Where: Centro, Portugal (39.5° N, 9.2° W: paleocoordinates 33.6° N, 1.2° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Lourinhã Formation, Late/Upper Kimmeridgian to Late/Upper Kimmeridgian (155.7 - 145.0 Ma)
• "? middle Upper Kimmeridgian" in Galton 1991 but could be either Alcobaça or Bombarral Fm.
•
•Lourinhã Fm is considered late Kimmeridgian-late Tithonian and it incorporates the Alcobaça Fm (Kimmeridgian) and the Bombarral Fm (also known as Grés Superiores; late Tithonian-early Berrisian). Taylor et al. 2013 suggested the Lourinhã Fm be subdivided into members, but Mateus et al. 2017 proposed a revised stratiraphy of the Luisitanian Basin. The Alcobaça Formation is Late Kimmeridigan and overlain by the Lourinha Formation. The Lourinhã Formation is made up of the Praia da Amoreira and Porto Novo (late Kimmeridgian) members, Praia Azul member (latest Kimmeridgian–earliest Tithonian) and the Assenta member (late Tithonian-earliest Berrisian). The Lourinha Formation is overlain by the Porto da Calada Formation (Berrisian).
