The Hutuhbihe Formation, also known as the Hutubei Formation,[2] is an Early Cretaceous fossil formation that is part of the larger Tugulu Group in Xinjiang, China. Pollen and clam shrimp assemblages present in the formation indicate a Valanginian age.[3] Body fossils of dinosaurs, pterosaurs, crocodylomorphs, and plesiosaurs have been recovered from the formation, alongside hundreds of fossil trackways.[1]
