  1. Hello All, I'm new to fossil collecting as well as this forum. I'm looking to pick up a T Rex tooth and came across the one in the attached images. I'm just wondering if you could help me verify that it is genuine? It comes from the Hell Creek formation so I believe it is, I just wanted to be sure. Also, if anyone has any reputable sources for T Rex teeth, that would be great to know as well (PM). Thanks in advance!! -Derek
  2. Step aside Sue, the T rex. The attached article finally describes the largest T rex discovered from the Frenchmans Formation of Saskatchewan, Canada after being discovered in 1991 Abstract Here we describe an extremely large and relatively complete (roughly 65%) skeleton of Tyrannosaurus rex (RSM P2523.8). Multiple measurements (including those of the skull, hip, and limbs) show that RSM P2523.8 was a robust individual with an estimated body mass exceeding all other known T. rex specimens and representatives of all other gigantic terrestrial theropods (Paywalled) https://onlinelibrary.wiley.com/doi/10.1002/ar.24118#.XJQsTuqqy7k.twitter An Older and Exceptionally Large Adult Specimen of Tyrannosaurus rex W.

  3. I have been working hard lately on all of our programs and we are very close to having the dinosaur presentation I want us to have. We have a name for this program, Dinos Rock. Yes it is not super creative but for 2nd graders, this is a geology themed program. For 3rd graders, it is adaptation based but the name works. We have added some pieces that gives us more than a few teeth. Nothing museum quality or anything but a few bones help the visual factor. I have been studying the biology, geology and ecology of dinosaurs so the science will be good. my son is working on the art but we wont have any done soon, he has school projects a head of this. We are close to being ready a full 6 months before I thought we would be. Hell Creek was going to be a focus for us because the fossils are available and this is the fauna that most kids will recognize. If you are willing to look hard, you can also find some real bargains from this formation. We turned a lot of early attention collecting attention to Hell Creek dinosaurs and I am actually really happy with where we are at with the fossil material we have. There is a lot of room to add and maybe upgrade in the future but this is a good start. This is the famous T-Rex and Triceratops fauna and we started our collection with those critters. Very early on, we were able to get a few Hell CreekTriceratops teeth. I am very happy that through a purchase from TFF member, we added two frill pieces. They are Lance formation but we are not covering the Lance formation yet so they will be used here. I also added a frill piece from Hell Creek. The kids will get to touch the largest frill piece which is a great bonus. An iconic dinosaur and I think well represented. Also early on, we stumbled into a great bit of a luck. A TFF member saw a post of ours and passed it on to another TFF member who sold us a beautiful Tyrannosaurus Rex partial tooth and gave us a really nice Nano too. It was very affordable and a generous gift was added that gave us nice pieces from the most famous dinosaur ever. The rock star really. I was not sure we would be able to get a decent example at all but to do it right off the bat was HUGE. This would not have happened if not for the members that decided to help us out. We are extremely grateful The first dinosaur fossil we got were two Hell Creek Edmontosaurus teeth that were a gift. We acquired a nice jaw fragment in a trade. I am a bargain shopper with a limited budget so I LOVE our Edmontosaurus as it has not cost much at all. I named this display Eddie I like it so much lol Hadrosaurs are important dinosaurs to talk about and I think a fair amount of kids may not know about them. I would like to add another bone later too. They seem attainable for us. Acheroraptor was behind only T-rex on the my list and we got a really beautiful tooth and it was another bargain pick up. I will talk a lot about this species and I will get deep into the biology/ecology of this awesome dino because I love Dromaeosaurids. Raptors are also an iconic dinosaur that kids love and this is a relatively new species which is another fun thing to discuss with the kids. We will also be introducing the kids to a theropod they have never heard of, Richardoestesia gilmorei. I have told me son to envision a toothed Cormorant type dinosaur as I lean toward them being a fish eater. It is pretty cool to get a Hell Creek dino that they will not know anything about. We have yet to add a Thescelosaurus fossil but we will before we start presenting. I want to add another piece of the fauna and it seems this is the most inexpensive option we will have. It will also give the kids another dinosaur they probably do not know and it will round out the basic Hell Creek fauna. There is no shortage of dinosaurs that we can add either. An Anky or Nodosaur scute is way up on the program list of fossils for me and hopefully we can find one from this formation. Dakotaraptor is #1 on my personal list and I will get one eventually. A Troodontid is also very high on the list as well. I know eventually i will also pick up an Ornithominid too. All three of these are more expensive so we will have to save and wait but each one would also make awesome educational dinosaurs. I also really want to add an Avian fossil. I have not researched this but my guess is they are very rare. Leptoceratops is another species I would love to add at some point too. They are really cute and kids will dig them. Anyway, here are some of the fossils. I think we have a good start going to our Hell Creek collection and I am looking forward to taking these to work with me very soon. Pic 1- Triceratops teeth and Eddie Pic 2- T-Rex, Nano, and Hell's Thief. I am so happy to have these fossils. Pic 3- One of the frill pieces. This one will end up in a larger Trike display with more teeth and another frill. Plus we will have nice frill for kids to check out too.
  4. Hey guys, Over 4 inches and was discovered in the famous Hell Creek formation

