Tarbosaurus bataar (Tyrannosaurus rex analog)

Age: Late Cretaceous (Late Campanian-Early Maastrichtian), 74 million years ago

The carnosaurian theropods include the largest terrestrial predators ever to have inhabited the Earth. They began to evolve as early as the Early Jurassic or even Late Triassic but flourished in the Late Cretaceous. At that time the largest carnosaurs of the genus Tyrannosaurus lived in both what is now Central Asia and North America. The Asian species Tyrannosaurus bataar (which is frequently assigned to its own genus Tarbosaurus) is smaller than its North American relative Tyrannosaurus rex. As the former is some more ancient than the latter, it suggests the genus could initially have appeared in Asia and then entered North America through the wide land
bridge connecting these continents in the Cretaceous.

tarbosaur teeth
The tyrannosaurs possessed a huge head with very large cutting serrated teeth,
very stout and rather long hind limbs, and fore limbs greatly reduced as typical of all carnosaurs.

The brain in this tremendous animal was unbelievably tiny in comparison with body size.

There is no agreement as to whether tyrannosaurids were active predators or
scavengers, nor can scientists agree on the function of their forelimbs.
Probably, these dinosaurs could form packs to hunt for
very large herbivorous dinosaurs, such as Saurolophus.
Thanks to its extremely imposing appearance, Tyrannosaurus has become one of the
principals in Speilberg's triumphal movies Jurassic Park and The Lost World.
However, don't be confused by the title: tyrannosaurids did not live
in the Jurassic Period, but only in the Late Cretaceous.
By the way- the famous scientist Jack Horner of the Institute of the Rockies
came to visit the exhibit in St. Louis. He is the technical advisor to Steven Spielberg.
