List of stratigraphic units with few dinosaur genera

This list of stratigraphic units with few non-avian dinosaur genera includes Mesozoic stratigraphic units of formation rank or higher that have produced dinosaur body fossils which have been referred to at most five genera. Since taxonomy frequently changes and can be somewhat subjective, the number of reported genera may not coincide exactly with the number of genera extant at the time of deposition.
