The correct answer is: Stromatolites
Stromatolites are widely accepted as the oldest fossils. The oldest stromatolite is estimated to be around 3.5 billion years old. These fossils were formed by cyanobacteria, the ancient blue-green algae. Most of the stromatolites identified so far are old and dead. In 1956, extremely rare living stromatolites were identified from the Hamelin pool of Western Australia.
