Platysolenites, other animal fossils, and the Precambrian-Cambrian transition in Norway

The late Precambrian and L. Cambrian autochthonous sedimentary sequences in N. Norway and adjoining areas and their fossils are reconsidered, and the available specimens are re-described. One L. Cambrian foraminiferal fossil (Spirosolenites spiralis) and one Late Precambrian medusoid coelenterate (Kullingia concentrica) are named as new genera and species. The thickness changes and breaks in sedimentation in the platform cover compared with the 'miogeosynclinal' Digermul section are demonstrated.
