Ediacarans.

The transition to the diverse and complex biosphere of the Ediacaran and early Paleozoic is the culmination of a complex history of tectonic, climate, and geochemical development.The Ediacaran Period, predating the Cambrian explosion, is a treasure trove of early life forms. Among its discoveries are ancient phyla like the soft-bodied Ediacarans, ancestors to modern sponges, and mysterious organisms that challenge our understanding of life's evolution. How did these life forms shape our planet's biological legacy?The Ediacaran Period is an interval of geological time ranging 635 to 541 million years ago. During this time there was immense geological and biological change. There was a transition from a life largely dominated by microscopic organisms to a world swarming with animals.

The Ediacaran Period (635-542 million years) represents a turning point in the history of life with the advent of the first large and complex multicellular soft-bodied organisms. These include sponges and cnidarians, as well as a number of problematic groups represented by both macrofossils and microfossils.
