Cryolophosaurus was the first named dinosaur from Antarctica. Paleontologists found its fossilized bones relatively close to the South Pole, and during excavation in an Antarctica summer, they endured temperatures that rarely rose above -4 degrees Fahrenheit. Cryolophosaurus is one of the fully-articulated specimens in Ultimate Dinosaurs, which opens at the Science Museum of Minnesota on March 1, 2014. The exhibition features a new and unusual breed of dinosaurs that evolved in isolation in the Southern Hemisphere.

Giganotosaurus, the Southern Hemisphere's answer to T. rex, may have been the largest land predator ever to have lived. Similar in size to T. rex, an adult Giganotosaurus was more than 40 feet long and weighed more than 13,000 pounds. Giganotosaurus and other giants from prehistory in the Southern Hemisphere are featured in the brand-new Ultimate Dinosaurs exhibition, which opens at the Science Museum of Minnesota on March 1, 2014.

Paleontologists have debated the function of the signature sail on Ouranosaurus' back. Some think it may have helped the animal regulate its body temperature or acted as a storehouse for fat and nutrients; others think it was a feature that made it attractive to other members of its species. Visitors to Ultimate Dinosaurs, which opens at the Science Museum of Minnesota on March 1, 2014, will meet Ouranosaurus and other prehistoric creatures who called the Southern Hemisphere home.

Amargasaurus is one of the unusual animals featured in Ultimate Dinosaurs, a brand new exhibition about the dinosaurs of the Southern Hemisphere that opens at the Science Museum of Minnesota on March 1, 2014. This sauropod from Argentina had twin rows of long spines running down its neck, perhaps to attract mates or protect itself from rivals.

Carnotaurus' name translates from Latin to "meat-eating bull," likely for the pair of horns on top of its head. The skeleton of Carnotaurus provided the first look at an abelisaurid, or short-faced, tiny-armed theropod from Gondwana, the supercontinent of the Southern Hemisphere after the break-up of Pangaea millions of years ago. Carnotaurus is one of the species features in the Ultimate Dinosaurs exhibition, which opens on March 1 at the Science Museum of Minnesota.
