Topic: Ediacara


  
  The Cambrian explosion - The Ediacara   (Site not responding. Last check: 2007-10-16)
One group see at least some of the Ediacara as members of known phyla and therefore potential ancestors of the lower Cambrian metazoans, for example the Ediacaran frond-like fossils are possible cnidarians, and some of the bilaterally symmetrical segmented organisms could be ancestral to the annelids and arthropods.
The opposing view is that the Ediacara are not on the main evolutionary line to later metazoans, they represent rather a 'failed experiment' in multicellular design, and perhaps are not really animals at all (references Buss & Seilacher.
If the Ediacara are unique and unlike any biota alive since, it is possible their body walls were contructed from a substance tougher than conventional soft-bodied organisms, and therefore with greater fossilization potential.

 Ediacara Hills, Australia
Appropriately, the name "Ediacara" comes from an Aboriginal language expression meaning "veinlike spring of water" — the "spring," perhaps, from which complex animals have arisen.
Fossils from the Ediacara Hills: On the left is Arkarua, a small disc-shaped animal that may be the oldest echinoderm.
Specimens collected from the Ediacara Hills are almost all housed in the South Australian Museum.

 Ediacaran Fossils of Canada
Before this discovery, it was believed either that animals had not evolved during the Precambrian, or that they could not be fossilized since they did not have hard skeletons or shells.
Recent fossils found in Namibia show us that members of the Ediacara Biota did populate the oceans up until the end of the Precambrian (545 million years ago).
These worms, and some other members of the Ediacara Biota, survived the extinction event and took part in the greatest evolutionary event in Earth's history: The Cambrian "Explosion" of Life.

 The Ediacaran Assemblage
Interestingly, it appears that Ediacaran communities were largely free of large predators; no species appears to have possessed a jaw apparatus suitable for seizing and tearing prey, and few fossils show clear evidence of predatory damage.
A trace fossil presumed to represent the radula scratches of a mollusc is found at Zimnie Gory and in the Ediacara Hills (Martin et al.
Mark McMenamin (1986, 1998) coined the phrase ‘garden of Ediacara’ to encapsulate the concept and he has largely championed this theory.

 Fact sheet for Australia Before Time: Ediacara Fauna Fossils
Today Australia is a hot, dry continent but hundreds of millions of years ago the landscape was very different.
Before Sprigg's discovery - at a time when only fossils of hard-shelled organisms from later time periods were well-known - scientists believed it was impossible for soft-bodied organisms, from the earliest stages of development of life on earth, to be preserved in ancient rocks.
The fossils found at Ediacara disproved this theory.

 Ediacara   (Site not responding. Last check: 2007-10-16)
When the Ediacara field was subjected to a closer examination it was not long before the miners realised that this silver-lead mineral was widely spread.
The Ediacara Silver Mining Company Ltd., formed in May 1888, was a syndicate of 640 shares of $200 each.
They argued that: with the Sliding Rock to the east, the Ediacara and others to the south, and the numerous copper mines all round the district, smelters should pay handsomely, besides helping to develop the mineral resources of the north and give employment to hundreds of men.
