The Feliz Deserto Formation is a geologic formation of the Early Cretaceous age (Berriasian to Valanginian) in northeastern Brazil's Sergipe-Alagoas Basin. The formation belongs to the rift phase, in which a great lake formed.[1]
Background[edit]
The formation provided fossils of bivalve and gastropod molluscs, vertebrate remains of Lepidotes fish and teeth of crocodylomorphs and spinosaurids, the oldest of the family reported in South America.[1][2]
