"This dinosaur was a colossal predator second only to the great Tyrannosaurus rex and perhaps Acrocanthosaurus in the North American fossil record," said Dr Lindsay Zanno from the North Carolina Museum of Natural Sciences and the Field Museum of Natural History, the lead author on the paper published in the journal Nature Communications.
The prehistoric giant is named Siats meekerorum. The genus name, Siats, refers to a cannibalistic monster from the mythology of the Ute Native American people. Its specific name acknowledges the Meeker family for their support for early career paleontologists at the Field Museum.
Siats meekerorum was over 9 meters long and weighed more than 4 tons. Despite its large size, the dinosaur is not a close relative of Tyrannosaurus rex and other tyrannosaurs.
