‘Shark-Toothed’ Dinosaur That Competed With T-Rex Lived in Present Uzbekistan 90 Million Years Ago

About 90 million years in the past, through the Cretaceous interval, a large dinosaur with ‘shark-like’ tooth lived in present-day Uzbekistan, a brand new research says. The carnivorous dinosaur was 7.5-8 meters lengthy and weighed 1,000 kilograms – barely longer than an African elephant and heavier than two full-grown water buffaloes. The researchers have been amazed on the monster’s dimension because it was a lot bigger than the ecosystem’s beforehand recognized apex predator: a tyrannosaur. The researchers found it was virtually twice as lengthy and 5 instances heavier after learning the jawbone.

The findings have been printed within the journal The Royal Society this week, and the researchers named the beast Ulughbegsaurus uzbekistanensis. bipedal, with a big head, brief forelimbs and sharp claws. It was a “shark tooth” dinosaur aka carcharodontosaur. These carnivores have been associated in addition to rivals to the tyrannosaurs, whose species is named the T-rex..

Researchers say Ulughbegsaurus – One Theropod is characterised by hole bones and three-toed limbs – presumably the biggest carnivore on the time. And small tyrannosaurs that lived in the identical interval would have been 1/fifth their physique mass. It’s nonetheless a thriller what brought on Ulughbegsaurus to turn into extinct, however its disappearance led to the tyrannosaurs rising stronger and turning into the dominant predator in Asia and North America.

The researchers famous that this was the primary carcharodontosaur (shark-toothed dinosaur) found in Central Asia. Different dinosaurs, just like the tyrannosaurs, lived in the identical time and place, however they have been a number of instances smaller than Ulughbegsaurus. The discover can be the final recognized incidence of a carcharodontosaur and a tyrannosaur dwelling collectively in the identical geographical space. The researchers hope that this discovery will open up extra information about that interval.
