Megacauda sungei fossil discovery in China

Overview

Researchers have identified a new species of Jurassic mammaliaform, Megacauda sungei, through fossil discoveries in the Inner Mongolia Autonomous Region of China. Living approximately 165 million years ago, the creature is described as the oldest known mammal relative to exhibit a semi-aquatic lifestyle, similar to a modern platypus or otter.

The fossils, found in Ningcheng, include well-preserved impressions of skin, fur, and skeletal structures such as the pelvis, hind limbs, and tail vertebrae. Measuring roughly 50 to 52 centimeters in length and weighing approximately one to two kilograms, Megacauda sungei is noted as the largest known member of the docodont mammal group.

Anatomical analysis reveals specialized teeth and fan-shaped canines, suggesting a diet of fish, invertebrates, and small prey. A significant finding involves the preservation of the throat and hyoid apparatus. These structures show similarities to modern therian mammals, indicating that advanced functions such as swallowing, drinking, and nursing had already developed in early mammalian ancestors.
