Hi all, Thanks so much for the kind feedback on my Berthasaura reconstruction. Here is another example of my work: A 'juvenile' tyrannosaur skull based loosely on Jane (BMRP 2002.4.1) I'm aware of the debates regarding age and species however I have just approached this as younger individual. Thanks so much for checking out my sculpt. I'm printing a prototype as we speak, I'll post some updates on here once its assembled!

Hey I was hoping someone could help me to figure out type of dinosaur this tooth was pulled from?, Giant fossilized dinosaur tooth it weighs 2 lb 4 oz and is 7.25 cm in diameter at the cusp, the shape of the cusp is similar to that of a spade from a deck of cards. the middle section is 8.25 cm diameteral, and is 9.5 inches in length. Geology where the tooth was located was in the eastern part of the state Kansas in the United States

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!

Hello everyone, I'm new here, and I need some help. I have this T-Rex tooth in my collection, and thought it looked like a Carcharodontosaurus tooth. Are these Carcharadontosaurus teeth, or are they T-rex teeth, perhaps found somewhere in Texas?I saw a T-rex. tooth that was in Texas, and those teeth looked pretty similar. Unfortunately, I don't have any information on where they were found, so I wanted to ask if anyone has any ideas on how they identified them, or if anyone knowis if T-rex was also found in Texas. Thanks! Hallo zusammen, ich bin neu hier und eure brauchen Hilfe. Ich habe diese T-Rex-Zähne in meiner Sammlung und dachte, dass sie wie eine Carcharodontosaurus-Zähne aussieht. Sind das Zähne von Carcharodontosaurus oder sind es die Zähne von T-Rex, die vielleicht irgendwo in Texas gefunden wurden? Ich habe einen T-Rex-Zahn gesehen, der in Texas war und diese Zähne sahen ziemlich ähnlich. Leider habe ich keine Informationen darüber, wo sie gefunden wurden, also wollte ich fragen, ob jemand eine Idee hat, wie man sie identifiziert hat, oder ob jemand weiß, ob T-Rex auch in Texas gefunden wurde. Danke!

Hi, thoughts on this? The base looks Rexy, but the tooth is quite thin rather than fat, so I am thinking it might be Nano, not Rex? Any thoughts would be great. 1.2 inches, from Powder Rivery County, Hell Creek

Hi all the experts, I am new to this area and would like to acquire my first Nano OR T-rex tooth. Since most of them cost ~ $$$$. I need some help to decide what should I do. I encountered three on the websites. All claimed un-repaired. Are they good samples? Which one do you think is better to acquire?

Hello Everyone, I bought this tooth nearly ten years ago as a Albertosaurus tooth from the Two Medicine formation, Montana, U.S.A. Whilst updating my labels I have learnt that Albertosaurus is not found in the Two Medicine Formation. As a result, i am asking if anyone can ID this tooth (i know it is very difficult or more likely impossible). I believe it is either a Distal Maxillary or a Distal Dentary tooth. The MC is 18 whilst the DC is 16 which gives it a DSDI of 1.125. The tooth is 2.90cm tall and the base of it is 1.22cm by 0.86cm. the link to some fairly high quality photos is: Tooth Id - Imgur thanks in advance, Josh

Imagine strolling down the street with your very own pet dinosaur. Who would dare mess with someone sporting a prehistoric buddy? With a T-Rex or a triceratops as your loyal companion, bullying would be a thing of the past. After all, who needs to worry about bullies when you've got a dino-sized bodyguard that can turn them into scaredy-cats with a single growl? Just make sure your neighbors don't complain about the occasional tree-trampling incident. While having a pet dinosaur might solve your bully problems, it might create a few traffic jams in the process!

