...Bruce S. Lieberman Abstract A phylogenetic analysis was used to determine evolutionary relationships within the Early Cambrian superfamily Olenelloidea Walcott, 1890. Phylogenetic patterns within the suborder Olenellina Walcott, 1890, which contains the Olenelloidea and the Fallotaspidoidea Hupe...

...BRUCE S. LIEBERMAN Abstract This paper presents a phylogenetic analysis of the “Fallotaspidoidea,” a determination of the biogeographic origins of the eutrilobites, and an evaluation of the timing of the Cambrian radiation based on biogeographic evidence. Phylogenetic analysis incorporated 29...

Figure 2 —Phylogenetic supertree for basal eutrilobite taxa produced by combining the cladogram in Figure 1 with those in Lieberman (1998 , figs. 1 and 2, 1999a , fig. 23, and 2001 , fig. 1) where taxa labeled 1–4 belong to the Redlichiina, taxa labeled 5–17 belong to the “Fallotaspidoidea

..., 1993 ) and it is still problematic. The revision carried out by those authors and adopted in the Treatise on Invertebrate Paleontology (Palmer and Repina, 1997 ) considered two superfamilies: Olenelloidea Walcott, 1890 and Fallotaspidoidea Hupé, 1953 . Considerably different from previous schemes...

... this, Lieberman (1998) removed one superfamily that had traditionally been assigned to the Olenellina from that suborder, the Fallotaspidoidea Hupé, 1953 , in order to avoid making the Olenellina paraphyletic. The moroccan representatives of that superfamily have been recently comprehensively treated by Geyer...

... trilobites that the Fallotaspidoidea, included within the Olenellid Province, are phylogenetically linked to the Redlichiina. Thus, parts of the Olenellid Province, particularly Laurentia and Siberia (see Lieberman, 1999 , p. 177) may have faunas that are more closely related to the Redlichiid Province than...

... Macrobiofacies, appeared in the deep open shelf in later Atdabanian time. In the later half of the Atdabanian, representatives of the Fallotaspidoidea (mainly Judomia ) and Pagetiidae (principally Pagetiellus and to a lesser extent Hebediscus and Triangulaspis ) occupy both ecological niches and constitute...

... consistency indices of 0.5 or less. Relationships depicted within the Olenellina ( Fig. 2 ), such as the grouping of Fallotaspidoidea, are weakly supported. The Olenellina were undersampled in terms of the characters bearing on their internal phylogeny, here serving principally as outgroups. We refer...

... ; Jell and Adrain, 2003 ; Babcock and Peel, 2007 ). Lieberman ( 2001 ) found that taxa traditionally assigned to the Nevadiidae formed part of a paraphyletic grade between the Fallotaspidoidea Hupé, 1953 and [Olenelloidea Walcott, 1890 +Judomioidea Repina, 1979 ]; he termed that grade...
