people who specialize in rock fossils are called paleontologists
layer rocks
Strictly speaking these are two differing types of scientists. Petrologists study rocks and paleontologists study fossils. However both these disciplines are covered in the broader training of a geologist.
In rocks in most parts of the Earth.
Sedimentary rocks layers.
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
mantle
The Asthenosphere.
the outer most layer of earth is CRUST
they have fossils and pieces of the environment from the past inside of them
The crust because that is the outer layer and we live on the crust so... there are rocks on the layer we live on! The answer is Crust.
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
It depends what fossil you're talking about but normally fossils are found in sedimentary rocks. But diatomaceous earth, and limestones contain fossils, or are made of fossils.
