Cryolophosaurus

Cryolophosaurus ellioti

The first carnivorous dinosaur described from Antarctica, Cryolophosaurus ellioti carried a distinctive fan-shaped crest running crosswise over its head, which earned it the nickname Elvisaurus. Roughly 6.5 meters long and near 465 kilograms, it lived during the Early Jurassic, roughly 201 to 175 million years ago, when the southern continent lay in a far milder climate than today. William Hammer and William Hickerson reported it in 1994 from Mount Kirkpatrick. Its name means frozen crested lizard, a reference to both the transverse ornament and the icy locality where it was unearthed, and its discovery extended the known range of early theropods to the polar south.
