Answer :
The Ediacaran features fossils that are supposed to show the earliest animal movement, biomineralization, predation, and reefs, among other significant evolutionary breakthroughs. The Ediacaran biota, on the other hand, are perhaps the most notorious Ediacaran fossils. Major findings on the beginnings of the animal groups are being produced further back in time, in the Ediacaran period.
The Ediacaran Period spans the time between the termination of the Marinoan Glacier and the emergence of rather complex trace fossils globally (Treptichnus pedum). The Ediacaran Period is unique in comparison to succeeding periods since its beginning is not indicated by a change in the fossil record, despite the presence of soft-bodied fossils in this period. The beginning is really established at the base of a layer of chemically different carbonate, sometimes known as a "cap carbonate," so named because it crowns glacial deposits.
It is challenging to resolve their core biology, such as their phylogenetic relationships or their ecology, because these Ediacaran species are essentially different from those discovered at other times. Together with the Cambrian fossil record, the Ediacaran era is revealed as a period of unmatched biological innovation and diversification in the history of the planet. Ediacaran fossils unquestionably document significant advances in eukaryotic evolution.
Although many Ediacaran forms' specific identities are still unknown, our knowledge of both individual animals and larger ecosystems is advancing at a remarkable rate. Every year, new and fascinating fossils are found, and many more have not yet been fully described and researched. Our best chance of understanding the true role of these remarkable fossils in the evolutionary history of our planet lies in the continued expansion of research to consider the full range of Ediacaran organisms (rather than just a few iconic groups) and to use new techniques and data sets from other geological and biological disciplines.
