Environment
Lithology: conglomerate
Taphonomic context: fluvial deposit
Habitat comments: Neogene sediments in the basin constitute "a megasequence of lacustrine and palustrine sediments deposited in the context of an alluvial plain, and dotted with local sabkhas" and the fossils are from the upper "conglomerate" member of the formation, which consists of "alluvial deposits: sandstone and especially conglomerates"
Methods
Life forms: ungulates,turtles,other reptiles
Sample size: 34 specimens
Years: 2010
Sampling comments: "The material was collected by amateur collectors" but "Some new specimens have been collected by the authors in December 2010"
"One part of the material (about 20 specimens) is kept in a private museum in Erfoud (Morocco), while the other part (about 126 specimens) is housed at the Faculty of Sciences Ain Chock of Casablanca (FSAC)"
cf. Struthio sp. eggshell fragments are also present
