Laguna Brava Formation (Spanish: Formación Laguna Brava), formerly referred to as Santo Domingo Formation, is a Late Eocene (Tinguirirican in the SALMA classification) sedimentary formation located in the Argentine Northwest.[1] The formation contains beds with fossil bird tracks described as Gruipeda dominguensis.[2]
It was formerly thought that the formation was of Triassic age.[3]
