Abstract The Ediacaran-Cambrian transition, which incorporates the radiation of animals,
lacks a robust global temporal and spatial framework, resulting in major uncertainty in the …

The trace-fossil record provides a wealth of information to track the rise and early evolution
of animals. It comprises the activity of both hard-and soft-bodied organisms, is continuous …

Cnidarians are a disparate and ancient phylum, encompassing corals and jellyfish, and
occupy both the pelagic and benthic realms. They have a rich fossil record from the …

Biogenic signatures in Precambrian rocks are often difficult to confirm and debatable. We
present some unusual features associated with microbial-mat related structures (MRS) from …

Abstract The Crato Konservat-Lagerstätte is one of the main Mesozoic fossil sites from
Gondwana, recording a wide diversity of terrestrial and non-marine aquatic fossils of great …

Simple and horizontal trace fossils from the Ediacaran Period (635–538.8 Ma) compose
some of the oldest evidence for the presence of metazoans in the Proterozoic fossil record …

Various evaluations of the last common bilaterian ancestor (lcba) currently suggest that it
resembled either a microscopic, non-segmented motile adult; or, on the contrary, a complex …

Microbially induced sedimentary structures (MISS) are abundant in Ediacaran and lower
Cambrian successions. However, the relationship between MISS distribution and facies has …
