Microfossils up to almost 4.3 billion years old found by researcher. It was primordial microbes as per recent study. That set in motion the evolutionary march toward complex life. Researchers reported that these may be the oldest fossils ever discovered. Remains of bacteria thriving on Earth not long, geologically speaking after the very birth of the planet.

Key Highlights

  • Microfossils up to almost 4.3 billion years old have been found.
  • Origin: The fossils from Hudson Bay shoreline in northern Quebec near the Nastapoka islands explained that hydrothermal vents led hot water and created life on Earth soon after the planet was formed
  • Traces: Tiny filaments and tubes made of a form of iron oxide formed by the microbes were found encased in layers of quartz. It is estimated that microfossils would be between 3.77 billion and 4.28 billion years old
  • Earth formed about 4.5 billion years ago and oceans appeared about 4.4 billion years ago. These occurred 4.28 billion years ago and indicates “instantaneous emergence of life”
  • Known as “dubiofossils” that is fossil like structure without clear proof about there origin
