There was no oxygenated atmosphere on primordial Earth, and thus no ozone layer to protect early life from the sun's ultra-violet rays. The oceans, however, did offer some protection and so it follows that the waters were the cradle of life.
The first organisms, (cyanobacteria), produced oxygen by means of photosynthesis. It took more than 3 billion years for cyanobacteria and archaea to produce an atmosphere, oxygenated oceans and soils fit for eukaryotic life.
The marine fossils that are found in the Alps were once on the bottom of the ocean. Plate collision has resulted in their uplift.
Marine organisms.
uplift associated with plate tectonics
Small shelled marine organisms are the most common easily observable fossils found in rocks.
Coal
Fossils are formed from the buried remains of marine organisms. These organisms are under a tremendous amount of pressure and, over time, they fossilize.
The cliffs are chalk, a form of limestone from the remains of small ancient marine organisms.

Fossils exist of nearly all formerly living organisms, with some exceptions, from single celled bacteria to the largest dinosaur. Marine organisms comprise the bulk of fossils that are easily available today.
Yes, fossil fuel is formed from fossils.
Petroleum is formed under Earth's surface by the decomposition of marine organisms. The remains of tiny organisms. EW!
The dead marine organisms are oil and gas now and the people used them for gas and fuel cost companies.
No, it is formed when forests die and are covered with layers of rock which compress it and over time turns it into coal. Buried remains of marine organisms formed oil, following mass extinctions,where the oceans have stagnated.
