The truth about elephants became extinct in China 3000 years ago
Scientists said wild elephants living in North China 3000 years ago Palaeoloxodon extinct species. Earlier, this elephant Elephas maximus allegedly species, an Asian elephant species still living in South China.
The findings of this elephant was published on page Quarternary International, conducted by scientists from the Shaanxi Normal University, Northwest University in Xi'an Research Institute of Geosciences and finance natural, Beijing.
Today, wild elephants do not live in North China, but historical documents show that they were free to go back 3000 years ago.
For decades, experts have said that wild elephants are E.maximous elephants - elephants only adapt to the tropical climate and is still living in Yunnan Province in southern China. They think that the North China influenced by the tropical climate at that time.
However, the results of this study later showed that most of northern China under the warm temperate zone and subtropical regions do not belong to 3000 years ago. "This means that temperatures in North China is not warm enough to E.maximus elephants can survive," said Li research group said.
Palaeoloxodon species are believed to have disappeared from their residence in China in transition between stages Pleistocene and Holocene century to 10,000 years ago.
To study whether these animals have lived through the Pleistocene to Holocene century did not, the researchers examined the fossil elephant teeth found in Holocene rocks in the 1990s. Scientists ago that they are fossil E.maximus. However, Li's team concluded that tooth and ivory tusks Palaeoloxodon species like the more straight.
The researchers also examined dozens of bronze elephant statue from the Zhou Dynasty, Li Shang after he noticed the trunk ornaments in this simulation are not the same as the species E.maximus.
Elephants can have one or two finger tap on top of them. 33 elephants were collected from various places around China have two fingers on the nozzle, while only one species E.maximus.
"Species Palaeoxodon one or two fingers in the nozzle is still not known, but certainly E.maximus species only one finger," Mr. Li said.
Age of the bronze statue reinforces the hypothesis of the researchers that Palaexodon species not extinct until a few thousand years after the time at which it was thought they were extinct.
Results of the study group is consistent with the recent findings that large mammalian species, including rhinos, mammoths, bison Europe, still exists to celebrate Holocene has not disappeared in Pleistocene.
