Descrição
Resumo:Ammonoids and nautiloids from Margas del Forcall Formation, located in the Oliete sub-basin (Iberian Chain), were studied. Taphonomic, sedimentologic and biostratigraphic analyses were carried out. The fossil record of cephalopods is especially abundant in a layer made up of reddish limestone with elongated nodules that are usually covered by a ferruginous-manganese crust. These nodules are embedded in a micritc matrix where infaunal tiering is largely preserved. The biostratigraphic study has allowed recognizing Hambrovi Subzone and proposing a new bioestratigraphic position for this stratigraphic interval
