It is an extinct long nosed animal and is considered one of the ancestors of modern elephants. Fossils have been found in Eurasia, Africa, and the Americas, and they lived during the Miocene period. The species of the genus Megalophynchus were once considered a central link in the evolution of long nosed dinosaurs, but there are also many taxonomic controversies. Their lower incisors are usually elliptical or pear shaped, while the characteristics of cheek teeth are not specialized and have significant intraspecific variation. The discovery and study of the toothed elephant not only enriched our understanding of the evolutionary history of long nosed animals, but also provided important clues for understanding the relationship between modern elephants and other ancient long nosed animals.

The scientific name Deinoterium is a group of prehistoric mammals that lived from the Miocene to the Pleistocene, belonging to the order Longnose. Famous for its unique downward curved long teeth, which are different from the long teeth of modern elephants. They grow from the lower jaw and curve upwards, rather than from the upper jaw. Large in size, similar to modern elephants, but may have different behavioral and living habits. Fossils of terror elephants have been found in Africa, Asia, and Europe, indicating their widespread distribution. The reason for the extinction of this prehistoric behemoth is not fully understood, but it may be related to climate change and human activities.

The woolly mammoth, also known as the true mammoth, is a species of animal belonging to the mammoth family in the order Longsnout of mammals. It is covered in long hair and has a tall body. It existed during the Ice Age and is the most famous extinct elephant. Its body size is similar to that of the Asian elephant, but its hind legs are short and its entire body tilts backwards. As early as one or two thousand years ago, they were distributed in the northern parts of Eurasia and North America. The body shape is similar to that of modern African elephants, but it has long hair all over its body, a high head and forehead, curled and coiled incisors, and a large and dense number of molars. It is a herbivorous animal. It is an animal that was distributed around the world during the Stone Age and is now extinct.

Africanelephant: a genus of elephants in the family Elephantidae, order Longnose. Adult African male elephants are taller than 3.5 meters and can reach a maximum of 4.1 meters, weighing approximately 2.7 to 6 tons. Females are smaller than males, with a maximum recorded weight of 13.5 tons. African elephants are the largest mammals on land, with males and females exhibiting a binary sex (both sexes differ in body shape or physical characteristics). Both species of elephants in this genus are native to Africa and can live in various natural environments ranging from sea level to an altitude of 5000 meters, including forests, open grasslands, grasslands, thorn bushes, and semi-arid jungles.
