With smart searching methods and specifically constructed weapons, they perfected the art of killing even the most hazardous mammals.But unfortunately, the excellent success of our forefathers came at the cost of the other large mammals.It is well-known that various big types went extinct throughout the time of the worldwide colonization by modern-day human beings.

They include elephants, bears, kangaroos and antelopes amongst others.It is estimated that there are 6,399 species of mammals on the Earth, however the 139 extant megafauna were chosen in this study to evaluate how their populations altered over the past 40,000 to 50,000 years, when comparable big animals went extinct.The big mammals are likewise called megafauna– and are specified as animals weighing more than 44 kg when completely grown.
