Largest Predatory Dinosaurs dDcarcharodontosaurs

The fact that Tyrannosaurus rex, not the biggest dinosaur in the world, the fact is that the biggest and strongest carcharodontosaurs but extinct first

A new species of carnivorous dinosaur , one of the three largest species ever found in North America , live and compete with tyrannosaurs that has a smaller size . Precisely 98 million years ago .

This newly discovered species , named Siats meekerorum , a supreme predator in its time . He managed to scuttle tyrannosaurus reach the position of top predators for millions of years.

Siats including species of Carcharodontosaurus , giant meat-eating dinosaur groups . The only other Carcharodontosaurus were found in North America is Acrocanthosaurus that roam eastern North Ameria around 10 million years earlier .

Siats itself a second Carcharodontosaurus ever found in North America . Acrocanthosaurus were discovered there in 1950 was the first .

"It's been 63 years have passed after the size of a predator species are found in North America , " said Lindsay Zanno , a paleontologist at North Carolina State University . Zanno and colleague Peter Makovicky , of Chicago 's Field Museum of Natural History , found the first bone portion of this predator in the year 2008.

The specimens were found to belong to an animal estimated size of over 9 meters and a weight of at least 4 tons . Although quite large , however, these bones are the bones of a young dinosaur .

Zanno and Makovicky estimated , Siats adults can have a size of Acrocanthosaurus . That is , the two species are competing for menadi second largest predator ever found in North America .

Tyrannosaurus rex , despite being the largest predator and weighs two times heavier than the predators , new roamed the Earth about 30 million years later .

" This size difference indicates that tyrannosaurs stunted by carcharodontosaurs , and can only grow bigger and become major predators after the carcharodontosaurs extinct , " said Makovicky .

Zanno added , tyrannosaurus is no more just a nuisance for Siats . " Just like a wolf when the lion managed to kill prey . Upon carcharodontosaurs destroyed , then the world is ruled by T. rex , " he said
