Eccaparadoxides? pradoanus and Eccaparadoxides mediterraneus are both widespread trilobite species described from
the middle Cambrian of the Mediterranean region. Analysis based on a pooled sample of 500 specimens demonstrates
that many of the characters that have been used to define these species show continuous variations, some of which are
related to ontogeny. In addition, morphometric analyses of metric characters show that the two species cannot be distinguished
on the basis of these characters either. Many of the characters studied herein are widely used in definitions
and descriptions of other paradoxidid species, which suggests that the taxonomic classification of other paradoxidids
may be oversplit.
