Juvenile Tyrannosaurus rex tooth from Hell Creek?
TeethCollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
I saw a Juvenile Tyrannosaurus rex tooth (or Nanotyrannus) with really good price.. Seller told that this is from Hell Creek formation, Garfield County, Montana. I can't find any oddity or fabrication... but I want to hear everyone's opinion since the price is too good to be true.

Two Tyrannosaurid teeth that I ordered early this week has arrived. This is the first tooth that I want to show, which is a tooth of a juvenile Tyrannosaurus rex (or Nanotyrannus). Since I personally believe that the Nanotyrannus is an invalid genus, I think this is a juvenile Tyrannosaurus rex tooth. For those who do not agree, this is a Nanotyrannus tooth. This tooth is from Hell Creek formation of Garfield Co. Montana. This is an 1-3/8 inch, and has some chips and scratches at the labial side, but I think this is still a great tooth.

These are all found in what I believe is the scollard formation at roughly the same elevation. The black one is what appears the least "Rex-like" to me. @Troodon

Tyrannosaurs likely hunted in packs rather than heading out solo

A new "T-Rex" tooth just showed up on our favorite site. It is not a Tyrannosaurus rex tooth however but a more common and far cheaper Carch tooth. We know this because of its more blade-like morphology, its slender profile, its shape, its smaller denticles and the sand on the base I already notice multiple bids on it and I have no doubt the price would escalate as many hopeful collectors would try their hands on getting a cheap T-Rex tooth for themselves. For anyone looking to buy a true T. rex tooth, there are several factors to take note of: 1) Thickness - T. rex had crushing teeth, hence the teeth are thick. They are meant to crunch through bone 2) Locality - T. rex teeth in the market commonly comes from the Hell Creek Formation and Lance Formation. These two formations are found in Montana, Dakota and Wyoming. If a tooth originates from Africa or Morocco, it cannot be a T. rex tooth 3) Price - T. rex teeth command a premium price. Even a small tooth an inch long may cost 500 USD or more. A 2.5 inch tooth would easily be 2k USD. While exceptions do occur, if a deal seems too good to be true, then you should be extremely wary 4) Source - Make sure you get your T. rex tooth from a reputable source. By that, I don't mean a seller with a high feedback score or someone who prints you a "cert of authenticity". I mean a seller who has a history of collecting or selling Hell Creek/Lance Formation material. Better yet, get it from someone who digs there 5) Morphology - Educate yourself on the differences between T. rex, Carch, Spino, Daspletosaurus and other large theropod teeth. That way, you can immediately spot inconsistencies such as serrations or colors that does not match a T. rex tooth 6) Cross section - If all else fails, look at the cross section. If the tooth has red sandy matrix or sand, it is most likely not T. rex but is more likely from Morocco Here, I will show an example of a red T. rex tooth that superficially resembles the Carch tooth above. Take a look at the thickness and cross section though and you would quickly realize both teeth have very different morphologies Getting an authentic T. rex tooth isn't cheap, nor will it be easy. But it will be worth it in the end when you finally obtain one. Good luck in your hunt and always feel free to ask TFF if you are unsure of an upcoming purchase

I obtained a nice Tyrannosaurus Rex tooth from the Lance Creek Formation of Wyoming. It was a good opportunity to try my hand at restoration. The tooth was around 80% complete, with some of the root missing and a dent near the tip. I only wanted to restore the latter part. Pretty good job, I think.

From the album: Dinosaurs
Species: Tyrannosaurus rex Age: Cretaceous (Maastrichtian), c. 66 million years ago Location: Hell Creek Formation, Montana, United States Quite small tooth fragment of a juvenile specimen (classically referred to Nanotyrannus, now no longer recognized as a valid genus), but serrations are preserved. Identifiable down to the genus and species level since Hell Creek did not have any tyrannosaurids other than Tyrannosaurus rex. -
Hello! I'm a new member (but not one that's likely to become a stranger). I'm eager to get any information/predictions you can offer on this tooth from the Powder River formation in Montana. Some of the areas I've been digging into thus far are: · Ballpark age/maturity/size of animal · Area/position on the jaw · Likely causes of damage (e.g., wear from tooth-to-tooth contact, wear from general contact with other animals, trauma prior to death, damage post-death) · Any repair/restoration signs observed. One of the main challenges I'm having is that I can't tell how complete this crown is, for measurement purposes--i.e., the tooth is cut short at the tip and at the bottom--which I don't think is the actual "base", since the serrations are still running). Some pics and ballpark measurement attempts (inches) attached.

Hi there! I recently purchased this online, could you please help identify this? the seller was unsure if it was a juvenile trex or a nano. It was found in Hell creek dawson County east of Glendive Montana Thank you :)

I was out yesterday doing a final hunt before the snow sets in here in Montana on the Judith River formation and found this claw along with this vertebra, no other bones around so possibly from the same animal. I have found theropod claws that are much smaller and this one is huge when compared. I searched for the tip but sadly couldn't find it. I assume because of the size it would be a tyrannosauroid but not certain. Can it be determined to be a toe claw or hand claw? Is the vertebra identifiable? @patrickhudson

is this juvenile t rex skeleton real?
Josesaurus rex posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I have now corrected my previous post to avoid breaking the rules. I saw this recently and it actually seems too good to be true. I suspect that it may be false, as the stone that contains it does not look very natural in color, although the skeleton looks quite good. if you could comment on that it would be great.

