Question

Quizplus · Accepted Answer

Fossils are primarily found in sedimentary rocks which are formed by deposition and accumulation of sediment. The organic or fossil remains get buried, and this over time turns into sedimentary rock. Igneous rocks are formed by solidification of molten material, and metamorphic rocks are formed by alteration or transformation of existing rocks under high pressure and temperature. Therefore, fossils are not usually found in these types of rocks. Crystalline rocks typically refer to any rock with a crystal structure and can be categorized into any of the other three rock types.
