The Upper Viséan rugose corals from Peñarroya-Pueblonuevo and El Casar (San Antonio-La Juliana Unit, Cordova and Badajoz) are described. Ten species belonging to eight genera have been identified. Axophyllid corals are dominant in the assemblage and fasciculate corals are also common. On the other hand, no massive rugosans have been collected. Occurrence of the genus Amygdalophylloides is recorded for the first time older than Serpukhovian with the description of the new species A. anticuum. Thus, the record of the family Geyerophyllidae is extended from Viséan to Permian.

130 isolated dental remains, one maxilar and four mandibular portions of Cainotherium have been described and studied from Alameda de Osuna, Middle Aragonian of the Madrid Basin. This study has allowed to confirm the presence of one small size Cainotherium specie cited for the first time in the Spanish record, Cainotherium cf. huerzeleri. Alameda de Osuna has been correlated to other Madrid sites belonging to the MN5 (local zone D).

The Potes Group (Pennsylvanian, Liébana Valley, Cantabria N Spain) is composed of a rhythmic succession of shales and sandstones and contain the Cosgaya Formation. The Cosgaya Formation is composed of organic limestones that show abundant algae and corals and locally form mounds. Those mounds are conspicuous at Las Ilces Section where seven microfacies have been identified: MF-1, Bioclastic wackestone with Donezella stabilizing patches; MF-2, Boundstone of stabilizing and supporting organisms; MF-3, Boundstone/Packstone of intraclasts and peloids; MF-4, Bioclastic Wackestone/Packstone; MF-5, Donezella Boundstone/Packstone; MF-6, Bioclastic and peloidal Packstone; MF-7, Mudstone/wackestone with calcisferas and ostracods. These microfacies correspond to diferent parts (or zones) of mounds formed by microbial communities, algae and corals and the close areas of them.
