More Antarctic Dinosaurs

RockDoctor writes "The highly respected palaeontology journal Acta Palaeontologica Polonica has published its December number for free access on the Web, with the headline paper concerning new discoveries of dinosaurs from Antarctica. (Paper here, PDF.) The first major part of these discoveries was made in 1991, when isolated bones of a sauropod (a relative of the Apatosaurus, formerly known as Brontosaurus) were found associated with a theropod (ancestor or cousin of Tyrannosaurus rex). The sauropod has been named Glacialisaurus hammeri (the reason for the genus name is obvious, and Professor Hammer led the field expeditions under 'extremely difficult conditions'). The herbivore was some 25 ft. long and weighed 4 to 6 tons; at the time of life, the area was between 55 and 65 degrees south, suggesting a climate similar to the Falkland Islands or Tierra del Fuego."
