8 p, 1.9 MB Trilobites and intercontinental tie points in the Upper Cambrian of Scandinavia / Ahlberg, P. (Lunds universitet. Division of Historical Geology and Palaeontology)
The Upper Cambrian faunas of Scandinavia are generally dominated by olenid trilobites, which provide a firm basis for the biostratigraphic classification. The olenids tend, however, to be provincial and facies controlled. [...]

12 p, 1.3 MB Biostratigraphic significance of the latest Cambrian-earliest Ordovician agnostoid trilobites from Northwestern Argentina / Tortello, M. F. (Museo de La Plata (La Plata, Argentina). Departamento Paleozoología Invertebrados)
The biostratigraphic significance of the latest Cambrian-earliest Ordovician trilobite agnostoids from northwestern Argentina is summarized. A characterization of the faunas recognized below and above the Cambrian-Ordovician boundary is presented on the bases of information from sierra de Cajas (Jujuy Province, Eastern Cordillera; Lampazar and Cardonal Formations), río Volcancito (La Rioja Province, Famatina range; Volcancito Formation) and other localities assigned to the Parabolina frequens argentina Biozone.