Hey everybody. Last year I bought one of those T-Rex air scribes from the UK that runs on 50 psi. It appears to be equivalent to the Paleo Tools ME 9100. I also have a Paleo Tools Super Jack but that runs on 90 psi. I run it at 110 psi. Here is my question, Is there a big air scribe out there in the market that is equivalent to the Super Jack but runs on 50 psi? Thank you RB

Hello everyone ! I bought this Tyrannosaur tooth and the seller told me it was either a Tyrannosaurus rex or a Nanotyrannus. Can you tell me if it's a T-rex or a Nanotyrannus ? It's a premaxillary tooth. It comes from Hell Creek formation in South Dakota.

Hello everyone, A Tyrannosaur tooth here, it measures 1.1 inches, and is from Wyoming (Weston County) Lance Formation. If anyone can ID it as Nano or T-Rex, that would be much appreciated. There some very slight serrations, which I have zoomed in on. Thanks for the help.

this is shocking... Christie’s Pulls T. Rex From Auction, Citing Need for ‘Further Study’ - The New York Times (nytimes.com) but, for my opinion its the right decision and Black Hills is absolutely right. I am a bit frustrated that the selled did not give the right infos about the T-Rex, no teeth are original, that it is a "cast" of Stan and no one really knows how many bones are original.... When a fossil like this will be offered for sale honesty is absolutely necessary! Hope the seller will be banned from Auction-Houses

Hi everyone! I recently acquired a very large (3.5+ inches) digested Rex from McCone County, Montana. The seller said no repair or restoration and I just wanted to make sure. I shined a UV light on it and there is one area that I'm interested in. Along the mesial Carinae is a very dull green under the UV. I tried to capture it with my phone but all I got was blue light since my Camera isn't equipped for that. Typically when I see restoration it's a very bright and vibrant green under UV so I'm not sure if this dull green area is restoration, if it's just an area that was stabilized, or if that's just there sometimes. Here are the pics I took, although my question is primarily "what does very dull green under UV light mean?" Any insight is appreciated!

I have this very tiny tyrannosaurid tooth from hell creek formation, south dakota. Im wondering if it's possible to know if the tooth is from a infant nano or t-rex? Distal serration density: about 6/mm Can't see any intact serrations on the mesial side. Crown Height: 4 mm Crown base-lenght: 2,5 mm Crown base-width: under 1 millimeter, about 0,8 mm to roughly estimate (very hard to measure this one).

Tyrannosaur Rex Premax Tooth condition
Jacobloven posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! I’ve been thinking of purchasing this T-Rex tooth. As you know they do not come cheap nowadays so I would really appreciate any input. According to the seller it was found in Hell Creek formation, South Dakota and has no cosmetic restoration whatsoever. It’s in it’s found “crushed state”. Approx 3 inches long and 1 3/8 inches wide. Do you see any red flags with it? Thanks!

Here's a (hopefully) interesting question on a topic well outside my wheelhouse. In the break room at the Florida Museum of Natural History sitting on top of the double refrigerators is a cast of a coelacanth, a painted resin cast of a Tyrannosaurus rex foot (the left one), and inexplicably a cleaning sponge that one of the artists at the museum has modeled into a cartoon character named Robert with quadrilateral trousers. I've been looking at these objects while nuking my lunch in the microwave oven next to the refrigerators for several months now. Just yesterday I finally noticed that there was something odd (to me) about the T-rex toes. Leading up to the ultimate distal/ungual on each of the three toes (disregarding the hallux "dew claw") are a varying number of phalanges. Somehow I had naively assumed that the number of phalanges in each toe would for some reason be consistent. For reference, each of the digits in our human hands have two phalanges (proximal and intermediate) leading up to the distal phalanx (ungual) on all but our highly useful opposable thumbs. Our thumb (pollux in medical speak) makes up for the missing intermediate phalanx by having a metacarpal that has more mobility than the metacarpals of our other digits. I found it fascinating to learn that the 3 primary toes of a theropod dinosaur, labeled II, III, & IV, have (very conveniently) 2, 3 & 4 phalanges leading up to the distal phalanx. I came across this excellent artwork from a paleoartist online: https://emilywilloughby.com/art/gallery/diagrams/theropod-foot-comparison It seems that our modern day dinosaurs (birds) share this same asymmetry in toe bones as the T-rex that started this little investigation. I'm guessing that to those who have taken anatomy or physiology classes or have a deeper understanding of birds or dinosaurs this would be common knowledge but somehow I've never paid enough attention to theropod feet till now. I do so enjoy learning new tidbits of information (quite regularly from this forum). In the off chance that this might be enlightening to other members I thought I'd share my micro-epiphany instigated by some T-rex toes on top of a fridge. Cheers. -Ken

