Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

Estimated to be between 700,000 and 1,490,000 years old, it was, at the time of its discovery, the oldest hominid fossil ever found, and it remains the type specimen for Homo erectus. Led by Eugène Dubois, the excavation team uncovered a tooth, a skullcap, and a thighbone at Trinil on the banks of the Solo River in East Java.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
The oldest fossils from 8.9 million years ago included megalodon teeth. Megalodon sharks were massive, and so were their teeth. Those shown here belonged to juveniles.
A near complete skull fossil found in Antarctica has revealed the oldest known modern bird — a mallard duck-size creature related to the waterfowl that live by lakes and oceans today, a new ...
Before Homo sapiens, Homo erectus had already spread throughout Africa and non-Arctic Eurasia by about one million years ago. The oldest known evidence for anatomically modern humans (as of 2017) are fossils found at Jebel Irhoud, Morocco, dated about 360,000 years old.
SAO JOAO DO POLESINE, Brazil (Reuters) -Scientists in Brazil announced the discovery of one of the world's oldest fossils believed to belong to an ancient reptile dating back some 237 million ...
Bicellum brasieri is a fossil holozoan. [1] It is one billion years old and could be the oldest example of complex multicellularity in the evolutionary lineage leading to the animals, [2] [3] and has been described as bridging "the gap between the very first living creatures — single-celled organisms — and more complex multicellular life."
