  1. Are these tyrannosaurus teeth?

    I didn't know which place to post this, but I found this online and I was wondering if these are in fact genuine T-Rex tooth? Thank you very much.
  2. Nice, cool big bone for sale from Hell Creek Formation Montana listed as rex, is it?
  3. Tyrannosaurus fibula?

    So, can anyone shatter my dreams with THIS one? Lol no, I'm really extremely appreciative of the help Ive been getting with questionable fossils, and the chance to learn important and helpful information! the description says it all...this is supposed to be a tyrannosaurus fibula fragment. Seems legit to me, but I could definitely use other opinions. This is a hell creeker.
  4. Hello what makes a good tyrannosaurus rex tooth its it the size and quality of it ?
  5. Tarbosaurus Tooth?

    Saw this tooth online recently, it already sold but it was listed as a Tarbosaurus Tooth but it reminds me more of a carcharodontosaurus tooth but then again I am unsure nor familiar with tarbosaurus teeth, what do you guys think? I have included all photos in the listing.
  6. T. Rex integument?

    I am in the process of creating scientifically accurate extinct plush animals, and I had a question in regards to the integument of Tyrannosaurus Rex. I know there is evidence supporting the scaly covering of T. Rex from various impressions from the Wyrex specimen, but I am unsure of the location, size and implication of these impressions. We want to make our animals (while made more 'cute') to be accurate to the scientific finds at the time of their production. However, I must admit a large attraction of the T. Rex plush is that it will have a feathery covering on it's body. Even though the feathers are highly speculative I think the idea of feathers on a T. Rex will get some people to question what they know and hopefully delve more into the science behind these creatures rather than just take recreations at face value. So my question in short is this: Where do we KNOW T. Rex had scales, how large were these scales, and whats the maximum size and location of coverage we could accurately speculate T. Rex could have had feathers without ignoring the facts? Thanks a ton for your answers and views
  7. What is the deal with the feathering on Tyrannosaurus rex? I can't really find anything reliable online, except for Mark Witton's blogpost about the topic, but some renowned paleoartists like Fabrizio de Rossi's recent "All Hail the Queen" artwork. So was T. rex fully scaly, did it have a few bristles on the back of the neck and on the trailing edge of the arms? I think that adults had some bristles while juveniles had much more feathering. What is the current theory?
  8. My T-Rex and Nanotyrannus teeth

    These are my T-Rex and Nanotyrannus teeth. I acquired most of them pretty recently. They are some of my most prized dinosaur fossils. I'll post my T-Rex/Nano bones soon as well. Pic 1 and 2= Nanotyrannus lancensis tooth, Hell Creek formation, South Dakota Pic 3,4,5= Nanotyrannus lancensis tooth, Hell Creek formation, Montana Pic 6,7,8= Tyrannosaurus rex tooth, Hell Creek formation, Montana Pic 9= Tyrannosaurus rex pieces and tips, Hell Creek formation, Montana Pic 10 and 11= Tyrannosaurus rex tooth, Hell Creek formation, Montana Pic 12= Nanatyrannus lancensis teeth, Hell Creek formation, Montana Pic 13= T-Rex and Nano fragments, Lance formation, Wyoming
  9. Straight Outta Mesozoic

    As a graphic design artist I sometimes like to create some paleo-art and pop-art mash-ups. Please feel free to comment.
  10. Hello TFF, I was scanning through a really popular shopping website and for auction, 3 t rex teeth were for sale. They are not in the most perfect or beautiful condition but hopefully and at the moment, they are around my budget. I just wanted to make sure that they are actual t rex teeth not nanotyrannus as it can be sometimes confusing. Would really like to ask for your opinions. The photos may be a bit blurry and unfortunately, these are the only ones available. BTW, The largest tooth was found in two and had to be glued together. The rest were found as one piece. Thanks guys!
  11. My most recent and most exciting acquisition, a giant partial vert from a tyrannosaurus rex from the hell creek formation of Montana. Nearly went into cardiac arrest that I was able obtain such a large specimen from t rex, so I thought I would share. It really fills up the dinosaur collection and feels like it weighs a ton, I think the dimensions are somewhere around 6.5 inchs or so long and 10.5 inchs tall if I remember, would've been alot taller if the process was still intact and I like how the giant pores are visible cause of the damage. Super massive piece, I was worried about it collapsing my shelve but it fits fine so far.
  12. T-rex illustration

