The Bayin-Gobi Formation (simplified Chinese: 巴音戈壁组; traditional Chinese: 巴音戈壁組; pinyin: Bāyīn Gēbì Zǔ) (also known as Bayan Gobi, or Bayingebi Formation) is a geological formation in Inner Mongolia, north China, whose strata date back to Albian of the Early Cretaceous period. Dinosaur remains are among the fossils that have been recovered from the formation.
