An enormous new species of predatory dinosaur has been discovered in the fossil beds of southeastern Utah, paleontologists say, a colossal carnivore that was the apex predator of its day even giving tyrannosaurs a run for their money.
An artists rendering depicts Siats meekerorum, (pronounced see-atch), which lived 98 million years ago in whats now southeastern Utah. (Jorge Gonzales)
Though just a juvenile, the newly found specimen measured some 9 meters long and weighed at least 4 tons at the time of its death 98 million years ago.
Adults of its kind were probably half-again as large, dwarfing the tyrannosaurs of its time, according to scientists.
But despite its familiar, T. rex-like build, this new species named Siats after a cannibalistic, mischievous monster of Ute legend was no tyrannosaur.
Instead, it was a member of the even rarer (and harder to pronounce) carcharodontosaurs, or shark-toothed lizards a family of outsized carnivores represented in North America by only one other species.

(16,191 posts)Bones grow from the ends, and most species with skeletons have some variation of the epiphyseal plate...basically the growth plates where the end is getting bigger. Once a skeletal species reaches adulthood, the plates harden and become solid bone.
You can often determine a juvenile skeletons maturity at the time of its death by the presence of these plates, and their relative size in relation to the bone.
