Which of the following rocks would most likely contain a fossil?

Question

granite
marble
basalt
limestone

Answer 1

Limestone would most likely contain a fossil. Fossils are commonly found in sedimentary rocks, and limestone is a sedimentary rock formed primarily from calcium carbonate, often derived from the remains of marine organisms. In contrast, granite and basalt are igneous rocks, and marble is a metamorphic rock, both of which generally do not contain fossils.
