Since the beginning of time, mainly dinosaurs.
A long time ago
Most animals that became fossil fuels (coal, oil and natural gas) were tiny plankton in the oceans. Coal was made from larger vegetation and possibly animals like archosaurs, the reptile ancestors of the dinosaurs.
because you can't live when there is fossil fuels in the air.
organic matter
no. As Fossil Fuels are the ancient remains of animals and plants, they only occur where they used to live. There aren't any in Iceland, as much of it is volcanic rock formed fairly recently, but there was much in America, as it is old ground that was home to many creatures, such as Dinosauria.
The fossil record is incomplete.
live animals and plants, which later died and eventually became fossilized
it can make it harder for them to live because fossil fuel give off smoke which can help in global warming and can long turn make it harder for animals becuse the ecosystem will change.
oil, which is pretty suprising... merf.
Fossil Fuel Power Plants were created when.....
Fossil fuels are formed from the remains of ancient plants and animals, which required water to grow and live. In the case of coal, swamps and wetland environments helped preserve plant matter without fully decomposing it. In the case of oil and natural gas, marine organisms in oceans and seas trapped carbon-rich organic material that eventually turned into hydrocarbons.
All herbivores animals eat plants. They live on plants.
