As with all exploratory science, the answer to the oldest fossil changes with time, as new discoveries and evaluation techniques are made.
The Gunflint Chert along the northern shore of Lake Superior, produces definite fossils, and these date to about 2.0 Ga ago (Ga = 10^9 years). Other sites also lay claim, and of course the determination of these very early fossils is difficult, if not actually uncertain.
A site in Western Australia at Warrawoona, also produces probable early fossils from about 3.4Ga ago. Sites in Canada and India also show promise of very early life forms. Amazingly enough one of these early organisms, a blue-green algae helps form Stromatolites, and a famous site where they may still be seen growing, is at Shark Bay in NW Australia. [That is not to suggest that the individuals from long ago are still living.]
And of course, Antarctica still largely remains to be discovered.

Dinosaur fossils have been found on every continent except?
Dinosaurs have been found on all 7 continents, even Antarctica.
Where are most fossils found-?
Fossils can be found all over the world, usually in sedimentary rock, which comprises the bedrock of the majority of the planet. Limestone and shale are particularly good fossil medium.
Most fossils are found and what type of rock?
Sedimentary
Where are fossils commonly found?
FOSSILS according to scientist fossils are most likely to be found in the united states (caves mountains and lots of other places) u might fall and trip on one
What fossils are most likely to be found in rocks?
Fossils of marine animals like ammonites, trilobites, and brachiopods are commonly found in sedimentary rocks. Plant fossils such as leaves, stems, and pollen are typically found in rocks as well. Fossils of dinosaurs and other land-dwelling animals are more commonly found in sedimentary rocks that were formed in terrestrial environments.
What continent have the oldest fossils been found?
Africa
What continent have the old fossils been found on?
Africa
On what continent were the earliest fossils found?
I think Africa, which is why it is referred to as the cradle of life.

What continent did dromaeosaurs live on?
Dromaeosaurs lived on every continent except Australia. However, dromaeosaur fossils have even been found in Antarctica.
What rock are most marine animal fossils in?
The most marine fossils are found in sedimentary rock
What types of fossils are most likely to be found?
fish fossils and little animal fossils and also shells
What environments can fossils be found in?
Fossils can be found in all types of environments, though most of the recent finds were in deserts.
How do fossils help support the theory of continental drift?
Fossils found on separated continents provide evidence that those landmasses were once connected. Similar fossils on continents that are now far apart suggest a shared history and support the idea of continental drift. Additionally, the distribution of fossils across continents can help reconstruct the movement of landmasses over geological time.
When has the most fossils been found?
Arizona
Why have so few dinosaur found in Antarctica?
So few dinosaur fossils have been found in Antarctica because the entire continent is covered in ice, making it hard to dig and/or search for large fossils.
What types of rocks are fossils most likely to be found?
fish fossils and little animal fossils and also shells
