous if you are driving when dark The site is located on edge of cliff and over the years lots of holes and cavities have been created by erosion creating a wonderful winter den area for the local snakes. So during our fall trip its not uncommon to have visitors slither by us and of course wishing us good luck by waving their tongue Here are some we have seen this season: The only dangerous one is the Prairie Rattler but they typically are not interested in bothering us. You just have to watch where you are walking. Being from Arizona its normal... The Western Ribbon Snake The Yellow belly Racer The Prairie Bullsnake We do have more cuties' Tiger Salamander after a rainfall On to collecting Other than a pick and shovel these are the tools I use 90% of the time to collect I use two glues, Paleobond field prep and stabilizer. The latter on teeth and when I need a very strong deep bond. Harder to prep with PB002 so its only used when needed. For wrapping the bones Heavy duty aluminum foil does the trick where minimal support is needed . Where additional support is needed on large bones we use burlap and plaster. However plaster cloth like the one in the photo works most of the time and is a heck easier to use than burlap
  17. I know it’s Dino - that’s all

    Judith river Dino bone - I’ve got lots of guesses. The bone looks croc ish, the end looks hadrosaur ish, but I’m totally stumped. It’s like an elongated ceratopsian toe claw that got twisted on the bottom Its most definitely not an egg though. Could be a chunkosaur
  18. I found a bunch of these teeth on the Judith River Formation yesterday and not sure of the identification. Based on google searches they appear to be (from left to right) triceratops, ankylosaurus, and Hadrosaur. The one on the left is about 3/4" as a reference. Any direction would be greatly appreciated.
  19. Dino claw

    Judith river Montana Dino claw. Figured it was a type of raptor claw, but wanted to see if anyone could shed more light on this one. I’m pretty sure it’s not an egg thanks
  20. I hate to do it, but.... egg?

    I’m sure it’s not, but I’m not sure enough not to ask. I read the “is this an egg” post and am still not sure. There’s just a few pieces of the superficial layer left. It’s textured and has a thin outer layer: so, is it an egg? found Judith river formation along the milk river in Montana. thanks for the help
  21. Possible claw?

    Wondering if this is a rock or some type of fossil claw. Found outside Terry, Montana in the badlands.
  22. Gorgosaurus libratus

    I have here a Tyrannosaurid tooth identified as Gorgosaurus libratus. It's 3/4" and the provenance is Montana. I'm wondering if the Gorgosaurus claim appears to be accurate. Thank you, Bellamy
  23. Richardoestesia or Dakotaraptor?

    Hi everyone, I just got this tooth from the Hell Creek Formation of Carter County, Montana. It was labeled as Richardoestesia, so based on the curvature, I was assuming the proper ID would be cf Richardoestesia gilmorei. However, when taking some measurements, what caught my eye was that the mesial carina appeared to end 1/3 from the base, and I started to wonder if instead this tooth could possibly be Dakotaraptor. These are the measurements I was able to get: Mesial: around 5.5-6 serrations/mm Distal: around 5 serrations/mm CH: around 16.5 mm CBL: around 7 mm CH/CBL: around 2.4 The crown appears to be smooth, the base is almond shape, and I believe the denticles have rounded tips. Please let me know what you all think. Also, some of the measurements may need double checking. Thanks!
