Surprising truth about the new 'tyrant Nano' monster remains

After nearly two decades of research, scientists from Oklahoma State University (USA) have found the final answer for the Cretaceous "monster" once thought to be an entirely new tyrant dinosaur. - Nanotyrannus.

According to a recent publication in Science Advances , the mysterious Nanotyrannus is actually just . adolescent Tyrannosaurus (T-rex) .

Tyrannosaurus, the most terrifying monster that ever roamed the Earth.

The fossilized remains of a monster called Nanotyrannus have been found since the 1960s, believed to be an immature T-rex. However, in 1970, another study triggered a series of studies claiming it was actually another species, resembling a T-rex but smaller in size.

Finally, a study gave birth to the name Nanotyrannus, a hybrid of "nano" and "Tyrannosaurus" with the implication of a small tyrant dinosaur.

But suspicion arose when two skulls named Jane and Petey of the "Nanotyrannus" monster were unearthed in 2000. Scientists from the Center for Health Sciences (University of Oklahoma) spent years. to analyze, compare and contrast, so that today can confirm that Jane and Petey are completely T-rex reputation!

Jane has a nearly complete skull and skeleton, while Petey has a complete skeleton and a defective skull . "Our study independently tests the" Nanotyrannus "hypothesis using bone histology, instead of bone morphology," explains lead author Holly Woodward.

It is the bone tissue structure that shows growth at the time of death, as well as determining whether it is an adult animal. The result was solid: Jane and Petey were just babies, dying before they could enter the "roll" stage to transform into a giant tyrant dinosaur.

Jane and Petey were only 13-15 years old when they died, weighing about 975-1,000kg and only about 6m long, which is half the length and 1/10 of the weight of Sue, the largest tyrant dinosaur ever declared. excavation. The violent dinosaur is said to reach its maximum size by the age of 20, which is also the age of Sue at death.
