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

Only other info I know is it's supposedly from Liberty County, Judith River Formation. About 2" long. Doesn't look like a carch tooth so I'm hoping it's actually T-rex.
-
Hi everyone! So, yeah. I keep going back and forth on this one. I've been told it's Nano, but the serration count seems low for Nano (23 per cm distal 25 per cm mesial) and it looks a lot thinner than it actually is on account of a piece of the base missing. That and it's really big for a Nano tooth. Dimensions in mm are 50 x 18 x 11 Dimensions in inches are 1.97 x .71 x .43 The pictures are labeled rex because that's what I though it was originally. This is just bugging me so I'd like a second (or more opinion) just to put my mind at ease once and for all.

Hello everyone! I just started learning about dinosaurs and am very excited! I’m trying to grapple with some weird things about the T-rex and was wondering this: could T-rex have been a “persistence” or endurance hunter? I’ve been reading things that say the T-rex was probably slower than most of its prey. Rather than out-sprinting its prey, might T-rex have simply been in “better shape”? That is, might it have been capable of sustaining an elevated pace far longer than its prey, then relying on superior tracking skills to relentlessly close on hiding prey attempting to cool down and recover from exhausting sprints? I’ve heard this method proposed for early hominids and wondered if T-rex might also fit the bill, but I really don’t know what goes into a successful “persistence predator”. Thank you all for being understanding - obviously I’m new at this - and thank you especially for not laughing at yet another monumentally uninformed crackpot idea! https://en.wikipedia.org/wiki/Persistence_hunting

I have just become aware of this barbaric practice! These beautiful creatures are being forced to "race" for the amusement of the onlookers! I would not be surprised, if illicit wagering were part of this opprobrious "entertainment." Contact you congressman now! This shameful, cruel practice must be stopped! Look at the poor condition of the exploited animals at the end of the video. Some of the lovely creatures appear to have broken their necks in their effort to please heartless humans! This senseless depravity must stop!

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

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. -
Should I restore this, or Keep as is? T-Rex gastralia.
PrehistoricWonders posted a topic in Fossil Preparation
Hi everyone, do you all think this would look better with the cracks filled and fully restored or as is? -
Hello. A while ago I purchased this specimen from a highly reputable and established seller. It's a T-Rex jaw fragment from Lance Creek, Wyoming, and was a surface find (see photos of the original specimen in situ; according to the finder, "the piece in question is at the very bottom left, on top of the edge of the longer bigger bone; the tooth grooves are face-down."). I'm reaching out to Fossil Forum for guidance along the following lines: 1) What part of the jaw is this most likely from? I've been studying images on-line at a cursory level, but I can't find the distinction convex part of the bone that my specimen has (the part that sticks out like a thin ridge). Any thoughts or, even better, photos of comparable specimens? 2) I trust the original seller, but since it was not found as part of a larger Rex specimen, I figured I'd ask for your confirmation: is this almost certainly a T-Rex? I'm fairly knowledgeable regarding teeth, but not mandibles. Thank you all very much in advance; any insight would be deeply appreciated. With best regards and gratitude, Ryan

Hi all, I could not resist and purchased this tooth knowing it would be a tough call to make. It was found in the Hell Creek Fm. The big problem is the worn down mesial carina, there are however some remnant denticles I could measure, but not midline – more posterior. Taking them into consideration the tooth has distal 4.5 denticles per mm and mesial 6 per mm. The other measurements are: CH 1.47 cm / CBL 0.74 cm / CBW 0.39 cm. Based on this and the oval base I am leaning towards Dakotaraptor but might as well be a specific T-Rex tooth position.? I really need someone more experienced to take a look please. Any help is highly appreciated.

I found a mark of suspected skin in the deepest part of the large footprint of a suspected dinosaur? I found very little data on the toe skin marks on the Internet. Some people know what the skin texture is on the toes of large theropod dinosaurs?

Hello All, So recently I've been doing a little bit of reading on random fossil news to pass the time, and I keep reading a lot of comments about "illegal fossils" and whatnot. One specific specimen that comes up a loooot in my readings is the T-Rex fossils. Some mention the legality of the issue, some mention the fact that they might be going to private collectors rather than museums, and many mention both. I understand why the scientific community might want to perform research on the specimen, but seeing as there are more than a single T-Rex fossil that belong to museums, shouldn't this be fine to sell a couple to collectors? Also when a fossil is considered "illegal" what exactly does it mean? Illegal as in illegal to find, illegal to keep if found, illegal to ship overseas, and/or illegal to sell? Thanks, -Em

As the lockdown continues and I can’t go on any new adventures here’s another amazing experience from my palaeontological back catalogue. A little shorter this time than my Burgess Shale story. I was back home from university for the Christmas holiday and decided to go with my family to the Burke Museum in Seattle. I’d been many times before as a child but this time I was going to see something special the Tufts-Love rex, and I got lucky. We had arrived in the morning just before they opened and were one of the only families there, as I was peering into the lab area trying to see as much as possible, the preparator stopped, came to the door and asked if I wanted to see it up close. Next thing I knew I was face to face with the T-rex. Looking at it up close you could see the fine detail in the bone where veins ran into the maxilla and the almost feathered texture of the supraorbital ridge. She even let me touch it, something I never expected a museum to allow me to do. Of course I couldn’t pass up the photo op. In the picture the googly eye is in the wrong place, it should be up a little higher where in its place one of the preparators put a sticky not saying “no more prepping in eye hole”. Clearly the temptation to continue in further and hollow out the skull while it was still half in block was just too strong. You can also see one of the nasal bones has been exposed and has been displaced. At the time I got to see it, they weren’t sure if this meant that the other was missing or how complete the other side of the skull was. Now that the skull has been fully prepared we know (There is a fantastic thread elsewhere on the forum by @Troodon documenting its preparation). 100% of the skeletal elements are present and it’s one of the most complete skulls ever found. I haven’t seen it fully prepared yet though, since I haven’t gotten back to the Burke since it has been renovated but next time I’m back in Seattle it’s the first thing I’m going to do. Thank you all for reading, Benton

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?

Hi it is my Birthday today, and since it is my birthday I was going to get some fossils. I found this and am wondering if it’s a genuine tooth and if it’s a T-rex or not, if that’s possible through the sellers photos.

The discovery of the Tyrannosaurus rex led by a team from the Burke Museum made news last year. I've attached some photos of the preparation of the skull provide by the Burke Museum to show their progress with this dinosaur They have named this animal "Tufts-Love Rex" after Jason Love and Luke Tufts, the two volunteers who discovered it. Lower Jaw is exposed from its tomb. What a beautiful set of chompers The Skull is next. Maxilla More will follow as work continues..... @Pagurus

Hi the debate about Nanotyrannus got me thinking is Nanotyrannus found in Alberta Canada in the Scollard or Frenchmen Formations. If not then it could be valid since T-Rex is found there and if it’s a juvenile Rex then there should be a least some evidence for It there, since T-rex’s are found there. And if so this could provide Nanotyrannus’s range.
