The Hutuhbihe Formation, also known as the Hutubei Formation, 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. Body fossils of dinosaurs, pterosaurs, crocodylomorphs, and plesiosaurs have been recovered from the formation, alongside hundreds of fossil trackways.
