Abstract

Cathodoluminescence and microprobe analysis in monopleurid shells from Aptian � Lower Albian limestones in Ereño (Bizkaia) has allowed to us to realize that different rudist shells show different diagenetic responses in front of a similar degree of diagenetic alteration. Monopleurid shells show a relatively high diagenetic degree when compared to that of requienids. Early neomorphism processes were dissimilar for different shells. The relatively thin monopleurid prisms could allow a diagenetic alteration in a higher degree than that affected requienid shells.
