It was found in Utah and lived after Jurassic tyrannosaurs such as Guanlong. Despite not being bigger than T.rex, it was possibly one of the largest predators of it's area.
  2. Siats-Siats was named after a monster in Ute Mythology. It was said to be 30 feet although a few people claim it can grow bigger sizes. Although considered to be a carnosaur like Allosaurus, more recent studies showed just like other megaraptorans, it was possibly a tyrannosaur.
