Lead – The Tyrannosaurus Rex we know today really needs to be divided into three different species. Thus say researchers in the journal Evolutionary Biology. D. outside of North America. It can have effects on a single skeleton of the Rex, that is, on the skeleton of the Rex in Naturalis.

AD According to, the researchers looked at the front teeth in the lower jaw and the femurs of 38 known skeletons. It showed that there is a difference in size, so there will be three different species. They have already given the names of a third species that bears the name Tyrannosaurus imperator, Tyrannosaurus regina and Tyrannosaurus rex.

The skeleton of T-rex Sue in the Field Museum in Chicago will now be the T-rex Imperator, according to new researchers’ calculations. Stan’s skeleton sold for millions of euros to an individual named D-Rex Regina. What are the effects of Trix? Anyway, at least they didn’t go down without explaining themselves first. “Many colleagues say this research makes no sense, and I totally agree with it,” says researcher Ann Schulp.

‘A little big tooth’

“They looked at the smallest detail. A tooth with teeth that are slightly larger or smaller. But you can see how many similarities and differences there are within the species with every other dinosaur species. And here it is. It rarely differs and of course you can not talk about another species.”

‘If you randomly select ten people from the street and measure them, look at how long the legs and forelegs are or how thick the femur is, you will see a lot of variety,’ says Schulp. Yet we say: they are all Homo sapiens, they are all human.

‘Slightly different curls’

According to Naturalis researcher Schulp, there was also uncertainty about the number of organisms in the trichotillomania. ‘There was a head with horns in the trichoderma, and when a new skull was found with a horn on a slightly different spiral they thought it was a different species. Eventually they came up with nineteen species with different curls on the horns. But after thorough research, only two species survived. ‘

After all, nothing changes for the tricks in naturalism. Even if someone gives it another name, it’s just amazingly beautiful meat from the end of the dinosaur age, “says Schulp.” We’re not really going to separate it!
