mammal
It is the highest class of vertebrates, and its body is generally divided into five parts: head, neck, trunk, tail and limbs. Full of hair, raised at constant temperature, mostly viviparous, feeding young animals with milk. It was first discovered in Triassic, and the Cenozoic is extremely prosperous with many fossils. The mammalian fossils of Linqu Shanwang are famous at home and abroad for their diversity and typicality.

● Artiodactyl deer family

The ray triangle: the individual is small, and the lower posterior tip of the lower premolar is weak, without forming a closed inner valley. The upper molars are short and wide, and there are small folds in the posterior ridge of the original tip.

The buccal tooth band and attachment column are weak. The male has a pair of thick, short and flat "bony horns" located above the orbit. The leading edge of the corner is inclined backward, and the trailing edge is depressed forward before the base reaches the track. The base is located at the rear edge of the track. The top of the "skin bone angle" is slightly enlarged, and the surface of the angle is rough. The top of the pillow extends backward and upward, forming a "hammer-shaped" trumpet-shaped protrusion with an enlarged end. Produced in Miocene Shanwang Formation in Linqu.

● Artiodactyla

Lagomeryx colberti: The angle is close to the orbit and grows almost vertically above the orbit.

The picture shows a female rhinoceros fossil, giving birth with an embryo. The skeleton in the small rhinoceros's stomach is clearly visible, with its front legs bent, its rear legs pedaled to the ground and its head turned to the position of labor. The pregnant period of female rhinoceros is generally 15 ~ 18 months, and only one fetus is born at a time. Produced in Miocene Shanwang Formation in Linqu.

The fold of anterior cusp is weak, the original cusp of molar does not shrink, the anterior cusp is strong, the anti-anterior cusp is weak, and there is no small cusp. The limbs are slender, the forelimbs have four fingers, the middle part of the carpal bone is not connected with the ulnar joint, and the metatarsal surface of the talus has three wide and prominent articular surfaces.
