Australia had tree-climbing sheep-sized marsupials
Sheep-sized relatives of modern-day wombats were living in Australian treetops fifteen million years ago, a paleontologist stated Thursday as she was honored for her finding. Karen Black, from the University of New South Wales, said her group uncovered the world’s biggest tree-climbing marsupial among fossils located at the Riversleigh World Heritage Site in Queensland State. The seventy kilogram (154 pound) disported were most closely associated with wombats, a furry ground-dwelling creature exclusively located in Australia, Black who specializes in the diverse range and evolution of the country’s marsupials. Her researchers have highlighted a fifteen million-year-old cave which is littered with fossils and bones and includes well-preserved skulls as well as skeletons of the diprotodontoid marsupial known as Nimbadon.
The Nimbadon fossil material is an extremely uncommon and substantial resource, not just simply because it is so tremendously well-preserved, however, since it represents individuals from an array of ages from the little suckling pouch young to elderly adults. The Nimbadon materials have permitted the first detailed study of skull growth in a fossil marsupial along with brain progress and behavior. She said the animal might have been the biggest creature climbing trees at that time. (It) Possibly appeared a bit like a long-legged wombat,” she said. The presence of the cave found light in 2010. Black said it shown up animals plunged to their deaths through a vertical entrance which was obscured by vegetation.
The site is technically since it documents a critical phase of the evolution of Australia’s flora and fauna when lush greenhouse conditions were offering approach to a lengthy, slow drying out. The cave and its fossils are supplying an excellent legacy of clues regarding the environment fifteen million years ago,” she said. Black was accredited for her work Thursday when the Australian Academy of Science presented her the 2012 Dorothy Hill Award for female researchers in the earth sciences.
