According to the recent research, some of the giant mammals that we previously thought were extinct at the end of the last ice age could live longer. Brazil's fragments of dental fragments found that some species may be present in South America even 3500 years ago.
We hope that a theory has so far about the extinction of Megavaina
the IFLSCIENCE According to his report, he has long assumed that excavation scientists have assumed that giant mammals such as mammoths, giant lamps and sword tigers at the beginning of the Holosin era, almost. 11 700 years. However, due to the discovery of the results of new research, especially Mammoth Sophie, 4000 years old, researchers began to question.

The Fábio Henrique Cortes Faria's research team at Río De Janeiro Federal University analyzed eight Megavaina residue with the radioactive carbon era. Two of the teeth have proven to be a specialization in the puerama, and a taber animal called Xenorhinotherium Baiense, that it is much smaller than expected.
People and Megavaina can live together for a longer period than we thought before
the research According to these animals, even 3500 years ago, they can share their habitats with humans for a longer period of time than they previously believed. According to current knowledge, almost the first people. They came to South America 17-20 thousand years ago, and therefore the common life of men and giant mammals could last for thousands of years.
Previous research has already shown that some megafauna fossils may be 6000 years old or less, but the current discovery reinforces the opinion that the extinction was not uniform and that some species have been destroyed at a time other than their peers.
Did not human fishing lead to the extinction of giant mammals?
The new results raise additional questions about the causes of Megafauna extinction. Earlier, Overkill and Blitzkrieg theories indicated that human fishing and change in the natural environment led to the extinction of these species. However, according to the latest discoveries and research, this assumption does not necessarily stop. According to researchers, the extinction of giant mammals did not arise through one event, but as part of a longer process, which could have been affected by various environmental changes and human effects.
According to Mimila Meth, the environment scientist at Rio de Janeiro University, the Brazilian between tropical (Brazilian region), can be a kind of shelter for species that have survived more than their peers. As a result of climate change at the time, open fields can turn into a forest scene, which has stared at the animal habitats and may have contributed to their final extinction, Science news.
According to Fabio Varia, the Brazilian scientists have long adopted the dominant view of North America that the harsh hunting of Megavo caused their destruction. “We were very sure that Megafauna lived only until the beginning of the Holosin, to the point that we did not bother to determine the exact age of the excavations,” Faria said. “But now we have a lot of work to work,” he added.
