The finding contravenes the idea that dinosaurs were already declining by this time....an idea which was ridiculous on its face. Thanks TXnMA. :')

Cryolophosaurus Ellioti fossil:Here is the femur, upper leg bone, of Cryolophosaurus elliot still trapped in the rock matrix.
The remains of the Cryolophosaurus were found in the Hanson Formation with the remains of a very large prosauropod (related to plateosaurids like the Plateosaurus and Lufengosaurus), a small pterosaur, a mammal-like reptile (a tritylodont, which is a type of synapsid about the size of a rat), and another unknown theropod. There were also fossilized tree trunks two meters away. The site is about 4,000 meters (13,000 feet) above sea level. This supports the idea that, even at high altitudes, early Jurassic Antarctica had forests populated by a diverse range of species, at least along the coast, even though Antarctica was closer to the equator and the world was considerably warmer than today, the climate was still cool temperate. Recent models of Jurassic air flow indicate that coastal areas probably never dropped much below freezing, although more extreme conditions existed inland. Cryolophosaurus was found about 650 kilometers (400 miles) from the South Pole but, at the time it lived, this was about 1000km or so farther north.
