Datu dibertigarriak

Siats was one of the largest predators in North America during the early Late Cretaceous, weighing about 3.9 metric tons (4.3 short tons).1

The only known Siats skeleton is from a young animal, not a fully grown adult, so it might have been even bigger.1 2

Siats lived at the same time and place as small tyrannosauroids, and scientists think it may have kept them from growing huge.2

The name Siats comes from a man-eating monster in Ute tribal legends from Utah.1 2

Siats is the first megaraptoran dinosaur ever found in North America.2

The fossil bones were found sticking out of a hillside during a 2008 expedition.1
