T. rex or Nanotyrannus tooth?
Tressmeister posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I am trying to identify if this is a T. rex tooth. It's described as "natural juvenile Tyrannosaurus tooth". Location: Hell Creek Formation, Montana. Dimensions: Height: 4.3 cm Width: 3.8 cm I've read this awesome post by troodon, and I'm leaning towards T. rex ("fat" and rounded tip) - but looking forward to seeing your opinions as well. Thanks and have an awesome day ahead!

Surely someone in the group knows which T.rex cast is used at the entrance of the Denver Museum of Nature and Science. This display is known as the "Dancing Dinosaur" as well as the "Rockette Rex", after the Radio City Rockettes dancers. I thought it would be an easy answer to find with a search, but I none of the links mention which cast it is.

Warning, on our favourite auction site, a number of fossils from lower Permian of Richards Spur, Oklahoma are been sold as Hell Creek. The items are listed as coming from Hell Creek, Eastern Montana and are advertised as species of theropod including partial jaw/skull , jaw bone and nasal skull bone. This is the correct iD and is from original Vendor who first bought this to the market

Tyrannosaurus rex (Osborn, 1905) Late Cretaceous, c. 67 Ma Hell Creek Formation, Isabel, Dewey Co., South Dakota, USA. It has been a dream since childhood to own a Tyrannosaurus rex tooth and my dream came true with this recent acquisition of a gorgeous T. rex 1.5” dentary tooth.

MrsR and I had an audience with the king at Nottingham Natural History Museum, Wollaton Hall. An exhibition apparently showcasing the only real Tyrannosaurus rex to be displayed in England for over a century. I think is about 20% complete. Found by Craig Pfister near Ekalaka, Carter County, Montana. The mounted Titus skeleton measures 4 metres (13 ft) high and 11 metres (36 ft) long. The reconstructed the mount used a cast of the Tyrannosaurus specimen Stan to supplement the known bones of "Titus". Titus was found near to a triceratops that also will be joining him at Wollaton Hall in November. Wollaton Hall has a fantastic little collection of natural history that I show at the end of my post. Cheers Bobby

I have an interesting question when I read a paper (Hurum, Jørn H.; & Sabath, Karol. Giant theropod dinosaurs from Asia and North America: Skulls of Tarbosaurus bataar and Tyrannosaurus rex compared) I only found that it was mentioned in the content, T.rex had stereoscopic vision(Stereopsis), but I did not find any description of the vision of Tarbosaurus. Does anyone know that Tarbosaurus had stereovision? If Yes or No, please explain the reasons and provide a paper to prove it.Please Thanks guys. have a lovely day

Hello I am looking for help to identify these two teeth. I was told that they are T. rex but I feel either one of both are Albertosaurus but not 100% sure how to tell. I have included many photos and measurements. Both teeth are from the Hell Creek Formation. The first tooth and the shorter one is measures 2" long by 1" wide The second and longer tooth measures 2 1/4" long by .3/4" wide. Any information would be appreciated.

Saw this listing and was wondering if it’s more likely to be trex or Nanotyrannus. Length 1 3/4, width 37/100 and height is 6/10. It’s pretty long and the base is kinda circular on 2 sides. but it’s also not very robust, its slender and seems like there is a tiny pinch. I also think it may be a premax tooth? I’m leaning towards t.rex but interested in hearing other opinions

How can you tell a difference between a Juvenile T.rex tooth and a Nanotyrannus 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 would be easier to find. I think my favorite thing about this tooth is how worn it is, because that means it was used a lot in life. Thanks in advance for any help!

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
-
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.

STILL don't have our first T.Rex tooth yet
hadrosauridae posted a topic in General Fossil Discussion
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.

Hunting along the Scollard Formation in Alberta?
Dinoman28 posted a topic in General Fossil Discussion
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 be much appreciated. Cheers -
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 tooth out whole. Now I need to find my photo scale to count serrations. This tooth has a lot of wear but there should be enough left to make a good count. Within half an hour, 2 more Rex teeth were uncovered by other diggers. Another storm was building and there was worry we would have to jump and run again, so those with finds were trying to get them out quickly. I began packing up my gear but the storm blew past us to the south, so we went back to digging. That was when my son found a Pachycephalosaur hornlet! It was kind of funny because at first it looked like just another BOB, but as my son scraped away some more matrix from it he said "Its got a weird wrinkled texture." When I looked at it close I yelled " I know what that is!!" For those unfamiliar, Pachy material is VERY limited, so this piece is going to be made available for research and study. As rare as this little find was, it would be dwarfed by a find from another group that day. Someone found a Pachy skull dome at one of the new sites! I was hoping Walter would be so excited that he would prep it out that night, but he had other things that needed attention, so we only got to see the dome. Any attached hornlets were still in the matrix block. Hoping that he posts some prepped pics soon! So 2 more good finds from my son, but I struck out this day.

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
-
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

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!

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!

I’ve been noticing a lot of tyrannosaur teeth that seem almost intermediate between T.rex and Nannotyrannus. There are plenty of teeth that seem quite thin, and nanno like, but they lack the “pinching” at the base. I wasn’t sure if they should be considered rex or nanno. Maybe it has something to do with the base being incomplete, and maybe the pinching would be there had the majority of the base been in tact. If the base of the tooth where pinching normally would be on a nanno tooth is missing, is it possible for nanno teeth to have rex like base shapes?I was also wondering if it’s possible for nanno teeth to not have “pinching”. Is is posible for there to be some T. rex teeth that are just thin? I’ll post an example of a tooth base I saw that I thought had T. rex like shape, but nanno like thickness. It lacks pinching, but again I think the base is incomplete.

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 Gorgosaurus, and because of this was likely an ancestor. This sounded reasonable to me, but I understand you can’t trust everything you read online, and I wasn’t sure what the current scientific consensus was on the ancestor to T.rex. This is the link to the article https://magazine.scienceconnected.org/2017/03/dinosaur-gave-rise-tyrannosaurus-rex/
