A kinetic model of Phanerozoic taxonomic diversity I. Analysis of marine orders
TL;DR: This model appears to describe adequately the “explosive” diversification of known metazoan orders across the Precambrian-Cambrian Boundary, suggesting that no special event, other than the initial appearance of Metazoa, is necessary to explain this phenomenon.

A kinetic model of Phanerozoic taxonomic diversity II. Early Phanerozoic families and multiple equilibria
TL;DR: In this paper, a two-phase kinetic model of taxonomic diversity was proposed to describe the early success of ecologically generalized taxa and their later replacement by more specialized taxa.

Morphological disparity in Ordovician-Devonian crinoids and the early saturation of morphological space
TL;DR: Comparison with generic richness reveals that the full range of form was essentially attained by the early part of the Caradocian, long before the time of maximal taxonomic diversity.

TL;DR: In this article, the first appearances of major animal groups with mineralized skeletons on the Siberian Platform and worldwide are revised and summarized with references to an improved carbon isotope stratigraphy and radiometric dating in order to reconstruct the Cambrian radiation with a higher precision and provide a basis for the definition of Cambrian Stages 2 to 4.