    These are T-rex tooth fragments. They have very nice large serrations.
  7. Do you think this item has any repairs and is it a genuine t-rex tooth? I t is 2 5/8 in lenght.
  8. Tyrannosaurus Rex tooth

    From the album My Collection

    Hell Creek Formation, Faith, South Dakota, USA It is a beautiful tooth with no restoration. The tooth has the characteristic d shape profile of a trex tooth on the basal side and this sort of preservation is actually fairly common with tooth also collected from other locations such as Wyoming. The first ever dinosaur tooth that I owned!
  9. Hey everyone, I was just wondering what the size range (preferably in inches) is for a Tyrannosaurus Rex Tooth is. Thanks! - FossilsandScience
  10. Is this really T-Rex Premax tooth? Size is slightly less than 2 inches (T-Rex Premax tooth rarely exceed 2.5 inches). Can it be some other Dinosaur teeth such as Nanotyrannus? Thank you.
  11. I bought this specimen on eBay about 10 years ago, from a reputable seller who had a lot of other Hell Creek material. It was listed as a Tyrannosaurus rex tooth, from the Hell Creek Formation of Montana. It obviously has a lot of repairs and is quite fragmentary, but overall seemed to be a genuine fossil, and for the $350 I paid it seemed like a good deal. But recently, on closer examination, I got a little worried. There is no trace of serrations whatsoever on any part of the tooth, which seems odd- the only non-serrated large theropod teeth I know of are the spinosaurids, which this doesn't resemble overall (and which don't occur in the Hell Creek anyway). I guess what I'm asking the dino tooth experts here is a) Should I be worried about the lack of serrations? and b ) Is there anything else suspicious about this tooth? I tried to get different angles for the photos, but am happy to take more if that might be useful. Any help is appreciated.
  12. Newest Rex Tooth

    Good morning all, it has been a bit since I've posted here. I recently picked up a nice Tyrannosaurus rex tooth from the Hell Creek formation. This tooth has a lot of character to it. Even though it is not huge by any means, it has beautiful enamel and excellent serrations. I just wanted to get everyone's thoughts on it. Thank you!
  13. Tyrannosaurus Rex Tooth? ID

    Hi everyone, I am new to fossils and have got hold of a Tyrannosaurus Rex from someone I know. The tooth was found in Hell Creek Formation, Faith, South Dakota USA and is 2.5 inches in length and the teeth itself is really heavy (pics attached). Let me know if you need me to take clearer photos of serrations as it is quite hard as my camera's macro focus doesn't work very well. As you can see from the pics this teeth has some surface wear to the enamel and serrations... Serrations worn may have been from feed wear. Please can you help me identify if its from the Tyrannosaurus Rex as opposed to one of the members like the Nanotyrannosaurus or Carcharodontosaurus? Thank you! Jai
  14. Check out my new t rex partial limb bone. Any expert thoughts, comments?
  15. My most recent and most exciting acquisition, a giant partial vert from a tyrannosaurus rex from the hell creek formation of Montana. Nearly went into cardiac arrest that I was able obtain such a large specimen from t rex, so I thought I would share. It really fills up the dinosaur collection and feels like it weighs a ton, I think the dimensions are somewhere around 6.5 inchs or so long and 10.5 inchs tall if I remember, would've been alot taller if the process was still intact and I like how the giant pores are visible cause of the damage. Super massive piece, I was worried about it collapsing my shelve but it fits fine so far.

  17. Good afternoon all, I wanted to get some opinions on determining if a tooth I am thinking about purchasing is either a T-Rex, or a Nanotyrannus tooth. I will post some pictures of the tooth, and supply what information I know about it. • The tooth is 1" long, with a round cross section. • Robust serrations. • Found in the Hell Creek Formation, Powder River County, Montana. Due to the round cross section and serrations, I have been leaning towards classifying it as a T-Rex tooth. I'm very interested to hear member thoughts.
  18. New research says T. Rex couldn't run

  19. Indianapolis Children's Museum

    Hello, I was stopping through Indianapolis and gave their children's museum a try. It was surprisingly enjoyable! The museum covered topics from agriculture to racing to dinosaurs! These photos are from the dinosaur section. I followed the signs to the Dinosphere. I walked through the entrance and down the ramp. At the end of the ramp was a Sarcosuchus cast (no picture sorry). Following the path I emerged into a huge planetarium like structure filled with dinosaurs.
  20. Hi Everyone, I'm trying to determine if this tooth does indeed come from a Tyrannosaurus Rex. It's a small tooth which makes a positive ID a little tough, but I'm leaning towards this being a Rex tooth. Can anyone confirm as to whether this is a genuine Rex tooth, or something else such as a Nanotyrannus tooth, or Tyrannosaurid indet? When I asked for photos of the base of the tooth the seller mentioned that he had read @Troodon's post about T-Rex VS Nano teeth too . The base does seem more rounded versus rectangular. Information: Size: 1.1 inches long Formation: Hell Creek Location: Garfield County, Montana (Private Land)
  21. Tyrannosaurus Rex Tooth ?

    Hello, i have this 2 inch long " Tyrannosaur Rex " Tooth , but i am not 100% it is a Rex. The seller sent me this Information: Species: Tyrannosaurus Rex Formation: Hell Creek formation of Wibaux County Location: Montana, USA I hope you can confirm it is one. Kind Regards , Michael
