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.

One found in a Pleistocene squirrel burrow in the Duvanny Yar outcrop on the Kolyma River was believed to be about 32,000 years old, while the other, recovered in 2015 near the Alazeya River, was dated at approximately 30,000-40,000 years old. These nematodes were believed to be the oldest living multicellular organisms on Earth.
The stump (lower left) and some remains of the Prometheus tree (center), in the Wheeler Bristlecone Pine Grove at Great Basin National Park near Baker, Nevada. Prometheus (recorded as WPN-114) was the oldest known non-clonal organism, a Great Basin bristlecone pine (Pinus longaeva) tree growing near the tree line on Wheeler Peak in eastern Nevada, United States.
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to mammals — fills a longstanding gap in the fossil record.
Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution ...
Formation of a greenstone belt of the Acasta Gneiss of the Slave craton in northwest Canada - the oldest known rock belt. [28] 3900–2500 Ma Cells resembling prokaryotes appear. [29] These first organisms are believed to have been chemoautotrophs, using carbon dioxide as a carbon source and oxidizing inorganic materials to extract energy. 3800 Ma
Ming was the oldest individual (non-clonal) animal ever discovered whose age could be precisely determined. [1] [2] [3] Thought to be 405 years old, Ming was later determined to be 507 years old, although the clam had previously been killed to make this determination. The size of the clam was 87 mm × 73 mm (3.4 in × 2.9 in).
A uniquely preserved prehistoric mudhole could hold the oldest-ever human footprints on the Arabian Peninsula, scientists say. The seven footprints, found amidst a clutter of hundreds of ...
