  Laguna Brava Formation (Argentina) | |
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]
