Suining Formation
http://dbpedia.org/resource/Suining_Formation an entity of type: WikicatChineseGeologicalFormations
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. However, these results were subsequently challenged, with suggestions that the age of the zircons was affected by metamorphism, and that the zircons clustering around 145 Ma near the Jurassic Cretaceous boundary are closer to the correct date.
