The phylogeny of cyclopygid trilobites
A new phylogeny of cyclopygid trilobites (Superfamily Cyclopygacea Raymond, 1925) is presented, based on an analysis of 47 genera and 63 characters. The majority-rule consensus supports a paraphyletic

Phylogeny of some Devonian trilobites and consequences for the systematics of Austerops (Phacopidae)
A comprehensive phylogenetic hypothesis for Devonian phacopid trilobites of the genus Austerops has not previously been proposed. We carried out a cladistic analysis of the 13 species and subspecies a
