Shishugou Formation, Geological formation in Xinjiang, China.
The Shishugou Formation is a geological layer in Xinjiang containing multiple strata of mudstone, tuff, sandstone, and conglomerate from the Late Jurassic period. The rock layers preserve fossils spanning roughly 7 million years and form a detailed record of ancient life.
Scientific exploration of the site began in 1928 when a paleontologist identified dinosaur remains there. Subsequent expeditions between 1960 and 1990 systematically uncovered more fossils and expanded understanding of this rich fossil deposit.
Research teams from China and around the world study the fossil remains found here to understand dinosaur development and ancient environments. Their work reveals how life evolved in this region during the Jurassic period.
The site contains several well-defined rock layers that help researchers date fossils and understand their sequence through time. Access to the formation may vary depending on ongoing paleontological fieldwork at the location.
Natural pit structures within the formation contain stacked skeletal remains of meat-eating dinosaurs, suggesting specific group behaviors in the ancient past. These unusual accumulations provide insight into how these animals lived and interacted.
