The Toundoute Continental Series is a geological unit in Morocco. It is a terrestrial deposit which overlies marine dolomites of equivalent age to the Lias Group of Europe. It is dated to the Pliensbachian to Toarcian stages of the Early Jurassic by equivalence in stratigraphy with the Azilal Formation and Wazzant Formation. The dinosaurs Tazoudasaurus and Berberosaurus are known from the unit.

Lithology

Stratigraphy

The lithology of the unit is divided into 5 units from D to H, (A-C represent the units of the underlying marine dolomite, with C representing a transition to terrestrial environment).^[1]

Stratigraphy of the Toundoute Continental Series
Unit	Lithology	Thickness (metres)	Dinosaur fossils
Alluvium	Holocene conglomerate
H	Clay-sandstone series	≥ 100
G	Clay-sandstone series, with gypsum layer present at the top, just below this a second dinosaur bearing is present with very similar lithology to unit F.	50	Tazoudasaurus, Berberosaurus
F	Greenish grey clay-marl, detrital gravel to pebble sized clasts with lignite and bones.	≤ 5	Present, indeterminate
E	Alternation of red brown clay, fine sandstone and sandstone coarse conglomerates	100
D	Clay, fine sandstone and conglomerate, large volcanic rocks present	80
