- The Silveirinha Formation is an Early Eocene (Ypresian, or MP7 or Neustrian in the ELMA classification) geologic formation of the in the Região Centro of central-western Portugal. The sandstones, siltstones and conglomerates were deposited in an alluvial environment. The formation has provided fossils of many mammals, birds, amphibians and reptiles, as well as mollusks and ostracods, and is considered one of the richest Early Eocene faunal assemblages of Europe. The taeniodont, typically known as a North American order; and the ostracod Cypris silveirinhaensis have been named after the formation. (en)
