The analysis is one of them framework From 68 million years ago rewriting history T-rexThat fossil found in 2006 In montana and until recently was thought to be testimony to a fight between a triceratops and a young tyrannosaurus. New analysis results, published in the journal Nature, shows just that not a T-rex that challenges a triceratops, but a Nanotyrannusa species similar to Tyrannosaurus but smaller in size. Analysis conducted by Lindsay Zanno, of the University of North Carolina, and by James Napoli, of Stony Brook University, shows for the first time that T-rex was not the only predator of its timebut they have competitors.
Fossils discovered in Montana in 2006 showing a Triceratops specimen that resembled a small tyrannosaur immediately gained immense popularity, but forced us to revise much of our knowledge about T-rex. To make problem it’s there possibility that could happen this kind of struggleas it is believed That is me The young T-rex didn’t have much strength and fighting a triceratops is of course a very tough challenge.
By analyzing the fossil in detail, the researchers confirmed that the alleged T-rex, which was about 4 meters tall and weighed less than a ton, was actually a adult specimenabout 20 years old. Therefore, it is one new species calling Nanotyrannus. This discovery proves that T-rex were not indisputably unique predators, but they shared space with at least other similar species, much smaller but more agile and dynamic, so they could compete.
