The ferns have been compressed into 'coal' and we use coal as a source of energy - hence 'fossil fuels'.
i think its from the energy stored by plants that lived hundreds of millions of years ago.=]
What we find as crude oil underground today was formed by millions of years of chemical reactions from the decay of plants that lived long ago. Most of them were palms and ferns.
Ferns were the dominant form of vegetation during the Carboniferous Period about 300 million years ago. They were much larger than ferns growing today, some reaching a height of 24 meters (80 feet). Much of the world's supply of coal, oil, and gas formed from the remains of ancient ferns that were slowly buried under layers of sediment.
ferns and leaves
Velociraptor lived in a desert, so most plants only lived at oases or were very sparsely scattered. Plants that may have lived there include conifers, cycads, ferns, ginkgoes, horsetails, and early angiosperms such as primitive grasses and palm trees.
Fossil Fuels such as coal, oil, and natural gas.
grass, wheets, beech tree's oak trees, and ferns
they have lived for up to millions of years
Fossils can show the kind of environment animals lived in millions of years ago. They can also show how certain animals have evolved. Artifacts can show the kind of society humans lived in at a certain time.
Oil, is a fossil fuel, which is made from small organisms that lived in shallow inland seas and oceans, that once lived hundreds of millions of years ago. The creatures decompose and the oil is the energy of that dead animal.
Dinosaurs lived tons and tons of years. For me I think that they lived for millions and millions of years.
Millions of buffalo.
