While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.

Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.
A theory that states that only the organism with traits that are useful to the environment survive. For example, short-neck giraffes would’ve died out years ago as they can’t reach the trees nor eat grass on the ground.

Decaying matter is called compost
