List of stratigraphic units with dinosaur body fossils

This is a list of stratigraphic units from which dinosaur body fossils have been recovered. Although Dinosauria is a clade which includes modern birds, this article covers only Mesozoic stratigraphic units. Units listed are all either formation rank or higher (e.g. group). By preservation

By diversity Here the units are sorted by the number of genera that have been reported as being represented in their respective fossil yields. Since the creation or synonymy of genera can be subjective, the sorting of the units can only roughly approximate their known paleobiodiversities. Named genera of birds are included in biodiversity estimates.
