Lithology description: "Total thickness of the geologic section of this locality is about 71.5 meters, consisting of three parts: upper white part, middle red part, and lower white part. The lithological complex of these three parts does not differ from each other, all showing a fluvial depositional environment. The three parts were in interfingering relationship with one another. The paleocurrent shown by trough cross-stratification in the hard layers of sandstone in the section is from east to west, and from north east to southwest...The two dinosaur egg nests from the paleosol were found in a muddy fine sandstone layer close to each other."
Environment:fluvial indet.
