The Ksar Metlili Formation is a geological formation in eastern High Atlas of Morocco, it is late Tithonian to Berriasian in age. It is approximately 80 metres (260 ft) thick and primarily consists of mudstone and sandstone, with thin calcareous beds.[1] One of these calcareous beds near the middle of the sequence is an important microvertebrate locality.[2] Subsequent to the original site, several other localities have been sampled. The depositional environment is thought to be near shore deltaic.[3]
