What do you know about a rock layer found on a mountain if you find a seashell fossil?
If you find a seashell fossil in a rock layer on a mountain, than you know that the rock layer was formed at a time when that area was submerged under water. This is because the seashell lived and died underwater, so it would have been fossilized there as the rock layer formed. Millions of years later, the water drained away, and forces within the Earth's crust pushed the rock layer and the layers above it upward, forming mountains. Of course, the rock layer would have been buried deep within the Earth by that point, but as the mountains formed, weathering and erosion would have worn away the newer layers, exposing the ancient rock layer with the seashell.

How can a fossil of an aquatic animal be found in a layer of rock through a mountain about sea level?
The layer of rock containing the aquatic animal fossil was likely formed underwater millions of years ago before the mountain uplifted. Over time, tectonic forces pushed the rock layers upwards to form the mountain, including the layer with the aquatic animal fossil, which is now visible at or near sea level due to erosion.
What layer is an old fossil found?
Fossils are typically found in sedimentary rock layers, which are formed from the accumulation of sediments over time. Fossils are most commonly found in the mid to lower layers of sedimentary rock formations. The specific layer in which a fossil is found depends on the age of the fossil and the geological history of the area.
What could you conclude if a dinosaur fossil and a bird fossil were found in the same layer of rocks?
We would conclude that the bird and the dinosaur lived around the same time.
What principle is a geologist applying when deciding that a fossil in a mud layer is older than a fossil in a sandstone layer above it?
The geologist is applying the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest rocks are at the bottom and the youngest are at the top. This helps geologists determine the relative ages of fossils found in different layers of sedimentary rock.
A fossil found under a layer of rock is usually?
older than the rock layer above it and can provide information about the time period in which it lived and the environmental conditions at that time. This helps scientists estimate the age of the rock layers and understand the history of the area where the fossil was found.

It is usually older than the rock layer it is found under.
What is a fossil found under a layer of rock is usually?
It is usually older than the rock layer it is found under.

The specific layer in which a fossil is found depends on the age of the fossil and the geological history of the area.
How do you tell how old a fossil is by the rock layer?
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
What could you conclude if a dinosaur fossil and a bird fossil were found in the same layer of rocks?
We would conclude that the bird and the dinosaur lived around the same time.
What type of dating would be used to determine the age of rocks by using the fossil?
By using the geologic time scale. Certain organisms are only found during certain times and if a fossil of one of these organisms is found then you can determine the relative age of the fossil.

A fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers?
This fossil is called a index fossil. It is a species that is easily recognizable, widespread, and existed for a short period of time. By determining the age of the rock layer where the index fossil is found, geologists can establish the approximate age of the surrounding rocks.
