Older fossils may not always be found at the bottom layers of rocks due to geological processes like folding, faulting, or erosion, which can disrupt the original order. In these cases, older fossils may be found at higher layers while younger fossils are found in lower layers.

In the Grand Canyons the oldest fossils are found where?

The oldest fossils in the Grand Canyon are found in the layers of sedimentary rock near the bottom of the canyon, dating back around 1.2 billion years ago. These fossils provide insights into early life forms and the geological history of the region.


Where can you find the oldest fossils in sedimentary rock layers?

The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.


Do evolutionists say the oldest fossils are at the top or at the bottom of the fossil record?

there pretty much at the top fossils cant be to far down on the bottom of the earth but who knows what evolutionist say I'm not them and may God Bless them, but that is my conclusion and if my answers wrong please feel free to change my answer.THANK YOU : )


Where are the oldest layers of sediments located?

The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.


Where would the oldest fossils be found in the rock layers?

The furthest down of all top layers.


In the grand canyon the oldest fossils are found?

What is the Arrangement of rock layers based on their ages?

A geologic column is an arrangement of rock layers in which the oldest rocks are at the bottom. The upper part of the column is rich in fossils.


What can the law of superposition determine?

The law of superposition can determine the relative ages of rock layers or fossils in a sequence. It helps geologists understand the order in which geological events occurred, with the oldest layers at the bottom and the youngest at the top.


What is the Principle is based on the fossils found in the different layers of sediment formations?

The principle is known as the Law of Superposition. It states that in undisturbed layers of sedimentary rock, the oldest rocks are found at the bottom and the youngest rocks are found at the top. This principle helps geologists determine the relative ages of rock layers and the fossils they contain.


Dating technique involving compraring fossils in rock layers?

Relative dating-comparing fossils related to how old other fossils are in the same sample of rock. If the rock has been undisturbed, the oldest rock will be at the bottom, therefore, the oldest fossils will also be at the bottom. the youngest rock will be at the top, therefore, the youngest fossils will be at the top. Absolute Dating-When you can figure out through testing the exact age of the fossil


How are rock layers arranging the geologic column?

The oldest rocks (layers) are at the bottom. The youngestrocks (layers) are at the top
