What are Some Pleistocene Animals?

The Pleistocene, also known as the Holocene (from 2,588,000 years ago to 11,700 years ago), was created by the British geologist Layle in 1839, and Forbes called the Pleistocene the Ice Age in 1846. Early period of the Quaternary in the geological age.

Most animal and plant genera in this period were similar to modern species. Notable features are the colder climate,

The Pleistocene is an era of drastic changes in the climate on Earth. High in the northern hemisphere,

Pleistocene was a period of active glaciers, 1846

Most animal and plant genera in this period are similar to those in 2012. Notable features are the colder climate,

The Pleistocene in Earth's history is comparable to the Paleolithic in Archeology. According to the nature of the fauna, the characteristics of the deposits and other environmental changes, the Pleistocene can be divided into early, middle and late periods. Some scholars have set the rise and fall of the Early Pleistocene at 3 to 1 million years ago, which is equivalent to the earliest stage of the early Paleolithic;

In the published "PLOS ONE", a paper was published by Wu Xiujie, associate researcher of the Institute of Palaeovertebrate and Palaeoanthropology, Chinese Academy of Sciences. By studying the ancient humans in Xujiayao (also known as Houjiayao) in the late Pleistocene in China, the researchers pointed out that the Pleistocene humans have an unusually high incidence of rare diseases, providing a basis for exploring the reasons for the extinction or replacement of the Pleistocene humans. New evidence.

The human fossil of Xujiayao was found in a long gully on the west side of Houjiayao Village, Yangyuan County, Zhangjiakou City, Hebei Province. The geological age is inferred to be an earlier period of the Late Pleistocene, between 104,000 and 125,000 years ago.

The individual reported this time was the Xujiayao No. 11 fossil specimen, which belonged to the middle and posterior part of the parietal bone of an adult. This specimen has an unusual feature: there is a very obvious abnormal perforation of about two centimeters behind the bone wall. This unusual feature caught the attention of researchers. After excluding other causes such as trauma, the identification showed that perforation is a rare giant parietal hole disease. Macropyramidosis is a congenital anomaly of the vascular system. Specimen Xujiayao No. 11 is the first case of giant parietal foramen found in Pleistocene humans.

Xinhuanet, Zhengzhou, March 7th (Reporter Guijuan) Luoyang City's Institute of Cultural Relics and Archaeology recently discovered the Meso-Pleistocene ancient human fossils at the Sunjiadong site. This is also the first time in Henan to find the Meso-Pleistocene elder (folk) It provides important materials for the study of human origin and evolution in East Asia.

The Henan Provincial Bureau of Cultural Relics invited relevant experts and scholars from the Institute of Palaeovertebrate and Palaeoanthropology of the Chinese Academy of Sciences, the Institute of Archaeology of the Chinese Academy of Social Sciences, and Peking University to visit and discuss the scene. Experts believe that the unearthed ancient human tooth fossils have a clear and reliable horizon and are well-preserved.

The Sunjiadong Paleolithic site is located on a cliff head on the south bank of Yihe River in Luanchuan County. The excavations of ancient human fossils, stone products, river pebbles, rich animal fossils, animal manure fossils, etc. were excavated this time.

Shi Jiazhen, director of the Luoyang Institute of Cultural Relics and Archaeology, said that it was particularly important to find six ancient human teeth, two of which were young teeth, one incisor and three molars, and included two broken gums. On the whole, the teeth are relatively complete and not worn very badly. Some even young individuals do not grow out of the gums. Regardless of the size or the shape of the occlusal surface, the saved morphological information is clear.

Li Zhanyang, a researcher at the Henan Provincial Institute of Cultural Relics and Archaeology, said that judging from the types of unearthed fossils, the Luanchuan people should be about the same age as the Beijing Ape-Man and belong to the Middle Pleistocene in the geological age. If this site is in the same period as the Beijing Ape-Man Site in Zhoukoudian, the highest dating of the Beijing Ape-Man site is 730,000 years ago. The dating of the Luanchuan people may not be later than that of the Beijing Ape-Man. Earlier.

Gao Xing, a researcher at the Institute of Palaeovertebrate and Palaeoanthropology of the Chinese Academy of Sciences, believes that although the Middle Pleistocene Homo erectus fossils have been found in China and around the world, in fact, there are very few materials, and many of them are blank in many periods. The discovery of the Sunjiadong site not only fills the gaps in the Central Plains region, but also makes the human chain more complete. More importantly, this batch of materials is very informative, solid and of academic value.

Very clear.

Experts believe that dozens of vertebrate fossils have been unearthed at the Sunjiadong site, which is expected to become one of the important animal fossil groups in China, which is of great significance for the study of the evolution of paleontology and the change of the paleoclimate environment in China; Luan Chuan is located near the north-south geographic boundary of China. It plays an important role in studying the species and characteristics of the fauna in this transitional region during the Middle Pleistocene period, and provides important information for the evolution of animal geography and changes in the paleoclimate environment.

According to Researcher Li Zhanyang, Homo erectus is commonly known as ape man, and Homo erectus fossils have been unearthed in Africa, Asia, and Europe. The most familiar people are the Beijing ape man, also known as the Homo erectus. The life stage of Homo erectus is from about 2 million years ago to about 200,000 years ago. It belongs to the Pleistocene of the geological age and is mainly distributed in the Middle Pleistocene. ^[5]
