Horodyskia is one of the earliest known macroscopic life forms, with a fossil record dating from c. 1.4 Ga. Palaeopascichnus represents a key Ediacaran element with world-wide distribution. However, their body constructions and affinities are poorly understood, partly because previously described species are mostly preserved as casts and moulds in siliciclastic rocks. Silicified specimens from the upper Ediacaran Liuchapo Formation in eastern Guizhou, South China, are described as Horodyskia… Expand

Ediacaran Acanthomorphic Acritarchs and Other Microfossils From Chert Nodules of the Upper Doushantuo Formation In the Yangtze Gorges Area, South China
Abstract Silicified microfossils preserved in chert nodules of the Doushantuo Formation in the Yangtze Gorges area of South China have great potential to improve the biostratigraphic subdivision and… Expand
Micropaleontology of the lower Mesoproterozoic Roper Group, Australia, and implications for early eukaryotic evolution
TLDR
Roper fossils provide direct or inferential evidence for many basic features of eukaryotic biology, including a dynamic cytoskeleton and membrane system that enabled cells to change shape, life cycles that include resting cysts coated by decay-resistant biopolymers, reproduction by budding and binary division, osmotrophy, and simple multicellularity.

A new modular palaeopascichnid fossil Curviacus ediacaranus new genus and species from the Ediacaran Dengying Formation in the Yangtze Gorges area of South China
Abstract Non-biomineralizing Ediacaran macrofossils are rare in carbonate facies, but they offer valuable information about their three-dimensional internal anatomy and can broaden our view about… Expand
Orbisiana linearis from the early Ediacaran Lantian Formation of South China and its taphonomic and ecological implications
Abstract Orbisiana is an Ediacaran fossil characterized by linearly arranged circular or cylindrical units. The genus was first described from the late Ediacaran Redkino Series in the Moscow Syncline… Expand

Possible animal body fossils from the Late Neoproterozoic interglacial successions in the Kimberley region, northwestern Australia
Abstract New specimens of the enigmatic Ediacara-type fossil Palaeopascichnus have been identified from the upper part of the Neoproterozoic Ranford Formation in the Kimberley region, northwest… Expand
Horodyskia williamsii new species, a Mesoproterozoic macrofossil from Western Australia
Abstract A new species of abundant macrofossil, previously described informally as a ‘string of beads’, is here assigned to the genus Horodyskia Yochelson and Fedonkin, 2000, and formally named… Expand
A Horodyskia-Nenoxites-dominated fossil assemblage from the Ediacaran-Cambrian transition (Liuchapo Formation, Hunan Province): Its paleontological implications and stratigraphic potential
Abstract Because of the scarcity of fossil data, life evolution in deep-water settings through the Ediacaran-Cambrian transitional interval is still poorly understood. This study describes a… Expand
Testing the protozoan hypothesis for Ediacaran fossils: a developmental analysis of Palaeopascichnus
TLDR
Developmental analysis of the Palaeopascichnus reveals unusual, protozoan features, including evidence for chaotic repair structures, for mergence of coeval forms, as well as complex bifurcations, which suggest that Palaeobiology is a body fossil of an unidentified protozoa but is unrepresentative of Ediacaran body construction, in general.

The oldest record of Ediacaran macrofossils in Gondwana (~563 Ma, Itajaí Basin, Brazil)
Abstract The Avalon biota (Ediacaran Period, 570–559 Ma) marks the first appearance of macroscopic and complex benthic communities in the fossil record. This assemblage is known from a few localities… Expand

A uniquely preserved Ediacaran fossil with direct evidence for a quilted bodyplan.
TLDR
An Ediacara form, uniquely preserved in situ and in three dimensions with its organic walls cast by early diagenetic calcite, from bituminous limestone of the 551- to 542-mega-annum Dengying Formation of South China is reported, which probably lived procumbently at or near the water-sediment interface and shows evidence for substrate utilization.
