The Mount Kirkpatrick , also Mount Kilpatrick , is an ice-free mountain in Antarctica , six kilometers west of Mount Dickerson . Mount Kirkpatrick is with 4528 meters the highest peak in the Queen Alexandra Range (Queen Alexandra Range) and also the highest peak of the entire Transantarctic Mountains .
The mountain was discovered by a team of four around the British polar explorer Ernest Shackleton while marching towards the geographic South Pole during the Nimrod Expedition (1907-1909) and named after Alexander Bryce Kirkpatrick (1865-unknown), a businessman from Glasgow who financed the expedition had supported.
Fossil finds on Mount Kirkpatrick
In 1994, William R. Hammer and William J. Hickerson published the scientific description of the theropod dinosaur Cryolophosaurus ellioti . Its fossils were found in 1991 by a group of researchers led by the US American Professor Hammer at an altitude of about 4,100 meters on the slope of Mount Kirkpatrick in the volcanic siltstone of the Hanson Formation. Further remains were discovered in 2003, and the expedition members recovered around half of the skeleton. The roughly six meter long, carnivorous Cryolophosaurus lived during the Lower Jurassic ( Pliensbachian ) about 190 million years ago, when today's Antarctic continent was still part of the southern supercontinent of Gondwana and the climate was much milder. Thus he is the oldest representative of the Tetanurae , the dinosaur group to which most theropods belong. It is the first dinosaur found and scientifically described in Antarctica. The name "Cryolophosaurus", which means "frozen comb lizard", refers to both the unusual find situation and a "comb" on the nasal , a bone along the middle of the skull above the upper jaw. In addition to Cryolophosaurus , Hammer and his team found other remains of dinosaurs, such as the bones of an original, massospondylid prosauropod in 2004 . Other fossils that have come to light include a single tooth from the right lower jaw of a tritylodontid and the thigh of a pterosaur .
