The trilobita as a natural group
Historical Biology, 1989It has been claimed that olenellids, long regarded as trilobites, are more closely related to chelicerates than to the rest of the trilobite clade (Lauterbach 1980). This was based on an interpretation of the homologies of segmental arrangement in the thorax, and of the thoracic axial spine.

Reassessment of the Order Trinucleida (Trilobita)
Journal of Systematic Palaeontology, 2020Trinucleoids have been considered as a superfamily of the Order Asaphida, based on: a pre-occipital glabellar tubercle, a cephalic median suture in most ancestral forms, and the presence of broadly...

Evolutionary radiations In the Trilobita
1991Abstract Radiations have been understood in several ways; the trilobites have a good fossil record which can be used to examine these different usages. Supposed radiations in the sense of accelerated cladogenesis (especially involving higher taxa) are discussed at two important times: the basal Cambrian radiation; and the basal ...
