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 …

The origin of motility in bilaterian animals represents an evolutionary innovation that
transformed the Earth system. This innovation probably occurred in the late Ediacaran …

Analysis of modern animals and Ediacaran trace fossils predicts that the oldest bilaterians
were simple and small. Such organisms would be difficult to recognize in the fossil record …

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 …

Accumulated records of organic microfossils span billions of years of Earth history. The
majority of this record consists of prokaryotes plus eukaryotes of a protistan grade, yet this …

The oldest animals appear in the fossil record among Ediacara biota communities. They
prelude animal-dominated ecosystems of the Phanerozoic and may hold clues to the …

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 Conception and St. John's Groups of southeastern Newfoundland contain
some of the oldest known fossils of the Ediacaran macrobiota. The Mistaken Point …

The discovery of Dickinsonia in India allows assessment of biogeographic provinces and
plate tectonic reconstructions for the late Ediacaran. The fossils were found in the roof of …
