Abstract

In the Lower Paleozoic (Cambrian-Middle Ordovician) sediments of the Macizo Hespérico numerous echinoderm fossils have been found (eocrinoids, homalozoans, diploporids, rombipherans, crinoids, and asteroids) in some exceptional conditions of conservation. This is due to the mineralized skeleton that these organisms present and the existence of some post-mortem processes that allowed this type of conservation.
