Its name comes from the Greek and means alarming reptile. It is a tyrannosaurid dinosaur of which only one species is known, the Tarbosaurus Bataar. The Tarbosaurus lived at the end of the Cretaceous about 70 million years ago in Asia. The known fossils were found in Mongolia and others in parts of China. The Tarbosaurus is a little smaller than the Toranosaurus Rex, and yet it is one of the largest tyrannosaurids as it could measure up to 12 meters long and up to 5 meters high, only its skull measured about 1.3 meters much larger than the rest of the tyrannosaurids. One of the distinguishing features was that his eyes didn’t look straight ahead like the Tyrannosaurus, so he didn’t have the same binocular vision. It had about 65 teeth in its powerful jaws, more than those of a Tyrannosaurus and had a peculiar oval shape; the upper teeth were D-shaped. This characteristic is called heterodontics, which means that it had different types of teeth and is typical of tyrannosaurids.
The Tarbosaurus was discovered during an expedition to the Gobi Desert in Mongolia in 1946, the first thing found was a skull and some vertebrae. In 1955, Evgeny Maleev described the dinosaur and that same year three new skulls were found that helped to describe the Tarbosaurus. Although initially thought to be three different species, in 1965 it was discovered that they were Tarbosaurus only that they were different ages and therefore varied in size. After the first expedition many more expeditions continued until 1971, year in which many fossils of Tarbosaurus and other dinosaurs were found, the expeditions and findings continued until 1998, for this reason we have more than 30 known specimens, in fact it is one of the dinosaurs of which there are more remains and therefore is one of the dinosaurs that have been studied in greater depth.
The Tarbosaurus lived in a very humid environment, where there were many canals and rivers. It was undoubtedly the largest carnivore in the region and probably the highest in the food chain, probably fed on Sarulophus or Nomegtosaurus. What made him a very fierce carnivore were his teeth, he had very powerful teeth and the fact that they had different positions and shapes made them perfect to nail themselves to their prey and not let them go, he also had the advantage that when they were worn out they were replaced by new teeth.
Although his small arms were not able to hold anything, he could use his claws to finish his work. It is also believed that he could run quite fast, due to his ankle joint and the fact that he had large, strong legs and a tail that swung all his weight and allowed him to balance while running to catch up with his prey.
The Tarbosaurus was peculiar because of the enormous amount of teeth it could have, its jaw could have more teeth than any other Tyrannosaurid, the number of teeth reached 65, which made it one of the most powerful and frightening jaws of all dinosaurs. If we add to this that his teeth had the ability to grow back when they were worn out, this gave him a lifetime of hunting. Another peculiarity of his teeth was that they had different shapes and positions so that the strength of his bite was so great that it was impossible to escape it.
His head could be as big as a Lion or a Leopard. His most powerful weapon was his ability to hunt, he was not a very big dinosaur but this did not take away any power or ability to be a great hunter.
Tarbosaurus is commonly mistaken for Tyrannosaurus Rex, so it is not commonly portrayed with similar characteristics or instead of Tyrannosaurus. On many websites you can find interesting comparisons with the Tyrannosaurus. You can also see him in the BBC documentary Walking with Dinosaurs, in this documentary The Claw of the Tarbosaurus is of special attention and you can even see him fighting with a Teryzinosaurus.