First Tyrannosaurus Rex Tooth, Scollard Formation, Alberta
dingo2 posted a topic in General Fossil Discussion
I took a trip out to the scollard formation in Alberta the other day for the first time. I've been hunting in Alberta for years now, but only recently decided to try and branch out from our old hunting grounds. I was unaware that there were T-Rex fossils in our province, but I read through a few old posts on this forum about some massive teeth being pulled out of Alberta so I decided it was worth a shot. I told my dad about it and we decided to drive out on his birthday. I ended up finding a few broken T-Rex teeth, one would have been well over 3 inches. My dad easily had the find of the day with this intact tooth. Probably the best birthday present one could recieve. We will definitely be going back soon, but I want to educate myself on the scollard more before we go again. I was planning to be able to identify the whitemud, battle formation, and kneehills tuff, but failed in practice. If anybody here has explored the scollard in the past, I'd love to get some pointers on navigating, as you can only run up and down the hoodoos so many times before you're done for the day.

I hope I'm not breaking any TFF rules by discussing fossil sales outside the sales forum. Does anyone know what is happening with Stan the T. rex? It looks like he is being put up for auction. Why did they suddenly decide to sell him? https://www.christies.com/features/The-life-of-Stan-a-T-rex-excavated-in-1992-10872-7.aspx?sc_lang=en&PID=en_hp_carousel_1

T-rex premax tooth real?
Tacosaurus posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello i am considering purchasing this T-rex tooth. The seller claims that their are no repairs with nice enamel and good serrations. with the only damage on the tooth mentioned being on the inside edge. My questions are simple is this really a tyrannosaurus rex tooth and is there any sign or repaired damage or anything that would indicate the tooth is fake etc. Information about the tooth: Age: 65 Million Years / Carter County, Montana Hell Creek Formation / Size: 2 inches long Below are the images they have provided.

tyrannosaurus, hadrosaur and other Dino Teeth Repair and Restoration?
CEP posted a topic in Fossil ID
A couple of the bigger Tyrannosaurus teeth I found this summer in Montana Judith River formation. I found this 3" tyrannosaurus tooth in about 400 pieces and was able to piece about 80% of it together over about 3 weeks and 30 hours, the other one is almost as big but was only in about 30 pieces and is still a nice brown color. I am no professional and did not want to pay thousands to have someone do it for me. I would like to get it filled in and solid, is there some putty or epoxy used to fill it in and hold it all together? Also had some other smaller Hadrosaur teeth I believe and maybe a croc tooth but not certain. can anyone ID those?
-
I found what looks like a couple t-rex teeth, there are 4 good size pieces and about 20 smaller pieces. Looks like a complete 2.5" tooth once I piece it together, maybe longer and another partial tooth. Is it T-rex? also what is the best way to glue the pieces together? Is it worth paying someone that knows what they are doing? Also would it be worth digging into that area and see if there are more?
-
Found in over a dozen pieces. Had repaired after I glued it back together.

Tip was missing and was repaired. White marks are from plant roots pulling minerals off the surface.

Ok, I just came across articles about soft tissue remains, apparently including some form of degraded blood, in a mosasaur. That of course, brings up the T-Rex soft tissue found, to me. I seem to understand what I keep reading, but I can’t help it, again I find myself thinking...Really? C’mon, REALLY??? Am I just misinterpreting the whole thing, or is there actually real, true, gen-u-ine unfossilized/in mineralized, preserved soft tissues and blood remains in these 70ish million year old “fully” umineralized animals? ...............HOW?????????????? How, when the rest of the animal, soft AND hard tissue has dissolved away so long ago, can any soft tissue remain? How do only small areas of the tissue remain? If conditions are so, that areas of soft tissue/blood residue remain, how do just small patches remain, but the parts immediately surrounding the patches have long since dissolved away? Conditions inside an intact bone, or intact stomach cavity, should be stable, shouldnt they? Not different from one centimeter to the next, especially so different that one spot dissolved dozens of millions of years ago, and the spot touching that one is still just sitting there, relatively preserved?

Tyrannosaurus rex Metatarsal
heZZ posted a topic in Is It Real? How to Recognize Fossil Fabrications
I just came across this. According to seller it belongs to subadult T-Rex, found completely intact. I would like to know if it's real or fake. Thanks..thumb.jpg.131e39521926927e07421f62225bbdc6.jpg)

Picked this up off the auction sight. Hell creek tooth out of Powder river county Montana. Not expecting a perfect ID. It's small and I know that makes em hard to ID. This guy is just shy of an inch and heavy for his size. I have meg teeth of comparable size that weigh nothing compared to this specimen. It does have some remaining serrations but not much. Anyway, regardless of nano or rex status I thought it was an interesting tooth.
