The Vendian Period, also known as the Ediacaran Period, was the final geologic period of the Neoproterozoic Era before the Cambrian Period. It lasted from about 635 million to 541 million years ago and is known for the appearance of complex multicellular life forms, including the earliest known animals.
During the Tertiary period, dominant organisms included early mammals, large birds, marine mammals like whales and dolphins, and diverse plant species. This period saw the rise of modern mammals, along with the evolution of grasslands, forests, and flowering plants. The Tertiary period also saw the decline of dinosaurs and the rise of more familiar animal groups.

It is possible that multicellular animals existed before the Vendian Period. Like the Vendian animals, earlier animals may have been soft-bodied, so they did not leave fossils. Or, paleontologists simply may not yet have found any earlier fossils.
