    • ‘Our cladistic analysis confirms that the taxa included form a solid clade based on the apomorphic presence of a diaresis on the exopod of the uropod.’
    • ‘A diaresis is also present on the exopod in the Laomediidae and in some taxa in the Axiidae.’
    • ‘The detailed structure of both exopods and endopods varied, both along the trunk of individual trilobites, and among different taxa.’
