what are fossils and where do they come from,
Fossils are typically found in sedimentary rock, almost all of which were originally deposited as sediments by moving water.Subsequent processes hardened them into sedimentary rock, as overlying pressure squeezed the water out and the grains were cemented together.ossils are typically found in sedimentary rock, almost all of which were originally deposited as sediments by moving water.
Where Fossil Fuels Come From. There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs â hence the name fossil fuels.The age they were formed is called the Carboniferous Period.ome deposits of coal can be found during the time of the dinosaurs. For example, thin carbon layers can be found during the late Cretaceous Period (65 million years ago) â the time of Tyrannosaurus Rex. But the main deposits of fossil fuels are from the Carboniferous Period.