    Hey everyone! Here's my latest piece of paleoart, T-rex! I used ink and watercolors. I didn't want to color it the traditional green or brown so I looked at vultures for reference. I find it difficult to believe the theory that T-rex was exclusively a scavenger but I thought the vulture colors would make it look nasty. Hope you like it and I'd love to know what you all think! -Mike
  13. Hi, I purchased a gift for my wife for our wedding anniversary. Both me and my wife grew up loving Jurassic Park and being fascinated by dinosaurs and I have recently started to get into fossil collecting! We are going to Weymouth in the UK next year as well so hopefully will spend some time on The Jurassic Coast fossil hunting! The picture is a Fragment of a Juvenile Rib Bone. I purchased it offline from a seller who has good reviews etc apparently the specimen is from Mongolia. I have looked into T-rex fossils and the price of a genuine tooth which is crazy money so I decided to purchase this bone fragment. I noticed there's a resin substance on the Fossil like a varnish and it feels very light but just wondering if that is just to protect it. thanks a lot W
  14. what do think about this ? An EXTRA LARGE, Good Quality Tyrannosaurus rex tooth. This crown measures 2-5/8" and is thick (1-1/16"). The enamel has excellent color and patina. Excellent anterior and posterior serrations. Some root etchinng on crown. Tip is blunt - very typical with adult Rex teeth. Several cracks were stabilized. Is this a fault/ disadvantage ??

  17. My Prehistoric Profile of the T.rex

    This is a Profile on the T.rex that I had written for English and would like to see what you all think and correct me on what is wrong about it! Tyrannosaurus Rex is one of the most famous of all non-avian dinosaurs to ever roam the earth, and is known by the name T-Rex. Well that is an incorrect wording as the correct way to write the animals name is T.rex. Very few people know this and is one of my life dreams to educate people about this. Tyrannosaurus means Tyrant Lizard king. The now outdated view of T.rex being a lizard with poor eye sight and lumbering, is incorrect. In all actuality Tyrannosaurus rex was a warm blooded feather coated bird that could run to 25 miles an hour and actually had the best eyesight the earth has ever witnessed with eye sight over 13 times more clear than a humans. The first clue of this is the fact Tyrannosaurus had front facing eyes, meaning it had perfect depth perception. We know this because of the recreation of the eyes based on the fossil skull, eye sockets, which indicated its eye was the size of a softball. T. rex’s binocular range was 55 degrees which is actually greater than that of a hawk, which is of course renowned for its remarkable vision. Mix this eyesight with a sense of smell better than a bloodhounds, and a complex bird brain, this would be a perfect predator. Tyrannosaurus needed all these advantages as its pray was far from defenseless. Its pray would have included Ankylosaurus, Triceratops and Hadrosaurus which all have hard armor or a thick tail to ram into the predator to hit it off its feet. Tyrannosaurus rex lived in North America about 70-66 million years ago in the Hell Creek formation that leads from Montana to Colorado and branch off into Utah and Canada. During the time of Tyrannosaurus, the Environment of Hell Creek was a flood plain, creeks, swamps and dry forests of conifer trees and ferns that dominated for millions of years. The Swamps were home to many creatures such as crocodiles, fish, lizards, small non-avian dinosaurs, amphibians, mammals and birds. Away from the swamps, you would find dry forests and plains, which had creatures such as Tyrannosaurus, Triceratops, Dakotaraptor, Pachycephalosaurus and an uncountable number of others, not including the thousands of plant and fungi species. Meanwhile giant pterosaurs roamed the sky, and giant marine lizards swam the oceans. All of this was the domain of the mighty Tyrannosaurus rex, an invasive species from Asia that came to America during the early cretaceous period through land bridges and shallow seas. They became the top predator, and knocked other predatory theropod dinosaurs off the throne of Top Predator. Tyrannosaurus, despite popular belief, was covered in soft downy feathers much like emus and ostrich. They only really had scales on the under side of the tail, while their legs and face would have skin like an ostrich leg. They also did not roar, and most likely cooed and/or quacked like a modern day bird. They cared for their young like a mother bird and would defend them from anything. The closest living relative of the Tyrannosaurus is now the Chicken, and it may surprise you to know Chickens can chase, catch and devour mice whole, much like the Tyrannosaurus assumingly. For the very last thing you need to know the T.rex comes from a group of animals called the Tyrannosaurids, this group includes the Dilong, Gorgosaurus, Albertosaurus and Tarbosaurus.
  18. Did i find a dinosaur bone?

    I was raking leaves in the backyard, and in the water of a tiny stream in the wooded/swamp area i found what appears to be a large, petrified bone of some kind. Who can tell me what it is? Its hard and brittle like rock and ive found native american artifacts in the same area. Found in Channahon, Illinois.
