The Mazantic Shale is a geologic formation in Chiapas, Mexico.[1] It was deposited during the Early Miocene (Aquitanian). The formation comprises dark gray shales that were deposited in a marine environment. It preserves fossils, such as the turtle Allaeochelys liliae. Amber has been recovered from it.[2]
