There are sea fossils at the top of the canyon from the seas that once covered the low plains there.
Large plate tectonics or the fossils had wings.
Fossils found in rock at the top of mountains indicate that the rock was once at the bottom of a body of water because the fossils are typically of marine organisms that lived in water. The presence of marine fossils in mountain rock suggests that the rock was uplifted from below sea level to its current position at the mountain top over millions of years.

The fossils are typically found in the uppermost layer of rock, as sedimentary rock is formed from the accumulation of materials over time. Newer layers are deposited on top of older layers, meaning that the youngest fossils would be located in the most recent (top) strata. Therefore, the youngest fossils are in the layer that is highest in the sequence shown.
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.

There are perso fossils in Parchment Desert.
They are called index fossils, fossils of organisms that were widespread, evolving quickly, and only appeared in the geologic column for a specific length of time.
The fossil on the bottom would be older because as time goes on rock builds up and buries fossils so the higher it is the more recent it is.
Africa has the most countries on the list of the top 10 countries with the most number of countries.
We read the Geologic timescale from the bottom to the top because, that is the same way geologists and paleontologists had found the older fossils. The older fossils lay at the bottom, and the more younger ones, near the top.
