This molecule is ATP (adenosine triphosphate ). It is a complex composed of the nucleoside adenosine and a tail consisting of three phosphates.
As far as known, all organisms from the simplest bacteria to humans use ATP as their primary energy currency. The energy level it carries is just right amount for most biological reactions.
The total human body content of ATP is only about 50 grams which must be constantly recycled everyday. Energy is usually liberated from the ATP molecule to do work in the cell by a reaction which removes one of the phosphate groups.
Fossils give clues about environmental changes where the organism lived, fossils can be used to date the time period of rocks and rock layers when the organism lived, fossils can give clues of changes in the organism's body structure over time.
