The Bombarral Formation is Late Jurassic geologic formation in Portugal. The formation has produced the remains of multiple vertebrates,including non-avian dinosaurs. It was deposited during the Tithonian of the Jurassic period.
Stratigraphy and paleoenviroment The Bombarral Formation outcrops around Pombal, Portugal. It is considered a laterally equivalent but distinct rock sequence to the more well known Lourinhã Formation. It is interpreted as being deposited during the Tithonian of the Late Jurassic period. Its Lithology is primarily represented of massive fine-grained, micaceous sandstones that are mixed with red mudstones. It is interpreted as having been formed in a floodplain ecosystem.
