Abu Agag Formation (Egypt)

The Abu Agag Formation is a Turonian geologic formation in Egypt and Sudan. Indeterminate fossil ornithischian tracks have been reported from the formation.[1]

Description

The formation comprises intercalated sandstones and highly bioturbated sand- and siltstone layers which are horizontal and wavy bedded. Horizontally laminated and thin bedded fine-grained sandstones as well as flaser- and ripple cross-lamination characterize a low-energy environment within this fluvial succession.

Fossil content

The following fossils have been reported from the formation:[2][3]

• Planolites sp.
• Rhynchosauroides sp.
• cf. Rotodactylus sp.
• Scoyenia sp.
• Spirodesmos sp.
• Dinosauria indet.
• ?Ornithischia indet.