From the album: Hell Creek / Lance Formations
A young T. rex tooth. The preservation of the enamel is fantastic, and I like the dark hues. The serrations are also in great shape. There is some minor feeding wear on the tip. -
From the album: Hell Creek / Lance Formations
For most collectors, it's more affordable to have a piece of a T. rex tooth if you just want it represented. This one is clearly T. rex: it's theropod with serrations (this one has the basalmost portion of the mesial carina), very thick, and clearly would've had a large circumference. Note also the large angle made by the curvature of the tooth at the carina (not Nanotyrannus which have narrow, blade-like teeth). -

Hello! I inherited this piece with the idea that it could possibly be a space rock. I checked the magnetism and it has no magnetic properties whatsoever. After closer examination with an open mind and a little imagination, I see a petrified baby dinosaur laid on its side with its neck possibly broken at the base of the skull. Below what looks like the neck is a split section that looks like a chest cavity with a arm/leg on either side. . The strangest part is that there seems to be the head of another species resting on the side of the laid down fossil. I see the right eye socket at the top of the head and the raised ridges on top of the skull back to the decapitation point. (It almost looks like it could be a tiny horse laid on its side, but it looks like little fingers on the end of what looks like the front leg)

Hi all. I'd like to begin by thanking the members of this forum for the profound wealth of knowledge that you all have shared with me during my search for further understanding of dinosaurs, fossil collecting, and fossils in general. Prior to joining, I was a longtime lurker that regularly referenced this forum and its many posts to answer countless questions that I had, and I continue to reference it! The information contained on this site is invaluable. I would especially like to thank @Troodon for his amazing guides and detailed write-ups, such as the case made for Nanotyrannus. That really settled the debate for me and convinced me that Nanotyrannus is indeed a separate genus. So thank you all! Now, with that out of the way, I'll get to the point of this post. I recently got my feet wet in this hobby and did what I'm sure MANY beginners have done before me. I began by acquiring a fossil of the most well-known dinosaur, and my personal favorite, Tyrannosaurus Rex. Specifically what was advertised as a partial T-Rex tooth. I can't afford a complete tooth at the moment, so I settled for the next best thing. Based on everything I've learned so far regarding T-Rex teeth and how to ID them, its characteristics seem to lean towards being a Rex tooth, but I'm by no means an expert on the subject, so I'd like to call on the many members of this forum that have more experience than I do and ask if they would be so kind as to share their opinions based on the photos and information provided. So as for the tooth's information. It's a partial tooth that measures 1.38 inches long, and the seller stated that it was discovered in the Hell Creek Formation of Powder River County, Montana. It does seem quite robust, and its shape and relative size seem consistent with Rex teeth. It also has a pretty round cross section. The serrations also seem to be pretty in line with Rex teeth, but I don't know if they provide any clear differential to typical Nano serrations. Photos taken by both the seller and myself have been attached. Thanks in advance for any help/opinions provided!

Hello, Any thoughts on this? Adding a Rex bone would be awesome, if I can get it confirmed as been legit. Hell Creek, South Dakota, said to be possible end of a scapula 7 x 4 3/4 x 1 Now, weirdly, when I try to contact the seller I get an error message. So I can't get a more exact county/town yet---but hopefully that error will be fixed so I can soon. So, is the ID on this good? Also, the bit near the top where the ID number is added--the color looks off. Is that restoration? Thanks for the help
