geological formation in Morocco
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]
