Areado Group (Brazil)

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]}

Stratigraphy

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

• Albian Três Barras Formation - eolian and fluvio- deltaic sandstones
• Aptian Quiricó Formation - lacustrine claystones
• Tithonian- Barremian Abaeté Formation - fluvial conglomerates
