Abstract

Traditionally, the Late Devonian phacopines with reduced eyed, from deeper-water external platforms are integrated in the single taxon Cryphops, despite its discontinuous distribution in time. A new interpretation of phyletic relationships is proposed here, taking into account ventral cephalic characters that have hitherto not been considered. In this model, different lines leading to the "Cryphops" morphotype derived repeatedly and independently from the ancestral Phacops root stock by iterative evolution.
