The dinosaur of the day: Glacialisaurus

Massospondylid sauropodomorph that lived in the Jurassic in what is now Antarctica Fossils were found in the 1990s by Dr. William R. Hammer of Augustana College and a team Found in the lower part of the Hanson Formation, in Mount Kirkpatrick Fossils were found at an elevation of more than 13,000 feet (~4,100 meters) Had to remove the bones from ice and rock, using jackhammers, rock saws, and chisels Known from a partial foot and referred material of a left femur Described in 2007 by Nathan Smith and Diego Pol Type species is Glacialisaurus hammeri Name means “icy lizard” or “frozen lizard”, and refers to the Beardmore Glacier region in the Central Transantarctic Mountains, where the fossils were found Species name is in honor of William Hammer First sauropodomorph found in Antarctica Glacialisaurus shows how early sauropods/sauropodomorphs were distributed (China, South Africa, South America, North America, Antarctica, probably due to connections between continents at the time) Other sauropod fossils have been found in the same formation, which shows that early sauropods and sauropodomorphs co-existed together for a while Herbivorous Estimated to be 20-25 ft long (6-8 m) and weigh 4-6 tons Predators at the time include Cryolophosaurus Its foot is similar to Lufengosaurus (lived in the Early Jurassic in China), which may have been a close relative
