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

The Skyberg Lagerstätte from the Mjøsa area, Norway: a rare window into the late early Cambrian biodiversityof Scandinavia

“…The free cheeks possess a broad-based, posteriorly placed short spine (occurring on PMO 249.323, not figured). The species is very similar to the supposed slightly older E. anartanus Geyer et al, 2004, and is previously unknown from Norway.…”

“…Kiaer (1917) figured Ellipsocephalus Nordenskjöldi from the Mjøsa area, but were later reassigned to Ellipsocephalus gripi (Ahlberg & Bergström 1978;Høyberget et al 2015), now Ellipsostrenua gripi (Kautsky, 1945). Geyer et al (2004) erected the ellipsocephalid genus Epichalnipsus based on ice-rafted material presumably deriving from early Cambrian strata in southern Sweden. Several species from the Skyberg Member may be assigned to this genus, which is characterized by a tapering glabella with a slightly acute anterior lobe and the frontal area distinctly separated from the glabella.…”

“…Strenuella primaeva var. rotundata was established by Kiaer (1917) and later assigned to Proampyx (Ahlberg & Bergström 1978), tentatively to Berabichia (Geyer et al 2004;Weidner et al 2015) and currently to Epichalnipsus (Cederström et al 2022). Kiaer (1917) based the description on a specimen from Forsemölla in eastern Skåne, and the species is previously not recorded from Norway.…”
