Abstract
A new Lower Pliocene crustacean assemblage is recorded in the southwes tern region of the Iberian Peninsula. This assemblage is of very low d iversity, being represented almost exclusively (96%) by specimens of G oneplax gulderi BACHMAYER, 1953 of the family Goneplacidae. Other fami lies represented are Callianassidae (Callianassa sp.), Laomediidae (Ja xea cf. nocturna NARDO, 1847) and Calappidae (Calappa cf. saheliensis VAN STRAELEN, 1936) as well as Portunidae (sp. indet.). The similarity between the decapod faunas of the Mediterranean Late Miocene suggests that some Late Miocene Mediterranean decapods were also present in ne arby parts of the eastern Atlantic realm, thus surviving the Messinian crisis. Initially, this western realm comprised a sublitoral environm ent with relatively deep quiet waters near the shore. Subsequently, th e conditions became more energetic in a very shallow sublittoral setti ng.
