Abstract
[Resumen] El alcance de las diferentes unidades litoestratigráficas del Devónico inferior-medio del Dominio Palentino ha sido muy variablemente interpretado. En este trabajo se discute la Formación Abadía como constituida por la sucesión que se extiende entre el techo de la Caliza de Lebanza y la base de la Formación Polentinos y se restringe el alcance del Miembro Requejada. Inmediatamente por encima del Miembro Requejada aparece un conjunto de Arnmonoideos con Erbenoceras, Mimosphinctes y Mimagoniatites estrechamente relacionado con la llamada «Fauna de Anetoceras» del Zlichoviense superior y enmarcado entre las biozonas de Dacrioconáridos N. barrandei y N. elegans (Zlichoviense) . Se discute el género Erbenoceras y las especies N. barrandei, N. elegans y N. cancellata y se describen Erbenoceras jilalense y Gyroceratites pallantianum n. sp.
[Abstract] Boundaries between the sucessive lithostratigraphic units of the lower-middle Devonian in the Palentine Domain, have been established in different ways. In this paper, the Abadía Formation is considered as consisting of the succession ranging between the top of the Lebanza Limestones and the base of Polentinos Formation. The range of the Requejada Member is also restricted. Overlying the Requejada Member an Arnmonoid series occurs bearing Erbenoceras, Mimosphinctes and Mimagoniatites. It is closely related to the so called Anetoceras Fauna of the upper Zlichovian and placed between the Dacrioconarid biozones of N. barrandei and N. elegans (Zlichovian). The genus Erbenoceras and the species N. ba"andei, N. elegans and N. canceIlata are discussed and E. jilalense and Gyroceratites pallantianum n. sp. are descrihed.
