Extinct rugged climbing kangaroo found in Australia – science – life


Scientists have discovered an extinct kangaroo that is suitable for climbing with its powerful combination of forward and hind legs, arms and strong curved claws.

The study, conducted by Dr Natalie Warburton of Murdoch University and Gavin Bridax, a professor at the University of Blinders, found that the new species differs from all other kangaroos by having a very unusual pocket inside the nose.

“The samples we analyzed, including several skulls and almost two complete ones, were ‘slow-moving’ by this kangaroo species climbing trees,” Warburton said in a statement.

“By carrying out a rigorous process of identifying and describing the anatomical details of each bone recovered from the skeleton, we were able to reveal that these endangered vultures were suitable for climbing trees in search of plant material not available to animals. It provided a completely new explanation for the biology of the organism.”

The skeletons examined came from the Nullarber Plain Tylogolio and Mammoth Caves in Western Australia. They were invented in 2002 and 2003 by WA splinters Paul Devin and Eve Taylor.

“Although said to be an expert on fossil kangaroos, it took me a long time to realize that these two skeletons belonged to a species described decades ago from jaw fragments from a cave in southwestern Australia,” said Associate Director Professor Bridax. Polyandiology Laboratory at Blinders University in Adelaide, South Australia.

“Tilakolio Caves are famous for their significant preservation of fossil fossils and information on the diversity of unexpectedly large-scale marsupials, which now inhabit the dry wooded plains.

“This discovery is yet another reminder of how little we understand even the relatively recent geographical past in Australia,” he said.

Since all but one group of kangaroos live on the ground, and all the creatures known to climb trees (tree kangaroos) are closely related, the finding suggests that kangaroos climb the tree more than once.

These fossils have unusually long toes and toes with long, curved claws compared to other kangaroos and kangaroos; The powerful arm muscles that stand up in trees, the longer and longer mobile neck than other kangaroos, are useful for extending the head through the leaves in different directions, ”Warburton explained.

“It is very interesting, not only from the point of view of unexpected tree-climbing behavior in a large valley, but also because these models now come from an area where there are no trees, which tells us that the habitat and environment were very different from what we are now at the time, which may be different from what we described earlier.
