Geography
Country: Morrocco
Coordinate: 34.18216° N, -2.34992° W
Latlng basis: estimated from map
Scale: basin
Time interval: Late Miocene
Geography comments: "The region of Aïn Beni Mathar where the fossils were recovered is located in eastern Morocco in the northern part of the Hauts Plateaux"
Environment
Lithology: siliciclastic (mixed)
Taphonomic context: fluvial deposit
Habitat comments: "This river thus drains an erosive basin in the north of the Hauts Plateaux resulting from the excavation of ancient continental deposits composed of clays,
sandy or gypseous marls with calcareous episodes (sometimes with flints), and with an age between Oligo-Aquitanian and MioPliocene (Muratet, 1991)."

Sampling comments: collected by water-screening of approximately 400 kg of sediment obtained during archeological prospecting carried out in 2009 by an international team from
the Mohammed Premier University (UMP; Oujda, Morocco), the Institut Catala de Paleoecologia Humana i Evolucio Social (IPHES; Tarragona, Spain), the Rovira i Virgili University (URV; Tarragona, Spain), and the Centro Nacional de Investigacion sobre la Evolucion Humana (CENIEH; Burgos, Spain). All of the sediment was water-screened using superimposed 10, 5, and 0.5 mm mesh screens. In subsequent years, the microfossils have been processed, sorted, and classified into broad categories. The fossils are housed in the Musee Universitaire dArcheologie et du Patrimoine (MUAP; Oujda, Morocco)
