Found 14 elephant. It is estimated that they are between birth and two years old and weigh between 70 and 200 kilograms. The author also isolated 8 underage elephants (2-7 years old) and 6 underage elephants (8- 15 years old). Studies show that young people often encounter or show that this place is a breeding ground similar to sheep (there used to be a pond between sand dunes), and the surrounding vegetation can be used as a food source for elephants because they can't find other food for a long time. The author also found traces left by three adult women (15 years old or older) because they are very close to the footprints of small individuals.

Scientists from China led a group of Chinese and foreign partners to discover a more mysterious ruminant-a new fossil half-sniffing rat, which has a history of about 20 million years and was called "West Water Half-sniffing Rat" in recent research. This is the first time in China that the semi-musk deer fossils have been studied in detail, and it is concluded that early ruminants are territorial, which is expected to decipher the evolution process of ruminant horns. Elephants are the largest animals on the earth, and there is no doubt that they can be divided into three types: Asian elephants, African forest elephants and African grassland elephants. Their size and weight are all higher than those of other mammals on the earth, among which African grassland elephants are the largest, while adult African grassland elephants weigh between 5 and 8 tons, especially the larger ones.

According to reports, elephant fossils were discovered for the first time in the history of Zhuzhou City, "Sullenberg said. Then, while continuing the investigation, the team found some paleontological fossils, which experts initially estimated might be the fossils of cattle or rhinoceros. Zhang Tianyi, a professor-level senior engineer at the Provincial Institute of Natural Resources, said that it can be judged that some tropical animals and plants lived in this area for 6,543,800 to 40,000 years, and then disappeared due to climate and environmental changes.
