The Suining Formation (simplified Chinese: 遂宁组; traditional Chinese: 遂寧組; pinyin: Suìníng Zǔ) is a geological formation in China whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. A 2019 paper shows zircon dating of the Suining Formation with a much younger age for the classically thought of Late Jurassic formation; the average age of the dating being roughly 114 myo or late upper Aptian.[1]
