Six species have been recognised; Schizechinus duciei and Plagiobrissus costaeare rather common. This association and its taphonomic signature suggest a shallow marine depositionalenvironment 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 YR 2008 FD 2008 LK http://hdl.handle.net/10272/8168 UL http://hdl.handle.net/10272/8168 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
