Fossils of the tyrannosaur ancestor of the family Tyrannosaurus

With the excavation of large-scale ancient fossils around the world, more and more ancient fossils have been unearthed. According to the latest news: Archaeologists have unearthed a new type of dinosaur in the Sahara Desert, the world's largest desert. The fossil is more than 8 meters long, has shark-like sharp teeth and dangerous brows, and is particularly good at tearing apart prey. Researchers believe that this dinosaur is likely to be the ancestor of the ferocious Tyrannosaurus.

Bristol biologist Steve Brusatte and University of Chicago paleontologist Paul Sereno discovered two 110-million-year-old species in the Sahara Desert of Africa. Cretaceous carnivorous dinosaur fossils, both of which were more than 8 meters long. They were the first carnivores to dominate Africa, South America, and the South Asian subcontinent during the Early Cretaceous.

It is reported that one of them is named "Kryptops palaios", which has a short nasal bone and a horn-like covering on its mouth. The teeth are very small and they mainly feed on animal carcasses or dying animals. Another species, named Eocarcharia dinops, had tall frontal bones and shark-like teeth. This type of teeth is more suitable for attacking live prey and causing fatal wounds to the prey's body.

The huge brow bone of "Eocarcharia dinops" almost covers its eyes, making it look very fierce and terrifying. When fighting for a mate, their huge brow ridges serve as a powerful "battering ram". This dinosaur is a type of carcharodontosaurus and is the most powerful carnivore in the southern continent. "Eocarcharia dinops" is likely the ancestor of the tyrannosaurus that lived in the late Cretaceous period. Speaking of the species Tyrannosaurus, it was once the most powerful land carnivore in the world, the ruler of a generation, and the nightmare of many dinosaur populations.
