Bacteria play an important role in the fossilization of soft tissues; their metabolic activities
drive the destruction of the tissues and also strongly influence mineralization. Some …

Over 3.7 billion years of Earth history, life has evolved complex adaptations to help navigate
and interact with the fluid environment. Consequently, fluid dynamics has become a …

The fossil record of the terminal Ediacaran Period is typified by the iconic index fossil
Cloudina and its relatives. These tube-dwellers are presumed to be primitive metazoans, but …

Earth's earliest fossils of complex macroscopic life are recorded in Ediacaran-aged
siliciclastic deposits as exceptionally well-preserved three-dimensional casts and molds …

Abstract The Ediacaran–Cambrian boundary strata in the Great Basin of the southwestern
United States record biological, geochemical, and tectonic change during the transformative …

The soft-bodied Ediacara biota (571–541 million years ago) represents the oldest complex
large organisms in the fossil record, providing a bridge between largely microbial …

Microbially mediated early diagenetic pyrite formation in the immediate vicinity of organic
material has been the favored mechanism by which to explain widespread preservation of …

Abstract Fossils of the Ediacara Biota preserve the oldest evidence for complex,
macroscopic animals. Most are difficult to constrain phylogenetically, however, the presence …

The earliest evidence of complex macroscopic life on Earth is preserved in Ediacaran‐aged
siliciclastic deposits as three‐dimensional casts and molds, known as Ediacara‐style …

A long-running debate over the affinities of the Neoproterozoic 'Ediacara biota'has led to
contrasting interpretations of Ediacaran ecosystem complexity. A 'simple'model assumes …
