The origin of the animals and a 'Savannah'hypothesis for early bilaterian evolution
The earliest evolution of the animals remains a taxing biological problem, as all extant
clades are highly derived and the fossil record is not usually considered to be helpful. The …

The end of the Ediacara biota: Extinction, biotic replacement, or Cheshire Cat?
The Ediacaran–Cambrian transition signals a drastic change in both diversity and
ecosystem construction. The Ediacara biota (consisting of various metazoan stem lineages …

The rise of animals in a changing environment: global ecological innovation in the late Ediacaran
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 …

Giving the early fossil record of sponges a squeeze
Twenty candidate fossils with claim to be the oldest representative of the P hylum P orifera
have been re‐analysed. Three criteria are used to assess each candidate:(i) the diagnostic …

The advent of animals: the view from the Ediacaran
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 …

Soft‐bodied fossils are not simply rotten carcasses–toward a holistic understanding of exceptional fossil preservation: exceptional fossil preservation is complex and …
Exceptionally preserved fossils are the product of complex interplays of biological and
geological processes including burial, autolysis and microbial decay, authigenic …

[HTML][HTML] Remarkable insights into the paleoecology of the Avalonian Ediacaran macrobiota
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 …

Ediacaran distributions in space and time: testing assemblage concepts of earliest macroscopic body 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 …

Ediacaran biozones identified with network analysis provide evidence for pulsed extinctions of early complex life
Abstract Rocks of Ediacaran age (~ 635–541 Ma) contain the oldest fossils of large, complex
organisms and their behaviors. These fossils document developmental and ecological …

Haootia quadriformis n. gen., n. sp., interpreted as a muscular cnidarian impression from the Late Ediacaran period (approx. 560 Ma)
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 …
