Fossils are most common in which rock types?
A
sedimentary
B
igneous
C
metamorphic
D
all of these commonly contain fossils
Explanation: 

Detailed explanation-1: -Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils.

Detailed explanation-2: -Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks.

Detailed explanation-3: -Therefore, fossils are found in sedimentary rock, like sandstone, shale, limestone and coal. Igneous rock, like granite and basalt, is formed by molten rock erupting from deep within the earth.

Detailed explanation-4: -Since sedimentary rocks are formed by the pressure of a body of water above them, animals that die and fall into a river or lake or ocean have a higher chance of becoming fossilized in the sediment. Over millions of years, the minerals replace the organic material and they turn into fossils.

Detailed explanation-5: -Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans.
