Where are older fossils mostly found under or above younger fossils?

If the rocks containing the fossils have been involved in a mountain building episode they would be folded and if some of the folds were laid in a recumbent position and later eroded you would have older above younger rocks. Of course, it would be easy to find out if this was the case because of the various sedimentary structures in each separate layer of rock.

Where have dinosaur fossils been found?
Mostly around South America, Africa and Asia
What type of water are fossils mostly found in?
Fossils are not found in water, but rather in the sediment deposits which includes the bottom of a body of water. Fossils are especially prevalent in shallow marine environments where they may become well preserved.
Why would fossils found at the top of a canyon probably be younger than those found at the bottom of the canyon?
The fossils found at the top of a canyon will probably be younger than those at the of the bottom of the canyon because the fossils at the bottom of the canyon would have been there earlier when the so called "canyon" was once a flat land, so as time went by, the flat land began growing and getting taller and finally became a canyon so the fossils at the top of the canyon WOULD be younger than those at the bottom because the bottom fossils were there before the top of the canton even existed.
Where can you find the oldest fossils in sedimentary rock layers?
It would be found in the lower layers, rather that younger fossils which are found in the upper layers. ♥
Fossils found in younger rocks?
The youngest rocks would be igneous, those created by cooling magma. Impossible to find a fossil there.
Where are fossils mostly preserved?
Most fossils are found in sedimentary rock, which is the most common type of rock on Earth. Sedimentary rocks form when particles of sediment are deposited by water or wind, and then hardened over time.
