abstract = {Serravallian (middle Miocene) coralline algal assemblages at the southern
margin of the Guadalquivir Basin (southern Spain) occur as rhodoliths
preserved in situ or very close to their growth habitats
(autochthonous–parautochthonous assemblages) and also as reworked
remains (allochthonous assemblages). The former assemblages consist of
spherical rhodoliths built up by encrusting to warty plants and also of large
fragments of branches, whereas the latter are mostly unrecognizable small
fragments occurring in channeled packstone–grainstone beds. In both cases,
the most abundant components are members of the order Hapalidiales
(Mesophyllum roveretoi, Mesophyllum sp., Lithothamnion ramosissimum,
and less frequently Phymatolithon group calcareum and Lithothamnion
group corallioides). Laminar growths of Lithoporella minus and branches of
Spongites group fruticulosus and Sporolithon sp. occur very rarely. There are
also anecdotal records of Subterraniphyllum thomasii, extending its upper
stratigraphic range up to the Serravallian in the western Tethys. The
autochthonous–parautochthonous coralline algal assemblages formed in a
middle ramp, at several tens of meters of water depth, as suggested by the
dominance of Hapalidiales. The allochthonous assemblages represent
fragments of coralline algae derived from the middle ramp and redeposited
in deeper settings, most likely the outer ramp, due to storm-generated currents.},
