It has long been assumed that the extant bilaterian phyla generally have their origin in the
Cambrian explosion, when they appear in an essentially modern form. Both these …

Abstract Permian–Triassic boundary microbialites (PTBMs) are thin (0.05–15 m) carbonates
formed after the end‐Permian mass extinction. They comprise Renalcis‐group …

Taphonomy plays diverse roles in paleobiology. These include assessing sample quality
relevant to ecologic, biogeographic, and evolutionary questions, diagnosing the roles of …

All possible combinations of six tiering positions in relation to the substratum/water interface,
six motility levels and six feeding strategies define a complete theoretical ecospace of 216 …

The biomass of marine consumers increased during the Phanerozoic. This is indicated by
the increase in both fleshiness and average size of individuals of dominant organisms …

Paleoecologic study of invertebrate faunas from three successive Early Triassic seaways
reveals that biotic recovery from the end-Permian mass extinction event was slow, and that …

The end-Permian mass extinction greatly affected the sedimentary record, but the
sedimentary response was not limited to the Permian–Triassic boundary interval. This …

Palaeo-water depth and its change with time is a key factor in environmental analysis and in
sedimentology in general. The literature published on this topic and on related subjects …

Bioturbation, the physical and chemical mixing of sediment by burrowing animals, exerts an
important control on the character of modern marine sediments and biogeochemical …

The end-Permian mass extinction greatly diminished marine diversity and brought about a
whole-scale restructuring of marine ecosystems; these ecosystem changes also profoundly …
