The fossil find in Central Asia is giving the scientist the glimpse of the evolution process. It is giving them some idea of evolution and how it created a monstrous killing machine like the T.rex. Scientists have found that huge predators like. T.rex and other tyrannosaurs evolved from much smaller ancestors.
The fossil find in Uzbekistan indicates that this evolution happened very rapidly. The change in some anatomical featured may helped the Huge predator in hunting so effectively.
The Tyrannosaur found in Uzbekistan is named Timurlengia. It is 90 million years old. It has come from a point before Tyrannosaurs started to evolve into their huge size, reported BBC. The fossil has been discovered by US and Russian scientists working in Uzbekistan. They are expecting that the skull of the animal is going to reveal some of the secrets of its evolution.
The Science Daily has reported that the horse-size dinosaur fossil reveals how T.rex and its close relatives became great predators. Before the discovery of the small dinosaur, scientists have said that the evolution from small bodied species to fearsome predators like T.rex took 70 million years. But new studies based on the fossil find reveals that much of these transitions and growth in size happened suddenly.
The study also shows that before they evolved into massive killing machines, these pre-historic creatures had already developed keen sense and cognitive abilities; this includes the ability to hear low frequency sounds.
Hans Sues, chair of the Department of Paleobiology at the Smithsonian’s National Museum of Natural History, said, “Timurlengia was a nimble pursuit hunter with slender, blade-like teeth suitable for slicing through meat.”
He further stated, “It probably preyed on the various large plant-eaters, especially early duck-billed dinosaurs, which shared its world. Clues from the life of Timurlengia allow us to fill in gaps and better understand the life and evolution of other related dinosaurs, like T. rex.”
In yet another discovery, some scientists have identified an abeliseur from its bones left forgotten in a drawer at the Museum of Geology and Palaeontology in Palermo, Italy, this month.
