Researchers have discovered a new species of carnivorous dinosaur that may be a direct ancestor of Tyrannosaurus rex.
Paleontologists have discovered fossils that belong to a new species of tyrannosaurs, and they may resolve a long-standing dispute among scientists about the evolutionary origin of tyrannosaurs, the famous huge carnivorous predators. Scientists believe that a new species of dinosaur may be a direct ancestor of the species Tyrannosaurus rex, writes Live Science.

Scientists from the Museum of Natural History in Dickinson, North Dakota, USA, presented a new study that described a new species of carnivorous dinosaur , which is related to the more famous Tyrannosaurus rex.
Scientists have carefully analyzed the fossilized remains, including fragments of the skull and skeleton, to come to the discovery of a new species of dinosaur. According to scientists, the species named Daspletosaurus wilsoni is actually a Daspletosaurus from the tyrannosaurid family, which includes the famous tyrannosaurus represented by the species T.rex.
Estimation of the age of the fossilized remains showed that this dinosaur lived approximately 76.5 million years ago, that is, 6 million years before the appearance of the tyrannosaurus T.rex.
The remains of the dinosaur were buried under a layer of hard rock at a depth of 8 meters, and they were discovered only thanks to a protruding piece of bone. Because it took a lot of effort for scientists to dig up the fossils, the new dinosaur was originally named Sisyphus. This is a character from ancient Greek mythology who, after cheating death twice, was forced to forever roll a huge stone up the mountain.
Paleontologists believe that Daspletosaurus wilsoni is a descendant of another species of daspletosaurus, Daspletosaurus torosus, and at the same time, it is the ancestor of another species of these carnivorous predators, Daspletosaurus horneri. Scientists believe that a new species of these earlier tyrannosaurs appeared between 77 and 75 million years ago. The anatomy of the new dinosaur supports the idea that daspletosaurs were the ancestors of Tyrannosaurus rex, scientists say.
Until now, the origin of the tyrannosaurid family has been difficult to decipher, and this has made it difficult to determine the exact evolutionary relationships between individual species. Many scientists disagree on whether tyrannosaurids have a single ancestry, and they appeared one after another, or whether several related species did not descend from each other.
But the discovery of a new species of Daspletosaurus suggests that the above three species of this predator appeared one after the other, as successive stages in a single evolutionary line, “and not branching off from each other. According to scientists, the species Daspletosaurus wilsoni is the missing link between the more ancient and later tyrannosaurs.
Given that these species could have evolved one after the other, scientists suggest that the rest of the tyrant nosaurids, including the most famous tyrannosaurus rex, could also have appeared in a similar way.
Focus has already written that scientists believe that Tyrannosaurus rex could have looked a little different than it is now believed . In particular, it could have been much larger.
