Shanshan County

[2] The local geology and the desert climate made it possible to discover a number of important fossil sites in the area, including China's largest cluster of fossilized dinosaur tracks and China's largest dinosaur.

In 2008–2011, a team of German and Chinese paleontologists discovered and studied an "enormous" accumulation of Jurassic turtle fossils at a site they nicknamed "Mesa Chelonia", approximately 25 km (16 mi) NNE of Shanshan Town.

Then the skeletons were transported to the present location by a debris flow during a catastrophic rainfall event, forming a Konzentrat-Lagerstätte.

[5][6] According to the paleontologist Walter Joyce, the Shanshan find has more than doubled the total number of Jurassic turtle specimens known to science.

[5] On January 6, 2009, five well-preserved mummies of ethnic Han men who lived during the Qing dynasty were excavated at a construction site near the Flaming Mountains in the county.
