Rhino Fossil Group

　　The area within the banner is extremely rich in mammalian fossils. Paleontologists and experts from the United States, France, Sweden, the former Soviet Union, Japan, Canada, and other countries have come to conduct research. As a result, Siziwang Banner has become world-renowned as the "Hometown of Fossils."

　　In September 1991, a rhino fossil group dating back 8 to 5 million years was discovered at a brick factory located 3 kilometers south of Wulanhaote Town. Experts identified these rhino fossils as belonging to the species Chilotherium, forming a rare Chilotherium fossil belt in China.

　　The fossils are buried in red mudstone layers 5 meters below the surface. Preliminary surveys indicate that the fossils are concentrated in an ancient fluvial sedimentary layer about 5 meters wide and 30 meters long, distributed in a southeast-northwest trending belt. The exposed area covers approximately 150 square meters, with over 20 individual rhino fossils revealed, including 20 rhino skulls as well as spines, limbs, and more. These rhino fossil skeletons, preserved in their original geological strata—whether tangled together or layered atop one another—retain the original state in which the rhinos died. These precious fossils provide scientific evidence for studying the morphology, geographical distribution, paleogeography, and paleoclimate of Chilotherium.

　　Chilotherium is a mammal and a species from the late Miocene epoch of the Cenozoic Tertiary period. It preferred living in hot river and lake regions. It had a bulky body, no horns on its head, and two large lower incisors, making it a unique member of the rhinoceros family and also one of China’s and the world’s precious ancient animals. Visiting this site allows you to see firsthand the majestic form of these ancient creatures.
