The Areado Group is a Late Jurassic to Early Cretaceous (Tithonian to Albian; covering approximately 50 million years)^[1] geologic group in southeastern Brazil. The group was defined by Cardoso in 1968.^[2]

Various fossil theropod tracks have been reported from the aeolic sandstones of the group.^[3][4]

The group contains the following formations from young to old:^[5]

• Albian Três Barras Formation - eolian and fluvio-deltaic sandstones
