WThe Alcobaça Formation, previously known as the Guimarota Formation, is a geological formation in Portugal. It dates back to the Oxfordian stage of the Late Jurassic. It is an important source of information on the diversity of Late Jurassic mammals. Many of the fossils were collected from the now disused and flooded Camadas de Guimarota coal mine.
WThe Calcarios Micriticos da Serra de Aire is a Bathonian geologic formation in Portugal. Fossil sauropod tracks have been reported from the formation.
WThe Caranguejeira Conglomerate is an Aptian to Cenomanian geologic formation in Portugal. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
WThe Lourinhã Formation is a fossil rich geological formation in western Portugal, named for the municipality of Lourinhã. The formation is Late Jurassic in age (Kimmeridgian/Tithonian) and is notable for containing a fauna especially similar to that of the Morrison Formation in the United States and a lesser extent to the Tendaguru Formation in Tanzania. There are also similarities to the nearby Villar del Arzobispo Formation. The stratigraphy of the formation and the basin in general is complex and controversial, with the constituent member beds belonging to the formation varying between different authors
