Abstract:  The fossil record documents two mutually exclusive macroevolutionary modes separated by the transitional Ediacaran Period. Despite the early appearance of crown eukaryotes and an at least partially oxygenated atmosphere, the pre‐Ediacaran biosphere was populated almost exclusively by microscopic organisms exhibiting low diversity, no biogeographical partitioning and profound morphological/evolutionary stasis. By contrast, the post‐Ediacaran biosphere is characterized by large diverse… 
Macroevolutionary turnover through the Ediacaran transition: ecological and biogeochemical implications
TLDR
Intermittent return to the pre-Ediacaran state during Phanerozoic extinctions and oceanic anoxic events suggests that the widespread anoxia detected in pre- Ediacaran deep-marine sequences may be a consequence of this alternate biological pump rather than a reflection of fundamentally lower levels of atmospheric oxygen.
Morphodiversity, complexity and macroevolution: revealed by the megascopic life of the Palaeo-Neoproterozoic Vindhyan Supergroup, India
Abstract Evidence of past life found in the Vindhyan Supergroup exhibits extensive diversity and taxonomically unresolved morphological complexities indicating varied biological affinities, advanced
The Ediacaran emergence of bilaterians: congruence between the genetic and the geological fossil records
TLDR
The two historical records of life both suggest that although the cradle of Metazoa lies in the Cryogenian, and despite the explosion of ecology that occurs in the Cambrian, it is the emergence of bilaterian taxa in the Ediacaran that sets the tempo and mode of macroevolution for the remainder of geological time.
Global species richness record and biostratigraphic potential of early to middle Neoproterozoic eukaryote fossils
Late Ediacaran redox stability and metazoan evolution
SCALE AND HIERARCHY IN MACROEVOLUTION
TLDR
Scale and hierarchy must be incorporated into any conceptual framework for the study of macroevolution, i.e. evolution above the species level, as well as complex hierarchical effects that remain poorly understood.
Dynamic redox conditions control late Ediacaran metazoan ecosystems in the Nama Group, Namibia
The first appearance of skeletal metazoans in the late Ediacaran (∼550 million years ago; Ma) has been linked to the widespread development of oxygenated oceanic conditions, but a precise spatial and
The 2.1 Ga Old Francevillian Biota: Biogenicity, Taphonomy and Biodiversity
TLDR
Combined microtomography, geochemistry, and sedimentary analysis suggest a biota fossilized during early diagenesis follows a rise in atmospheric oxygen, consistent with the idea that surface oxygenation allowed the evolution and ecological expansion of complex megascopic life.
Evolutionary Trends in Remarkable Fossil Preservation Across the Ediacaran–Cambrian Transition and the Impact of Metazoan Mixing
A unifying model is presented that explains most of the major changes seen in fossil preservation and redox conditions across the Precambrian–Cambrian transition. It is proposed that the quality of

Macroevolution is more than repeated rounds of microevolution

TLDR
The attractiveness of macroevolution reflects the exhaustive documentation of large‐scale patterns which reveal a richness to evolution unexplained by microevolution, and studies from paleontology, phylogenetics, developmental biology, and other fields demand the deeper view provided by Macroevolution.
Disparate rates, differing fates: tempo and mode of evolution changed from the Precambrian to the Phanerozoic

TLDR
In both tempo and mode of evolution, much of the Precambrian history of life--that dominated by microscopic cyanobacteria and related prokaryotes--appears to have differed markedly from the more recent Phanerozoic evolution megascopic, horotelic, adaptationally specialized eukaryotes.

Plankton ecology and the Proterozoic-Phanerozoic transition
TLDR
The major biogeochemical perturbations that mark the onset of the Phanerozoic might be a consequence, rather than a cause, of the Cambrian explosion; reduced C export due to zooplankton expansion explains the otherwise anomalous drop in 813C at the base of the Tom- motian.
Biodiversity, speciation, and extinction trends of Proterozoic and Cambrian phytoplankton
The degradation-resistant organic-walled cell envelopes of acritarchs are the most abundant microfossils in Proterozoic and Cambrian rocks. These microfossils reveal diversity fluctuations that

TLDR
This work compares the rates of expansion and truncation of preserved marine sedimentary basins to rates of origination and extinction among Phanerozoic marine animal genera and suggests that the processes responsible for producing variability in the sedimentary rock record, such as plate tectonics and sea-level change, may have been dominant and consistent macroevolutionary forces throughout the Phanrozoic.
THE EDIACARA BIOTA: Neoproterozoic Origin of Animals and Their Ecosystems
TLDR
Present evidence suggests that the Ediacara biota included a mixture of stem- and crown-group radial animals, stem-group bilaterian animals, “failed experiments” in animal evolution, and perhaps representatives of other eukaryotic kingdoms.
Eukaryotic organisms in Proterozoic oceans
TLDR
Focus on character evolution permits inferences about the innovations in cell biology and development that underpin the taxonomic and morphological diversification of eukaryotic organisms.
