Molecular timescales estimate that early animal lineages diverged tens of millions of years
before their earliest unequivocal fossil evidence. The Ediacaran macrobiota (~ 574 to 538 …

The driving forces behind the evolution of early metazoans are not well understood, but key
insights into their ecology and evolution can be gained through ecological analyses of the in …

ABSTRACT Rocks of the Ediacaran System (635–541 Ma) preserve fossil evidence of some
of the earliest complex macroscopic organisms, many of which have been interpreted as …

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 …

The Ediacara Biota represents the oldest fossil evidence for the appearance of animals but
linking these taxa to specific clades has proved challenging. Dickinsonia is an abundant …

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 …

Ediacaran fronds are key components of terminal-Proterozoic ecosystems. They represent
one of the most widespread and common body forms ranging across all major Ediacaran …

Ediacaran rangeomorphs were the first substantially macroscopic organisms to appear in
the fossil record, but their underlying biology remains problematic. Although demonstrably …

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 …

Ediacara fossils document an important evolutionary episode just before the Cambrian
explosion and hold critical information about the early evolution of macroscopic and …
