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.

Ming (c. 1498 or 1499–2006), also known as Hafrún, was an ocean quahog clam (Arctica islandica, family Arcticidae) that was dredged off the coast of Iceland in 2006 and whose age was calculated by counting annual growth lines in the shell. Ming was the oldest individual (non-clonal) animal ever discovered whose age could be precisely determined.

Pikaia gracilens is an extinct, primitive chordate marine animal known from the Middle Cambrian Burgess Shale of British Columbia.Described in 1911 by Charles Doolittle Walcott as an annelid, and in 1979 by Harry B. Whittington and Simon Conway Morris as a chordate, it became "the most famous early chordate fossil", [1] or "famously known as the earliest described Cambrian chordate". [2]
