The evolutionary trajectory of early complex life on Earth is interpreted largely from the
fossils of the Precambrian soft-bodied Ediacara Biota, which appeared and evolved during a …

Ediacaran macrofossils from the Avalon Terrane (primarily eastern Newfoundland and the
central UK) record some of the earliest large and complex multicellular organisms on Earth …

Patterns of origination and evolution of early complex life on this planet are largely
interpreted from the fossils of the Precambrian soft-bodied Ediacara Biota. These fossils …

The mid-late Ediacaran Period (~ 579–541 Ma) is characterized by globally distributed
marine soft-bodied organisms of unclear phylogenetic affinities colloquially called the …

Mobility represents a key innovation in the evolution of complex animal life. The ability to
move allows for the exploration of new food sources, escapes from unfavorable …

Muscle tissue is a fundamentally eumetazoan attribute. The oldest evidence for fossilized
muscular tissue before the Early Cambrian has hitherto remained moot, being reliant upon …

Impressions of soft-bodied Ediacaran megafossils are common in deep-water slope
deposits of the June beds at Sekwi Brook in the Mackenzie Mountains of NW Canada. Two …

Abstract The Ediacara Member of the Rawnsley Quartzite of South Australia hosts some of
the most ecologically and taxonomically diverse fossil assemblages of the eponymous …

It has been proposed that the terminal Neoproterozoic Ediacara biota were driven to
extinction by the evolution of metazoan groups capable of engineering their environments …

The radiation of early animals involved dramatic turnover of both eukaryotic life and marine
environments, but the factors that drove origination and extinction of taxa remain …
