Shanwang National Geological Park

The Shanwang National Geology Park (simplified Chinese: 山旺国家地质公园; traditional Chinese: 山旺國家地質公園; pinyin: Shānwàng Guójiā Dìzhì Gōngyuán) is located in central Shandong province, People's Republic of China, about 22 kilometres (14 mi) from Linqu County.

[3] The fossils are found in the early-mid Miocene Shanwang Formation diatomite beds and are approximately 17 million years old.

They are noted for the prolific number of specimens found and the diversity of the species recovered, as well as the remarkable state of their preservation.

The fine grained diatomite strata have led to exquisite preservation of external body features such as outlines of skin, hair, scales and feathers, rarely seen elsewhere in the world.

[4] Animal fossils include insects,[5] fish,[6] spiders, amphibians, reptiles, birds and mammals.
