When an organism dies, its remains are exposed to various environmental factors, such as scavengers, decomposition, and weathering. For fossilization to occur, the remains must avoid rapid decay and destruction. 2. Rapid Burial: One of the critical factors in fossil formation is rapid burial. "Previous tests on dinosaur feathers, though, found mostly alpha-proteins.
