What was the oldest fossil ever discovered in this world?

Question

Thank you for your answer

Answer 1

A specimen that has been sitting in the Museum's collection for over 60 years was recently confirmed as being the world's oldest fossil insect.

Insects have six legs which places them in the Superclass Hexapoda. This superclass contains two classes: the Collembola (springtails) and Insecta (true insects), which are separated on the form of the mouthparts.

Answer 2

The oldest confirmed fossils are cyanobacteria: which are found as far back as 3.5 thousand million years:  Stromatolites, or algal mounds, which are mounds build up by these cyanobacteria occur throughout the Archaen and are the only fossil known until about 1.0 Thousand million years ago.

Living stromatolites, which are mounds of material trapped by cyanobacteria can still be found today in certain restricted environments, e.g. at Shark Bay in Australia.

Answer 4

Blue -green algae from the WarraWoona group in Western Australia.

"Cellularly preserved filamentous and colonial fossil microorganisms have been discovered in bedded carbonaceous cherts from the Early Archean Apex Basalt and Towers Formation of northwestern Western Australia. The cell types detected suggest that cyanobacteria, and therefore oxygen-producing photosynthesis, may have been extant as early as 3.3 billion to 3.5 billion years ago. These fossils are among the oldest now known from the geologic record; their discovery substantiates previous reports of Early Archean microfossils in Warrawoona Group strata."
