Eastern High Atlas
Village of the eastern High Atlas
The eastern part of the High Atlas forms vast plateaux at high altitude which provide the headwaters for the Moulouya River. It extends from the town of Khenifra and includes oases at Jbel Ayachi (at 3747 m), Jbel Saghro and Jbel Sirwa (3305 m). This portion of the range includes the solid mass of the Tamlelt whose northern edge is occupied by its higher peaks, such Jbel Ayachi at 3,747 m. The altitude falls towards the east where the mountains join the pre-Saharan zone.
This massif became an internationally famous paleontological site after the discovery of the bones of the completely unknown ancestor of the dinosaurs, Atlasaurus, which populated Morocco 180 million years ago. This dinosaur is also named Tazoudasaurus, after the name of the village of Tazouda where it was discovered. The creature, about nine meters long, is postulated to be an ancestor of the Sauropoda found in America. Until 140 million years ago the African and American continents were connected.
