Asociación de equinoideos en las calcarenitas messinienses de Alcalá de Guadaíra (Sevilla, SO España)
The echinoid assemblage from the Messinian calcarenitic deposits of Alcalá de Guadaíra (Sevilla, SW Spain) has been studied. Six species have been recognised; Schizechinus duciei and Plagiobrissus costae are rather common. This association and its taphonomic signature suggest a shallow marine deposi...

| Sumario: | The echinoid assemblage from the Messinian calcarenitic deposits of Alcalá de Guadaíra (Sevilla, SW Spain) has been studied. Six species have been recognised; Schizechinus duciei and Plagiobrissus costae are rather common. This association and its taphonomic signature suggest a shallow marine depositional environment in the infralittoral, characterised by coarse detritic bottoms and variable hidrodynamic energy. This echinoid association corroborates the attribution of the studied sediments to the Messinian |
