Some problems concerning the Precambrian-Cambrian transition and the Cambrian faunal radiation
Article Abstract:
An analysis describing research which have an impact on the Precambrian-Cambrian transition and the latter period's faunal radiation is presented. Descriptions of the 'pre-Tommotian' age present misunderstanding concerning facies control over faunal distribution. Analysis of evolutionary patterns indicate the development of archaeocyathan morphology on the Siberian Platform prior to the Tommotian period. These phenomena provide a basis for basinal variations related to the Palaeopangea breakup.

Patterns of phytoplankton radiation across the Precambrian-Cambrian boundary
Article Abstract:
A study was conducted to examine phytoplankton patterns during the Precambrian-Cambrian transition. During that stage, phytoplankton was composed of a vast range of microfossils which exhibited bacterial and algal affinity. Proterozoic-Cambrian radiation patterns were extended to sequences in the East European and Siberian Platforms, Chian, Baltoscandia and North America. Results show that these radiation patterns provide basis for explaining biotic events around the studied period.
