Newly discovered meat-eating dinosaur could be largest ever

Nov. 22 (UPI) -- A dinosaur recently discovered in Utah could be the largest carnivore dinosaur ever. The Siats meekerorum, or man-eating monster, was only a juvenile and makes scientists believe the beast was at least 30 feet long and weighed 9,000 pounds, meaning a fully grown Siats would be larger.

“Siats still had a lot of room to grow, and there is only a 4-inch difference between the estimated femur length of a juvenile Siats and an adult Acrocanthosaurus (the second largest predator in North America), so we think a safe estimate for an adult Siats is that it at least vied with Acrocanthosaurus (11,000 pounds) for the No. 2 slot,” lead author Lindsay Zanno told Discovery News.
