  1. HC Theropod tooth

    Listed on everybody's favorite auction site as a Dromaeosaur or Tyrannosaur tooth. 1/2" long theropod tooth. Hell Creek Frm, I believe it said South Dakota but I will double check that. It was very inexpensive so I went ahead and bought it. If nothing else, seems an excellent candidate for some analysis and it was a good way to test what I have learned without breaking the bank lol So lets see if I have gotten better at this. I believe it is Dromaeosaurid based on the difference in serration size and density. The seller posted good pictures so I could count the denticles. No exact scale in mm but the count was done mid tooth. Distal= 12 Mesial=14/15 The mesial serrations look pretty straight. The denticle shape does not look like the Acheroraptor teeth I have and the density difference is less too.I am not seeing ridges. It does seem to be compressed as a Dromaeosaur would be. I know there will be some work to do when it is in hand with measurements and checking out the base. My smartest option is to tag @Troodon and get his opinion lol For now I will go with Dromaeosaurid indet. I think it could be a DR candidate. Either way, it is a nice tooth with nice serrations and a bargain to boot
  2. Here is a really interesting bone. Despite being pretty small and a partial bone, this would be an excellent addition because you can get a great look inside of it. This is the type of bone that lends itself to some serious teaching I think. It is from Garfield County in Montana, Hell Creek Formation. 1 7/8" x 5/8" x 5/8". It is small and partial but it appears to be in excellent condition. It is listed as a raptor bone and my limited knowledge says that is a possibility. It sure looks like a theropod of some sort (bird, troodontid maybe I do not know). I would love to hear any and all thoughts on this one !!
  3. Hi all, I have a tricky tooth ID question. For now it is labeled as Theropod indet. and I guess this is as far as it gets, but I just want to check if someone else gets a Dromaeosaurid vibe =) It was found in the Lourinhã Formation. Crown height is 6mm. Denticles per 1mm are 9 mesial and 7 distal. Mesial denticles are also much shorter, and the mesial carina ends at about half way from the anterior of the tooth (maybe 2/3 considering the tip is missing). Distal denticles are slightly hooked towards the anterior. I went through quite some papers from similar aged formations in Portugal/Spain and Morrison formation but without any real luck: Zinke 1998 describes possible Dromaeosaurid teeth that might fit the bill regarding denticle density and roughly TCH/FABL/BW when scaled to this tooth (6.09mm/3.61mm/1.95mm). Any help is highly appreciated!
  4. I recently added a Dromaeosaurid vertebra to our collection. I honestly did not bother with specs once I got it confirmed as Dromaeosaurid. I never asked size or what formation. I assumed it was from Judith River because it was sold as Dromaeosaurus. i knew it was going to be Dromaeosaurid indet so I was not worried about the specific ID. It is a raptor fossil so I wanted it. The vertebra arrived today and I got two very pleasant surprises. It is bigger than I thought. It is also not from Judith River or the species known from that formation. We got a Dromaeosaurid vertebra from the Hell Creek formation Many of our fossils end up being listed as a indet species. This one went into our official inventory as Dromaeosaurid indet. An indet species gives us some degree of latitude with our programs. I assign species to many of them such as Medusaceratops or Zuul from Judith River so that we can teach the kids dinosaurs they do not know about. When I first saw Hell Creek on the paperwork, I thought "Great, we have a vert to add to our Acheroraptor display which contains a single tooth." I began to think that I should assume it is from Acheroraptor because I had run across a published paper about a reconstruction of Dakotaraptor's tail. I thought it might be a good idea to reread that paper and see what information it provided. Our caudal vert is 5 cm long. Much to my surprise, that is right in the middle of the size range for a Dakotaraptor caudal vertebra according to the reconstruction (if I read the paper right). Now I am not saying this is a Dakotaraptor vertebra. I am nowhere near qualified to make that call. I also doubt I am lucky enough to find a fossil of that species by total accident lol I am also not qualified to say for sure that this is not a Dakotaraptor fossil. As an educator, this gives me a really awesome option. I am now considering that this may be an opportunity to add Dakotaraptor to our program with a fossil that MAY be from the giant raptor. Kids would dig that and it gives us the chance to talk about how the science, and art, of describing dinosaurs works. I think I am going to to print up the paper and give kids the information from it. They can see the fossil and come to their own conclusions. We do this with the lineage of Great White sharks. We show the kids teeth from a GW, a Meg, and a Hastalis. They can make their own conclusions though 80% of the kids the other day believed hastalis is the ancestor of the GW. It was a fun thing to do and it would work very well this fossil too. Dakotaraptor has been high on my list to add but I thought it would be down the road. I do not think there is any problem with introducing this fossil as possibly being from Dakotaraptor. Either way, we added an really cool fossil that I am super stoked about. Here is our Hell Creek Dromaeosaurid indet vert. Is it Acheroraptor or Dakotaraptor ? I am going to let the kids decide which awesome raptor this fossil is from.
  5. Today is my last day off before I go back to work and I was supposed to spend the day making fossil starter kits. I have a cold though and I do not want the kids to think that 12 million year old shark teeth gave them a cold lol I am pretty bored so I thought I would post about our Judith River dinosaur fossils and how we are going to get discuss this formation. I am really surprised how much I am enjoying learning about these dinosaurs and this will be a formation that we spend a good bit of time on. It must have had some very productive ecosystems and there is a great diversity here to discuss. The kids will also get to see some familiar dinosaur families while learning about species that are new to them. I think during adaptation related presentations, this formation lets us get into ecological niches and discuss how two Tyrannosaurids existed as did at least two species of Dromaeosaurids and a Troodonitd plus other predators including non dinos. That is a lot of hungry mouths so niche selection and adaptations become very important. THere is also a great diversity of herbivores in this formation. I love the Ceratopsians from this formation and the diversity gives my son a lot of artistic options. We currently have one tooth but by the time we present we will have a couple more I think. This allows us to present a few species and say the teeth are not diagnostic so the teeth could have belonged to one or more really cool looking horned dinosaurs. This also gives the kids knowledge that there other Ceratopsians besides Triceratops. This will also be the point where we introduce Dromaeosaurids. Raptors are just iconic and this formation gives us the chance to really hit on adaptations. We have a Saurornitholestes tooth and will soon have a Dormaeosaurid caudal vertebra. While not assigned specifically to Dromaeosaurus, the vert will presented that way so we can talk about the differences between the two raptors. Of particular interest is the larger skull, more robust teeth, and specific wear patterns on the teeth of Dromaeosaurus. We will also have a small tooth tip from a Tyrannosaur indet. The kids will love learning about other Tyrannosaurids and I will leave it to the kids to imagine which one it belonged to. The real owner of the tooth is not important. That two existed in this formation is what is important. They must have occupied different niches plus a lot of kids may think T-Rex was the only member of that family. The last fossil I know we will have from Judith River is one of my favorites. It is an Ankylosaurus tooth and thanks to some help from TFF members, I spotted this among a few Nodosaur teeth. In our inventory, this is Ankylosaurus indet. However, in every single dinosaur presentation we do this will be Zuul and it will be a rock star. We want the kids to understand that there are many new discoveries being made and there will be a lot of new dinosaur discoveries made by THEIR generation. Everything about Zuul will be cool to kids. It is the one of the most incredible fossils ever found, armored dinosaurs are just cool, and it even has a pop culture name that a lot of kids will recognize from Ghostbusters lol Only 5 fossils but we can do A LOT of quality education with these fossils. I also have a very clear idea of the next items to find from Judith River. #1 on that list is a Dromaeosaurus tooth. A tooth gives us the perfect way of illustrating the difference between the raptors. We have two more purchases to complete before I buy again so I will save up and in the spring I start searching for that tooth. I also would love to add a hadrosaur bone from this formation and eventually I will track down a frill piece. Anyway, here a couple of the fossils... Pic 1- our Saurornitholestes tooth. Not a great picture but a really nice tooth. Pic 2- the Dormaeosaurid indet vert. Not here yet but will be right around my B-day. Pic 3- the Anky tooth. It is just a cool tooth and Zuul is a great dinosaur to teach kids about so Zuul is what this tooth is for Fossils on Wheels. Our only fossil from an armored dinosaur.
  6. Judith River Dino Id Help

