The Quebrada Monardes Formation is a geological formation in Chile dating back to the Early Cretaceous. It was deposited in warm, arid to semi-arid conditions.[1] One portion (the Codocedo Limestone Member) preserves a perennial salt lake covering at least 1,500 square kilometres (580 sq mi); this lake dried up, leaving a large area of mudflats.[1][2] Fossils of iguanodontian dinosaurs[3][4] and ctenochasmatid pterosaurs[1][5] have been found in the formation.
