Montenat C. et al. (2006) Stratigraphie et paléoenvironnement des dépôts volcano-détritiques à dinosauriens du Jurassique inférieur de Toundoute (Province de Ouarzazate, Haut-Atlas – Maroc) // Eclogae Geologicae Helvetiae, vol. 98, no. 2, p. 261-270.

The Early Jurassic dinosaur site of Toundoute which yielded the basal sauropod Tazoudasaurus naimi is examined in the light of its stratigraphic, sedimentological and palaeoenvironmental context. A thin succession of Early Liassic marine carbonates (probably Hettangian-Sinemurian in age) is continuously overlain by continental beds with dinosaurs. These latter are assumed to be of Middle to Late Liassic age. The continental deposits include a large part of volcanoclastics, different from the Triassic basalts. The Jurassic volcanoclastics originated from an unknown but obviously close eruption centre. The continental sediments (channels and flood plain) were deposited under tropical climate conditions with alternating humid and dry episodes. The bones occur as isolated or partly articulated elements (parts of carcasses). The two bone-beds are related to typical mud-flows. This type of transport protected the bones from erosion, and favoured their burying and fossilization
