The Argana Group is a Permian to Triassic geological group in the western High Atlas northeast of Agadir, Morocco.[1] Sometimes known as the Argana Formation, it contains eight geological members often divided into three formations. They include the Late Permian Ikakern Formation (members T1-T2), the Early Triassic to Carnian Timezgadiouine Formation (T3-T5), and the Late Triassic Bigoudine Formation (T6-T8).[2] Ornithischian tracks are geographically located in Marrakesh province.[2] Indeterminate theropod remains and tracks are geographically located in Marrakesh province.[2]
