  1. How can you tell a difference between a Juvenile T.rex tooth and a Nanotyrannus tooth?

    T.rex dentary tooth?

    Hello! I recently got this tooth as a birthday present. It's a roughly .5" tyrannosaur tooth from the Hell Creek formation. I'm pretty confident this is a Tyrannosaurus tooth based on the very circular thick base, but I wanted to check in case it could possibly something else. Also, when I first looked at it I thought it was an anterior dentary tooth, but now I'm starting to think it may be a lateral dentary tooth. I was hoping someone could tell me roughly which position it would be in? I can provide any additional pictures. The tooth is very worn, and I circled both sets serrations so they w

    ID Please!

    Is this A Tyrannosaurus Rex or a Nanotyrannus tooth? Here's what I know: 0.75" (1.9 cm) Hell Creek Formation of Bowman County Nouth Dakota. @Troodon
  4. Why is Tyrannosaurus the only dinosaur that is mainly referred to by the genus name and the species name? I mean, nobody talks about T. horridus or D. longus but nobody also just talks about plain Tyrannosaurus.
  5. I thought this year that my son had found our first T.Rex tooth. Its both larger and thicker than any of the Nanno teeth we have dug. I was 99% sure we had our rex until I just used my (crappy) phone camera to finally get a serration count. 2.8/mm. Thats clearly in the Nanno count. Maybe next year will be our year.
  6. Hi all, I'm heading out into the badlands in September and I thought I might try my luck along the Scollard Formation. I've found some good resources online but it seems Scollard is much less described than the nearby Dinosaur Park and Horseshoe Canyon formations. I'm wondering if anyone can point me in the direction of further resources or offer some personal experience with hunting along the Scollard formation. At the moment my strategy is to start in Dry Island Buffalo Jump and work my way north, but I'm not sure I can sufficiently distinguish Scollard from nearby layers. Any thoughts would
  7. For day 3, it was decided to go back to the Deers Ears butte. Everyone was sore and worn out from 2 days of hiking, so a chance to stay in a single spot and dig would be a chance to rest. My team went to the Tooth Draw quarry, the others went to other sites, including one new one. The day started pretty slow, but then mid afternoon my son uncovered a tooth (havent determined T.Rex or Nano). I was so proud of him, he did an expert job in recovery. The tip was broken insitu and could have been easily separated or lost, but he was slow, careful and judicious with the paleobond and got the to

    T.rex skull?

    Greetings, I have now received some pieces of bone, it should be pieces of bone from the Tyrannosaurus' head ... it should be one individual ... if anyone can confirm or refute it, or even know which part of the skull it is. ..I would be very grateful ... for some pieces, I already have an idea where they fit ... I photographed every piece of bone 5 times ... you can see a part of the surface of the bones at each one .. I just don't know if I'm wrong, so I'd rather ask here, the more erudite ones ... thank you for your time

    T.rex Tooth?Please ID

    Please identify this tooth, unfortunately I do not have more photos available, nor the location of the find, or any information, but I think that identification is possible anyway ... maybe the color, the guidance of the curve will reveal something ... thank you for your time.Luk
  10. A very popular site has some "Tyrannosaurus rex" teeth. Here are two pics of one. Description does say Morocco yet also says T. rex. I see a repaired carcharodontosaurus tooth ( a dino not mentioned in the posting). Anybody have a different opinion? This person also has incredibly small hands for a 5.85 inch tooth!

    Stan- The T. rex

    Stan, the T.rex is offered by Christies tomorrow in New York What an extraordinary piece of fossil! Here's a link to the fossil and its history: Take a look! https://www.christies.com/features/The-life-of-STAN-a-T-rex-excavated-in-1992-10872-7.aspx?sc_lang=en#FID-10872
  12. I bought this tooth last week, and it arrived today. I’m really excited about it, because it’s my biggest tyrannosaur tooth so far, and I believe it’s T.rex. It was found in the Hell Creek formation, but no other locality is given. I think it’s T-rex because of the base lacking any pinching, and the overall robustness, but I always like to hear any opinions others have. Thanks!

    T. rex ancestor?

    I read an article a while back that compared what the writer considered to be the most likely ancestors to T.rex. According to the article, Daspletosaurus is the most likely ancestor to T.rex. The article had some pretty interesting points about anagenisis, and how D. torosus probably evolved into D. horneri, and that the entire lineage ended with T.rex. One of the more interesting things I read was that a lacrimal bone was found in the Judith River Formation, and it was thought to be from T.rex. The article said that Daspletosaurus had eye sockets more similar to T.rex than Albertosaurus or
  14. Hi all a little bit of fun , I would like to show your all my Hell Creek collection. I photographed and arranged them in a Top Trumps Style graphics. Thank for looking and I hope you enjoy my post. Bobby

    I found this website that has some fantastic photos of dinosaur bones. Definitely worth a look. Great for reference. http://www.theropodaexpeditions.com/ Some examples
  16. it's labeled as nanotyrannus/"raptor" tooth and it's from hell creek, here some pics:
  17. So I have been looking at some T.Rex and Nano rex teeth for sale and I came to the conclusion that they are extremely over priced some 1 inch rex teeth sell for over 400$. Why are they so expensive?

    Another T.Rex tooth

    New addition to my tooth collection, this guy is 2.65'' tall and 1'' wide (0.75'' thick). Pretty nice color & enamel on both side and overall great serrations on both sides. The size and lack of any heavy feeding wear suggest to me that this tooth could have come from a younger individual. Locality: Hell Creek Fm., Powder River Co., Montana. If you have been looking for one of these you might recognize it from a recent update on a popular online fossil store. Yes it isn't the cheapest route of getting a dinosaur materials but I think its better safe than sorry, espe

    Tyrannosaurus teeth

    hello everyone, i'm looking for a good looking (and reseonably priced) T.rex tooth. can you tell me what these teeth cost, becaue i see some online for 500 $ to 3000 $.
  21. Hi folks! I'm a little late to the party here, but this was posted on a popular fossils website. I apologize for the delay in posting, but I couldn't take a photo without having the website's name exposed. This specimen was listed as a very elusive T.rex hand claw, at a reasonable price. Unfortunately, it is an Anzu wyliei foot claw and not a T.rex hand claw. Misidentifying these two claws is a very common mistake. The second photo is the Anzu wyliei toe claw from my collection. If any of you purchased this claw, please contact the seller. Information came to me last night by member

    ID needed for my new tooth

    Hello dear fellow fossil lovers Recently my interest of collecting stuff has shifted to dinosaur teeth, and having a decent sized T Rex tooth in my collection is a must thanks to my OCD. Dinosaurs has fascinated me ever since I was a kid. So after I sold one of my beloved guitars, here it is. I counted the serrations on both side, about 18-22 per cm so should confirm it is pulled out from an adult T.Rex based on what I have read. The info says it was unearthed from Lance Creek fm. Being a complete noob on dino fossile Please let me know what you guys think,
