New Lower Cambrian trilobites from Pleistocene erratic boulders of northern Germany and Denmark and their bearing on the intercontinental correlation

Abstract

Auf Grund eines Versehens wurde die Abb. 4 im Beitrag GEYER et al. (Pal~iontologische Zeitschrift 78 (1): 127-136) falsch beschnitten. Daher wird an dieser Stelle eine korrigierte Version nachgeliefert.

The shelly fauna and biostratigraphy of the lower Cambrian (provisional series 2, stage 4) Evjevik Member, Ringstrand Formation in the Mjøsa area, Norway

“…This has been initiated by Geyer (1990), who reassigned most of the Scandinavian Proampyx species (see Ahlberg & Bergström, 1978) to Ornamentaspis and erected a new genus, Issafeniella, to which the wellknown Scandinavian species Strenuaeva spinosa may be assigned. Geyer et al (2004) described two new trilobite species, Epichalnipsus anartanus and Berabichia erratica, from erratic boulders supposedly deriving from the File Haidar Formation of southern Sweden. These taxa show affinities to western Gondwana and Geyer et al (2004) also tentatively assigned Proampyx rotundata (Kiaer, 1917) to Berabichia.…”

The lower Cambrian trilobite fauna from the Holy Cross Mountains in Poland consists of holmiids with strong Scandinavian affinities, while the associated ellipsocephalids show similarity to those found in West Gondwana (Żylińska, 2013, p. 62).…”

The oldest Cambrian trilobites from the Holy Cross Mountains, Poland: taxonomic, stratigraphic and biogeographic reappraisal

“…K. obliquoculatus Zone, thus indicating a younger level than its occurrences in Morocco (Westrop and Landing 2000). The faunule with Berabichia erratica Geyer, Popp, Weidner and Förster, 2004, from Pleistocene erratic boulders in a gravel pit Trilobite and acritarch assemblages from the Protolenus−Issafeniella Zone were defined and described in Żylińska and Szczepanik (2009); the acritarch assemblage from the Holmia−Schmidtiellus Assemblage Zone of the Kamieniec Formation is from Szczepanik and Żylińska (2012). The trilobite faunas from the Ociesęki and Kamieniec formations discussed herein are marked as 1 and 2, respectively in northern Germany is considered to correspond to the upper part of the traditional Holmia kjerulfi-group Zone of Sweden .…”
