The prehistoric people once genocated large mammals

According to Bristol University research, prehistoric people were the cause of massacres of massive kangaroo and giant koalas as well as rhinos in a very short time. They wiped out large animals in the period of 40,000 to 50,000 years ago.

Giant prehistoric Kangaroo.

Dr. Alistair, Department of Archeology and Anthropology, Bristol University, together with Australian National University colleagues (ANU) in Canberra analyze 60 large-sized bones and teeth excavated in Cuddie Springs, New South Wales .

Cuddie Springs has become the center of a debate about the era and the extinction cause of the giant kangguru in the region between Australia, where it finds remains of prehistoric humans and animal bones in sediments. These classes are defined as dating from 30,000 to 40,000 years ago. Particularly, animal skeletons have not been able to conclude about the existence period.

ANU researchers headed by Rainer Grün analyzed the bones and teeth of large animals at Cuddie Springs using their atoms marked with uranium and electronic magnetic resonance methods to date and conclude. animals extinct for at least 50,000 years.

That said, there is a simultaneous existence between prehistoric humans and giant animals, which are hunted by humans to the point of extinction when the first humans settled in the continent.

Dr. Pike said: 'The reason for the disappearance of large mammals in Australia, Europe and North America is a hotly debated issue. Some people believe that it is due to the climate change of the Ice Age, but most of the comments state the cause of excessive human hunting. '

'To understand which ideas are more plausible, we have developed a method of dating the skeletons by the radioactive degradation of the small amount of residual uranium contained in fossils. This method is particularly useful for places like Cuddie Springs, where old and new relics are mixed together due to erosion. On that basis we affirm the second hypothesis'.
