Tarbosaurus (pronounced /ˌtɑrboʊˈsɔrəs/ TAR-bo-SOR-əs; meaning "terrifying lizard") is a genus of tyrannosaurid theropod dinosaur that flourished in Asia between 70 and 65 million years ago, near the end of the Late Cretaceous Period. Fossils have been recovered in Mongolia with more fragmentary remains found further afield in parts of China. Although many species have been named, modern paleontologists recognize only one, T. bataar, as valid. Some experts contend that this species is actually an Asian representative of the North American genus Tyrannosaurus; if true, this would invalidate the genus Tarbosaurus altogether.

Tarbosaurus and Tyrannosaurus are considered closely related genera, even if they are not synonymous. Alioramus, also from Mongolia, is thought by some authorities to be the closest relative of Tarbosaurus. Like most known tyrannosaurids, Tarbosaurus was a large bipedal predator, weighing more than a ton and equipped with dozens of large, sharp teeth. It had a unique locking mechanism in its lower jaw and the smallest forelimbs relative to body size of all tyrannosaurids, renowned for their disproportionately tiny, two-fingered forelimbs.

Tarbosaurus lived in a humid floodplain criss-crossed by river channels. In this environment, it was an apex predator at the top of the food chain, probably preying on other large dinosaurs like the hadrosaur Saurolophus or the sauropod Nemegtosaurus. Tarbosaurus is very well-represented in the fossil record, known from dozens of specimens, including several complete skulls and skeletons. These remains have allowed scientific studies focusing on its phylogeny, skull mechanics, and brain structure.

  • @MrJoeyBrat Yeah. Though, Tarbosaurus is a beast and considered to be the top predator in its environment, it is by no means one of the largest. Although, it still has a very powerful biteforce, but not as powerful as T-Rex.

    I do like Tarbosaurus though, it is very interesting since it took the niche under a very hostile environment.

  • @MrTobyCure

    Yeah you were right man, I actually looked it up by now, and that was based on a VERY OLD estimate it's considerably smaller than T-rex and not even in the Top 10 largest flesh eaters that I know of. Tarbosaurus was on average about 33 feet (Still pretty big though!)

  • @MrJoeyBrat I hope you know that you're completely wrong about that statement about Tarbosaurus being larger than T-Rex. It was the "C-Rex" which is considered a Tyrannosaurus Rex that was approximately 46 ft long by estimates though it is not a complete skeleton.

  • Oh, and @SinfullyMyOwn he is your sun, right? LOL

  • @Rapator2, I think the picture at 1:22 was pretty cool. Picture rating: 10/10. :D

  • I thought my 6 year old son made up this dinosaur....He'll be glad to hear that I was wrong. LOL

  • Rapator2, u did a good job but u forgot the most famous picture of Tarbosaurus ever made, by Czech painter Zdenek Burian (just type it in on Google).

    Now that picture scared the heck out of me as a kid, and made me regard Tarbo as a far more fierce and frightening animal than T-rex. In fact, it was slightly larger at a maximum length of 46ft but its physical mass was probably smaller.

  • @dinoman888

    And t. rex was da tarbo of usa ;)

  • @bellthebeast7235

    Actually,Tarbo came before T-rex
