T-Rex Egg? Maybe? or Maybe not?
Scuby109 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Is this a T Rex Egg Fossil? or just a really large 6 or so inch rock that looks like one? The guy selling this told me that before he removes anything from where he finds these, he gets local Paleontologists to check them out. Thoughts?.thumb.jpg.74dddd5d1965c96f1e08bc9a370d0487.jpg)

Identification This is a classic T. rex tooth. It's clearly Tyrannosaurid by its robusticity, similar serration densities on each carina (mesial carina counted by the "roots" of the denticles as they are completely worn off), and chisel-shaped serrations. Those qualities with its locality and formation mean it must be the one and only. Notes The Crown Height Ratio (CHR) suggests a posterior position (it's short and stout). There's evidence of wear on the tip and mesial carina.

Identification Tyrannosaur teeth characteristically have similar serration densities on each carina, with chisel-shaped denticles. Though small, this tooth matches those qualities, and doesn't resemble other smaller theropods like Dromaeosaurids. Identified as Cf. T. rex based on its similarity to another, larger tooth in my collection. Notes This tooth is from a juvenile individual. Serration densities illustrated in the above photos. There is a slight pathology (bend) near the tip.

Identification Tyrannosaur teeth have similarly-sized serrations on each edge, and the serrations are chisel-shaped. This is a classic "Nano-morph" tooth being compressed and blade-like (which is the primitive condition of Tyrannosaurs). Notes This tooth has excellent preservation, with serrations crossing the tip, and clear enamel. There is a minor wear facet near the tip on the lingual side, indicating this is from the left maxilla.

Tyrannosauridae (Nanotyrannus-morph) Hell Creek Fm., Powder River Co., MT, USA A classic Nanotyrannus Tyrannosaur tooth: compressed and blade-like. Exceptional preservation, with a minor wear facet near the tip on the lingual side (indicating it's from the left maxilla). I really like the color.-

Hey everyone, didnt know there was a thread for drawings lol how cool. Ive always enjoyed drawing, but found that they always come out better when done out of procrastination lol. Anywho, this rex was done today and thought Id share it. It was inspired by the JP rex, although the scales were just too time consuming to draw as I had to go back to studying, so just replaced some of the scales with shading haha. Thanks for looking!

Tyrannosaurus rex Hell Creek Fm., Wibaux Co., MT, USA This is a juvenile Tyrannosaurid tooth. The serration densities are similar on each carina, the serrations are chisel-shaped and robust, the tooth is not recurved, and the mesial carina is straight. It closely resembles my larger T. rex maxillary tooth in cross section. -

Hi y'all, got this small theropod in the mail; I bought it suspecting it was Tyrannosaurid. Upon in-hand inspection, I believe that suspicion is confirmed. It bears close resemblance to one of my larger juvenile T. rex maxillary teeth. It also appears to have a slight pathology near the apex - a slight bend. @Troodon Tyrannosauridae Hell Creek Fm., Wibaux Co., MT, USA CH: 9 mm Mesial serration density: ~ 5.3 / mm Distal serration density: ~ 5 / mm Serration densities: Serrations: Here the pathology is more evident: Base (comparison with other T. rex maxillary tooth, right):

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.

Are there any excursions other than Paleoprospectors where you pay for the fossil excursion and you can keep your finds? Hells Creek

?Tyrannosaurus rex Lance Fm., Weston Co., WY, USA 1" X 1.5" X .5" I got this bone perhaps foolishly last year (although it wasn't very expensive at all; that coupled with the provenance that follows is why I got it). It was sold as a T. rex bone chunk, like many you can find online. There is nothing identifiable about these hunks of bone - you need something more substantial like a whole bone to be certain. I got this bone from a seller who finds many of the fossils himself, was director of a small museum in South Dakota (now gone I believe), and found T. rex "Ivan." This bone was in association with a (pes) claw, toes, metatarsals, tibia, ischium, gastraila, and other limb bone chunks in one site that he identified as all belonging to T. rex. The credibility of the seller and the association I think makes a good case for this being from T. rex. If you really want to spend your money on something like this, you need association (ideally with photos available), and an authoritative source doesn't hurt. -
Houston Museum of Natural Science + T. rex Victoria - July 2021
ThePhysicist posted a topic in A Trip to the Museum
I was in the area, so I made a very brief stop by the HMNS. I'll state up-front that this will be extremely dino-centric. What I saw was really great, they have a chronologically-organized display of animals from stromatolites to humans (I only made it to the Cretaceous). The lighting is very dramatic, so seeing it in person is much better than the dark photos portray (I did edit a few of them to enhance visibility). Lots of dynamic posing which is nice compared to other museums. Also, most specimens aren't behind glass, and you can get really close. I believe most of the skeletons are casts (except for a couple of exceptional ones), but they're done well and don't disappoint. They currently have Victoria the T. rex as a traveling exhibit, although I think it has been recently moved and reduced in size to make room for the new traveling exhibit. She's one of the most complete individuals of T. rex and only slightly smaller than Sue (12' tall, 40' long, ~10.5 tons). Victoria was found in SD in 2013. She died sometime in her 20's (?), possibly from an infected bite on her lower jaw from another T. rex. Various elements: I think the feet aren't original. Coracoids, furcula, gastralia: Caudal vertebrae: Cervical vertebrae, some are fused: They had one of her femurs and her skull displayed separately:

Hello everyone, The Land Before Time and jurassic park are some of my favourite movies but i really not know nothig about fossils;) Recently i found in the Alps Mountains here in italy what to my eyes is only a strange rock, i'm here to ask you if the thing you can see in the attached video can be some kind of fossil. Many thanks to everyone 1728365416_WhatsAppVideo2021-06-07at19_09_56.mp4
