Organisms and the manner in which they fit into early animal evo- lution is offered by examination of the paleoecology, morphology, and taphonomy of fossils of the ediacara biota. Characteristics of the ediacaran biota there are currently around 200 species of macro-organisms that have been described from the ediacaran period, an interval of time 635-541 million years ago that was only formally erected in 2004 (knoll et al 2004) the earliest macro-organisms only appear in the late ediacaran period, ~575 million years ago, with specimens from newfoundland currently thought to be amongst the oldest.

The ediacaran is dated between 635 and 540 million years ago it preceded the cambrian period, about 540 to 485 million years ago, which marked the beginning of one of the biggest explosions of life in the history of earth for a long time, scientists thought the cambrian period was when multicellular life first ran rampant. Although many of the ediacaran organisms have been compared to modern-day jellyfish or worms, they have also been described as resembling a mattress, with tough outer walls around fluid-filled internal cavities - rather like a sponge. The history of animal evolution for many people animals are perhaps the most familiar, and most interesting, of living things as such, we have a number of features in common with all the organisms placed in the animal kingdom, and these common features indicate that we have a shared evolutionary history although many of the ediacaran.

The advent of animals: the view from the ediacaran mary l drosera,1 and james g gehlingb,c fossils of these multicellular organisms demonstrate the advent of mobility , heterotrophy by multicellular animals, skeletonization, sexual reproduction, and the assembly of one of the defining characteristics of the ediacara biota fossils is.
Some ediacaran strata with the texture characteristics of microbial mats contain fossils, and ediacaran fossils are almost always found in beds that contain these microbial mats although microbial mats were once widespread, the evolution of grazing organisms in the cambrian vastly reduced their numbers.
