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.

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). Alejandra Alarcón M.

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.
