Why do rock fossils form in sedimantry rock and not in igneous rock?

Fossils usually form when the remains of an organism are buried gently under sediments which later turn into stone.
Intrusive igneous rocks form at depths within Earth where no life is found. Extrusive igneous (volcanic) rocks are so hot when they are deposited that any remains of organisms are usually incinerated. Fossils do occur in volcanic rocks, but very rarely.