    All of these items are from the same dealer and I am looking for some ID help. I researched these as much as I could on my own but I can only get some far with the knowledge I have. All of these come from the Judith River formation. For our education programs to really be solid, we need to expand beyond just teeth. We do have an Edmontosaurus jaw fragment and will soon have some Ceratopsian frill pieces plus some bones fragments from the Morrison Formation. I think it would be a good idea to augment the small dromaeosaurid teeth we have a bone or two so I am trying to understand this part of dinosaur collecting better before I make a purchase. I do not want to repeat the error I made with the Troodon vert (which did have a happy ending as the dealer graciously agreed to exchange that for a frill piece). Any help on this is greatly appreciated. The first one is listed as a the pedal phalanx from a Dromaeosaurus. I looked over as many photos as I could find of dromaeosaurid phalanx bones. It does look similar to several photos I found. I have a few questions on this one. Is this the phalanx of a dromaeosaurid dinosaur ? Second question is more of a general question. Can you even determine a genus or species based on an isolated phalanx? The second one is listed as a distal caudal vertebra of a Dromaeosaurus. This one was far more difficult to find anything to reference on the internet. I found nothing that could give me an insight as to whether or not this is a dromaeosaurid vertebra. Is this is from a dromaeosaurid dinosaur or any kind of theropod for that matter ? I have a pretty good idea now of what to ask dealers when it comes to theropod teeth but isolated bones are pretty new to me. Are there questions that I can ask of the dealer to further the ID process? Thank you in advance for any assistance you can provide
  7. I was hoping somebody on TFF might be able to point me in the direction of any scientific papers, research or information that members here might have put together regarding dromaeosaurid theropods from the Judith River formation. This is not really about identifying any teeth, though I do have one from that formation. I am starting to do my research for the education program and am looking for scientific information. From what I can gather, there is a possible Saurornitholestes species and of course the dinosaur I have seen referred to as Julieraptor, which is a interesting story all on its own. I have also seen Dromaeosaurus listed from that formation. I would like to sort out what is known and unknown from the formation and the best way to present our "raptor" tooth to the kids. Any help links or suggestions as to where I might find more information on this would be much appreciated
  8. Theropod Claw Confirmation

