Moradi Formation

The Moradi Formation is a geological formation in Niger. It is of Late Permian age. It is informally divided into three subunits. The lower portion of the formation consists of red mudstone, with muddy calcareous sandstone and quartz-granlule conglomerate present as lenses. The middle portion consists of muddy siltstone in thick beds interbedded with red argillaceous sandstone. The lower two thirds of the upper portion of the formation consist of red siltstone intercalated with channel lag intraformational conglomerates, while the upper third consists of barchanoid shaped lenses of conglomeratic sandstone with ventifacts. These facies are indicatived of deposition under arid conditions, with less than of annual rainfall in the Central Pangean desert, with annual temperatures of , but with ephemeral water presence including lakes.
Fossil content.
The formation is known for its fossils, including the temnospondyls "Nigerpeton" and "Saharastega, "the pareiasaur "Bunostegos, "the captorhinid "Moradisaurus," as well as a large indeterminate gorgonopsid."" Dicynodonts, widespread in other contemporary deposits, appear to be absent, with previous reports being in error.""
