The Ediacaran Biota refers to a group of ancient organisms that lived during the late Precambrian period, approximately 635 to 541 million years ago. These organisms are some of the earliest complex life forms and are primarily found in sedimentary rocks from this era. They exhibit a variety of shapes and sizes, with many resembling modern jellyfish, worms, and fronds. Ediacaran organisms are significant because they represent a crucial step in the evolution of life on Earth, preceding the Cambrian Explosion, which saw a rapid increase in biodiversity. Fossils of the Ediacaran Biota provide valuable insights into early multicellular life and the environmental conditions of the time.
