It was a serious mistake when subdivision stratotypes had been disposed of in practice of constructing the General stratigraphic scale, because they cannot be substituted by the boundary stratotypes. A subdivision stratotype and respective GSSP are complementary parts characterizing any stratigraphic unit. The best candidates for stage stratotypes of the Lower Cambrian are certainly sections of the Lena-Aldan region in the Siberian platform, which have been studied in detail during many years…

New data on biostratigraphy of the Vendian Nemakit-Daldynian stage in the southern Siberian platform

Watsonella crosbyi from the lower Cambrian (Terreneuvian, Stage 2) Normanville Group in South Australia
Abstract Correlation of lower Cambrian strata is often confounded by provincialism of key fauna. The widespread occurrence of the micromollusc Watsonella crosbyi Grabau, 1900 is therefore an…

Correlation of the Cambrian Evolutionary Radiation: geochronology, evolutionary stasis of earliest Cambrian (Terreneuvian) small shelly fossil (SSF) taxa, and chronostratigraphic significance
Abstract Early faunas with Watsonella crosbyi with or without Aldanella spp. have been equated with the Siberian Tommotian Stage (uppermost Terreneuvian) and used to define a proposed Cambrian Stage…
Quo vadis, Tommotian?
Abstract The concept of the Tommotian Regional Stage of the Siberian Platform has been closely linked to the idea of the ‘Cambrian Explosion’ of animals and protists when the entire Earth system…
Integrated stratigraphic, geochemical, and paleontological late Ediacaran to early Cambrian records from southwestern Mongolia
In their comment, Landing and Kruse disagree with some of our discussion and, at times, use blanket statements to incorrectly summarize from the Smith et al. (2016) paper. This is not the venue for a…

The stage scale of the Cambrian System
Abstract A stage subdivision of the Cambrian System is proposed. In the lower series four stages are distinguished (the Tommotian, Atdabanian, Botomian, Tojohnian); in the middle series, two (the…

Changing perspectives on Cambrian chronostratigraphy and progress toward subdivision of the Cambrian system
Important steps have been made toward global subdivision of the Cambrian System. The consensus of opinion is that the system should be subdivided into four series representing subequal spans of time.…
