Following the logic behind biological interpretations of the Ediacaran biotas

Abstract For almost 150 years, megascopic structures in siliciclastic sequences of terminal Precambrian age have been frustratingly difficult to characterize and classify. As with all other areas of

Of time and taphonomy: preservation in the Ediacaran

The late Neoproterozoic witnessed a revolution in the history of life: the transition from a microbial world to the one known today and this Period is also recognized for its abundance of soft-tissue preservation, which is viewed through a wide variety of taphonomic windows.

The origin of the animals and a ‘Savannah’ hypothesis for early bilaterian evolution

The subtle remnants of Ediacara‐style taxa within the Cambrian suggest that they remained significant components of Phanerozoic communities, even though at some point their enabling role for bilaterian evolution was presumably taken over by bilaterians or other metazoans.

Discs and discord: The paleontological record of Ediacaran discoidal structures in the south American continent

Ecological Expansion and Extinction in the Late Ediacaran: Weighing the Evidence for Environmental and Biotic Drivers.

The Ediacara Biota, Earth's earliest communities of complex, macroscopic, multicellular organisms, appeared during the late Ediacaran Period, just prior to the Cambrian Explosion, and is likely to have been part of an ecological and evolutionary continuum.

Resolution of the earliest metazoan record: Differential taphonomy of Ediacaran and Paleozoic fossil molds and casts

Disc-shaped fossils resembling porpitids or eldonids from the early Cambrian (Series 2: Stage 4) of western USA

The morphology and affinities of newly discovered disc-shaped, soft-bodied fossils from the early Cambrian (Series 2: Stage 4, Dyeran) Carrara Formation are discussed and their status as biologic structures and thus actual fossils is supported.

Lifestyle of the Octoradiate Eoandromeda in the Ediacaran

Abstract. The octoradiate Eoandromeda Tang et al. from the Ediacaran of South China and South Australia is poorly understood and there are different interpretations of its morphology and

Remarkable insights into the paleoecology of the Avalonian Ediacaran macrobiota

Reassessment of the Devonian problematicum Protonympha as another post‐Ediacaran vendobiont

Protonympha is an enigmatic fossil represented by two species from the Middle Devonian (Protonympha transversa) and Late Devonian (Protonympha salicifolia) of New York. Although interpreted in the

Ediacaran lichens: a critique

Retallack (1992,1994) has proposed that the late Precambrian (Vendian) "Ediacara organ­ isms' were as tough and resistant to compac­ tion as tree trunks. Contradicting traditional views of the

Ediacaria booleyi: weeded from the Garden of Ediacara?

Abstract Sole markings from the Upper Cambrian Booley Bay Formation at Booley Bay, Co. Wexford, Ireland, previously described as the Ediacaran-type fossil Ediacaria booleyi appear to possess a number

A Fungal Analog for Newfoundland Ediacaran Fossils?1

It is proposed that some of the more conspicuous Ediacaran fossils from the Avalon Peninsula of Newfoundland, including Aspidella, Charnia, and Charniodiscus, were biologically similar to members of the Kingdom Fungi, yet reflect characteristics of modern fungal mycelia.

THE EDIACARA BIOTA: Neoproterozoic Origin of Animals and Their Ecosystems

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.

Discoidal fossils of the Ediacaran biota: a review of current understanding

Abstract Discoidal fossils, despite being the oldest, youngest, and most common elements of the Ediacaran biota, have not received their fair share of attention. Taxonomy of discoidal fossils is

Ediacaran fossils are taphonomically similar to impressions of fossil plants common in quartz sandstones, and the relief of the fossils suggests that they were as resistant to compaction during

Abstract Functional, constructional, and preservational criteria led to a reinterpretation of seemingly complex trace fossils and the majority of assumed metazoan body fossils from Vendian

Fossil assemblages that preserve soft-bodied organisms are essential for our understanding of the composition and diversity of past life. The worldwide terminal Proterozoic Ediacara-type fossils

A biota of Ediacaran aspect from lower Cambrian strata on the Digermul Peninsula, Arctic Norway

Three elements of the ‘Ediacara fauna’ are described from lower Cambrian strata on the Digermul Peninsula, Norway. Nimbia occlusa Fedonkin, 1980 and Tirasiana sp. occur approximately 80 m above the