    And now my last fossil for the night, one of my favorite fossils in my collection ever is the theropod claw my dad found (I always give credit when he's the discoverer) in the Lance fm. of Wyoming the summer before last. It was identified by the guide as potentially being a Nanotyrannus hand claw but I wanted to confirm that with other members on TFF. It's about 2.5 cm in length.
  9. Me and my 7 year old boy went looking for fossils many times. We found a claw tip and a claw mid section from two separate expeditions in two different areas within the river valley a kilometer apart. I believe we have a sickle claw tip from one hand of a dromaeosaur and a sickle claw mid section from the opposite hand. I would appreciate any additional id that could be made from these photos.
  10. Fast. Intelligent. Deadly. The "Raptor" is perhaps one of the most famous dinosaur today thanks to Jurassic Park. To many people's surprise however, raptors are heavily feathered and nimbler than movies would have you believe. The Jurassic Park Velociraptor was merely the size of coyote in real life! In fact, their proper family name is 'Dromaeosaurid'. The largest species was Utahraptor, and it grew to the size of a grizzly bear! Dromaeosaurid fossils have been found all over the world. They first appeared during the Cretaceous, though isolated teeth have been found in the mid-Jurassic. Allow me to present my humble collection of Dromaeosaurid teeth. First up, from Cloverly Formation, one of my pride and joy from @hxmendoza A dromaeosaurid from Aguja Formation. I am seeing more Aguja fossils showing up, but dromaeosaurid teeth are still rare. Now, for the dromaeosaurids from the famous Hell Creek Formation. Some of them probably lived alongside T. rex. A big shout-out for @Troodon for getting me started on dromaeosaurids with this very first Acheroraptor!
  11. Always like to see discoveries of dinosaur material from the east coast especially from North Carolina. Here, the first definitive occurrence of a dromaeosaurid from the Tar Heel Formation is reported on the basis of a tooth from a fairly large member of that group. The tooth described in the paper is intermediate in size between those of smaller dromaeosaurids like Saurornitholestes and gigantic forms like Dakotaraptor. https://www.paleowire.com/just-out-a-giant-dromaeosaurid-from-north-carolina-cretaceous-research/ Paywalled paper https://www.sciencedirect.com/science/article/pii/S0195667118301253
  12. I noticed a Dakotaraptor tooth for sale and caution anyone interested in it to do a bit more homework before you buy. Dakotaraptor teeth are difficult to diagnose and can easily be confused with Nanotyrannus teeth. These teeth have been very difficult to find and are prized but be patient and be sure its the real deal. If interested my suggestion is to obtain more information on the tooth: A photo of the mesial carina. On the holotype the mesial carina typically ends 1/3 from the base A closeup pictures of the mesial and distal denticles, see below on what they should look like. Not box shape like Nano. From the photos provided it might look right but need that closeup A serration count midline of both edges 5mm wide. Being a Dromaeosaurid the serrations are larger on the distal carina than mesial one. . Denticle shape from DePalma paper included in my topic shown below
  13. Kem Kem tooth ID

    OK, I know it's gonna be an Abelisaurid, gotta check with you guys though! Pictures should say it all.
  14. Raptor Arm

    Partial right humerus (upper arm) of an undiscribed Dromaeosaurid. The size is very similar to that of Bambiraptor. This animal was possibly just over a meter long.
  15. It's been awhile since I posted so I thought I would share a few recent buys. These two claws are definitely some of my grail fossils. Enjoy!! Allosaurus hand claw, digit 2:
  16. Dromaeosaur Metatarsal

    Partial metatarsal of a Theropod dinosaur. Probably from a Dromaeosaurid. Very similar to metatarsal II and IV of Velociraptor.
  17. Raptor tooth

    Tooth of a velociraptorine raptor. Specifically the serrations of the tooth are typical of Saurornitholestes.
  18. Velociraptor claw Replica

    From the album Reptile Fossils

    Velociraptor mongoliensis A replica of the killing claw and toe digits of a Velociraptor. Original from: Djadokhta Formation, Mongolia Age: Late Cretaceous
