Correlating the Ediacaran of Australia

Geological Society, London, Special Publications, 2007
Abstract Now that a Global Stratotype Section and Point (GSSP) has been ratified and a new system defined for the terminal Proterozoic era, the Ediacaran, the next step is to develop global correlations and to further subdivide this system. Means of correlating and subdividing older parts of the Proterozoic era are also needed.

Ediacaran epifaunal tiering

Geology, 2002
Epifaunal tiering, the subdivision of vertical space within a community, is a fundamental attribute of Phanerozoic suspension-feeding communities. This paper documents tiering, including the presence of meter-tall organisms, in Neoproterozoic Ediacaran communities.

Ediacaran microbial colonies

Lethaia, 2007
Enigmatic discoidal fossils are common in Neoproterozoic sedimentary sequences and in the stratigraphic record pre-date the first appearance of diverse Ediacaran fossil assemblages. Termed ‘medusoids’, these Neoproterozoic discoidal fossils have generally been interpreted as coelenterate-grade organisms implying a radially symmetrical body plan for ...

Ediacaran holdfasts and their systematics

Journal of Earth Science, 2010
INTRODUCTION Fossil holdfasts of soft-bodied organisms are widespread in Ediacaran (Vendian) deposits, although they have long been interpreted as casts of jelly-fish (Glaessner and Wade, 1966; Sprigg, 1949) or modes of preservation of other organisms. The fact that microbial colonies (Grazhdankin and Gerdes, 2007) and sedimentary structures (Jensen et

The Ediacaran Fossils

Abstract Below the base of the Cambrian lies the Ediacaran period. Unexpectedly, a diverse biota of large fossils has been found at several sites around the world. It is especially well represented at the classical locality in South Australia, where upright fronds, prostrate leaf-shaped organisms with an odd kind of segmentation, and ...

The Ediacaran Thread

Abstract The meiofauna scenario does not define the sequence of body plans leading to modern animals. This chapter suggests a sequence of viable body plans, demonstrated whenever possible by fossils or relics, and linked by plausible transitions that offer some immediate benefit.

The Calibration of Ediacaran Time

Science, 2005
During the Ediacaran Period, Earth9s earliest soft-bodied organisms emerged in the oceans. In his Perspective, Kaufman highlights the report by Condon et al ., who have analyzed two layers from the Doushantuo Formation of southern China.
