The non-availability of biomineralized skeletons and low levels of predation led Vendian evolution along strange avenues. The Ediacara-type Vendobionta appear to represent a kingdom, in which foliate shapes, large sizes and the necessary compartmentalization were achieved by quilting of the skin rather than by multicellularity. Psammocorallia, in contrast, are interpreted as coelenterates that constructed an internal sand skeleton. Both were immobile soft-bottom dwellers that had high…

The nature of vendobionts

Abstract The notion that the majority of Ediacaran fossils do not represent stem groups to modern metazoan phyla is now increasingly accepted. Nevertheless, the further claim of the vendobiont

Underground Vendobionta From Namibia

The late Precambrian fossils from Namibia have generally been regarded as soft‐bodied organisms whose three‐dimensional preservation resulted from smothering in fluidized sand. The sedimentological

Biomat-related lifestyles in the Precambrian

The strange biota of Neoproterozoic sea bottoms become more understandable if we assume that otherwise soft sediments were sealed by firm and erosion-resistant biomats. This allowed "mat encrusters"

Lower Cambrian Vendobionts from China and Early Diploblast Evolution

A frondlike fossil, Stromatoveris, is described from the Lower Cambrian Chengjiang Lagerstätte (Yunnan, China) that is strikingly similar to Ediacaran vendobionts and has important implications for the early evolution of this phylum and related diploblasts, some of which independently evolved a frondose habit.

Competition in a Precambrian world: palaeoecology of Ediacaran fronds

It is believed that the frond shape most likely represents a common need to elevate a feeding apparatus higher in the water-column to feed from the upper (> 20 cm) tiers, and represents a shared ecology, not ancestry.

Symmetry of Vendobionta (Late Precambrian Metazoa)

Vendobionta is a large group of Precambrian Metazoa, which is characterized by a set of symmetry elements arranged in a certain system of mutual subordination and typically not found in unitary

Spindle-shaped Ediacara fossils from the Mistaken Point assemblage, Avalon Zone, Newfoundland

The Mistaken Point assemblage of the Ediacara fossils is dominated by rangeomorphs with homologous fractal branching elements. The most distinctive are the fusiform fossils, herein named Fractofusus

Modular Construction of Early Ediacaran Complex Life Forms

Newly discovered, exceptionally preserved, soft-bodied fossils near Spaniard's Bay in eastern Newfoundland exhibit features not previously described from Ediacaran (terminal Neoproterozoic) fossils.

The Ediacarian Period and Syste: Metazoa Inherit the Earth

The Ediacarian, here defined as the initial period and system of the Phanerozoic Eon, is characterized by the oldest known multicellular animal life, represented in the type region by 26 species in 18 genera and 4 or more phyla, plus simple metazoan surface tracks.

Abstract Umbrella‐shaped objects, presumably fossils, were collected from the Lower Proterozoic Noltenius Formation at two localities about 80 miles south of Darwin. Radial and concentric forms are

Oxygen requirements, biology and phylogenetic significance of the late Precambrian worm Dickinsonia, and the evolution of the burrowing habit

Dickinsonia was a very thin subcircular to elliptical worm that grew to about a metre in length and was probably an annelid, but may have been neither a polychaete nor an oligochaete, and its geometry and ontogeny suggest that its similarity to the living discoidalpolychaete Spinther is due to convergence.
