dc.description.abstractLos briozoos son buenos indicadores paleoambientales, principalmente en carbonatos de aguas marinas templadas y frías. Parámetros paleoambientales como temperatura, salinidad, energía del agua, carácter del sustrato y tasa de sedimentación se deducen de las asociaciones de briozoos. Los briozoarios se describen y utilizan con este fin, por primera vez, en las rocas del Oligoceno-Mioceno del Subbético Externo. Las calcarenitas y calciruditas con briozoos se depositaron a profundidades comprendidas entre unos 15 y 60 m, en competencia y relación lateral con otras facies ligeramente más profundas de foraminíferos bentónicos y rodolitosen_US
dc.description.abstractBryozoans are excellent paleoenvironmental and paleoclimatic indicators, particularly for temperate and cold-water carbonates. Bryozoan diversity, abundance, zooid morphology and colony growth forms, as well as their structures provide information on the physical controls on their habitat. Palaeoenvironmental parameters such as temperature, salinity, water energy, substrate characteristics, and sedimentation rate are inferred from the bryozoans assemblages. The bryozoarians are described and analysed for the firt time in the Oligocene-Miocene rocks of the External Subbetic (Betic Cordillera). The calcirudites and calcarenites with bryozoa were deposited at depths between 15 and 60 m, in competition with and laterally related to deeper benthic foraminifer and rhodolith faciesen_US
