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. -
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. -
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?- 4 replies

Hello, I was doing a study on the T. rex and Nanotyrannus teeth specimens I had, and I wanted to compare them against a list of known T. rex teeth with measurement. The paper: Dental Morphology and Variation in Theropod Dinosaurs: Implications for the Taxonomic Identification of Isolated Teeth (JOSHUA B. SMITH, DAVID R. VANN, AND PETER DODSON) contains a list of 115 T. rex teeth. To make it easier to compare and read the data, I combined the measurements into a single chart, added colors and lines for ease of reading, and added the size and names of the T. rex used in the study Feel free to refer to the below chart for T. rex teeth measurements. I had to split the chart into 2 due to size limitations, but if you want the full-sized PDF version (25 MB), please message me so I can send it to you by email. If you have any suggestions to improve readability, or have your own data to add, go ahead and post it here! I will be posting pics and measurements of my various T. rex and Nanotyrannus teeth here @Troodon- 3 replies

We all know that spinosaurus is most possible to be the largest theropod. Spinosaurus was not very tall (in the hip) but it probably was heavier and longest that tyrannosaurus, giga and carcha. But, what is the second biggest theropod ever? (only carnivorous, not herbivorous like deinocheirus). I think, that tyrannosaurus rex is the second biggest theropod ever. Giganotosaurus and carcharodontosaurus was longest that t. rex, but not tallest and heavier. Giraffe is taller that elephant, but elephant is the biggest terrestrial mammal. Argentinosaurus, supersaurus, patagotitan, diplodocus, was longest that blue whale, but blue whale is the biggest animal ever.

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?

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?

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.

I recently came across the young earth theory (the theory that earth is 10.000 years old and dinosaurs coexisted with humans and traveled with Noah and his ark) and of course i thought it was unfeasible but one common argument they keep having is why are we finding soft tissues, proteins and other biochemicals in fossils like triceratops, t-rex and other dinosaur bones of course that doesn't mean DNA BUT they shouldn't have been preserved because such biochemicals don't get preserved after so much time. Another one is that some old fossils are still close to the surface when they should be buried really deep. So what are your thoughts on these arguments, in my opinion this theory is ridiculous but i'd love to learn the answers. Thanks (PS sorry for asking that many questions these days its just that im new to the forum and have lots of questions)

After the Velociraptor skull, I finally finished another very long project: the baby T. rex skull designed by Inhuman Species, a 3D printed museum quality fossil replica of a 2-3 years old Tyrannosaurus rex. I really love this project and I made a video of the making from the 3D printing to the painting - I hope you like it. If you're wondering, I 3D printed the skull with the Alfawise U30 in PLA plastic; please watch the video and turn on subtitles to learn more about the tools and the making processes. If your're addicted or interested in 3D printing, you can't miss those topics:

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

Cool article from Business Insider on the most accurate T.rex so far to date. This new exhibit is featured at the American Museum of Natural History, NYC also featuring the Tyrannosaur lineage. Really dig the new look! https://www.google.com/amp/s/amp.businessinsider.com/what-paleontologists-got-wrong-about-tyrannosaurus-rex-2019-3

Can a partial tooth or tooth shard be correctly Id'd as a T-Rex?
fossilsonwheels posted a topic in Fossil ID
My son and I recently started an education non-profit using fossils. Since the little kids love dinosaurs, we decided to include them in our programs. I do not know much about Dinosaur fossils but I am trying learning on the fly. There is no way we can pick up a full tooth or large bone from a T-Rex. our purchasing power is limited. I did find a dealer that has several partial teeth or tooth shards listed as T-Rex. They are affordable for us and did come from Hell Creek. I am apprehensive about buying any of them though because I do not want to drop any money on something called a T-Rex unless I can be fairly certain that is what it is. I do not possess enough knowledge to ID a partial tooth nor do I know if you even can correctly identify a tooth shard. I will put to this those here with far more knowledge than I have.... Can you ID a tooth shard as T-Rex and if that is possible, what would you look for ? Thank you in advance for any help that I can get
