Do igneous rocks have fossils?
Igneous rocks form from molten rock, and rarely have fossils in them. Generally it is only sedimentary rocks that contain fossils.
What are fossilized rocks?
Updated April 24, 2017. By Venice Kichura. Fossils are prehistoric hard-rock remains or traces of plants or animals preserved in sedimentary rocks. Some of the plants or animals existed as far back as millions of years ago. Usually fossils are preserved by being buried underneath multiple layers of sand of mud.
What is the difference between rocks and fossils?
Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. A fossil can preserve an entire organism or just part of one.
Can metamorphic rocks contain fossils?
Metamorphic rock, such as marble, is formed by tremendous heat and pressure. Fossils are not usually found in either igneous or metamorphic rocks.
What type of rocks can contain fossils on them?
Of the three major types of rock formations (igneous, sedimentary, and metamorphic), sedimentary rocks are most likely to contain fossils. Fossils are formed when the bodies or remnants of living…
What type of rock is more likely to hold fossils?
Because sedimentary rocks are subjected to the least extreme environments and form where living organisms are, they are the type of rock that is most likely to contain fossils. This doesn’t mean that other rock types don’t have any fossils, just that sedimentary rocks most commonly have fossils.
What type of rock is good for forming fossils?
Sedimentary rocks, unlike igneous and metamorphic rocks, are formed by the gradual deposition and cementation of the material over time. Such rocks provide ideal conditions for fossils because plant and animal remains can be covered by layers of materials over time, without destroying them.
What is rock that may contain fossils?
Finally, the sedimentary rocks are the one type which can contain fossils because these rocks are formed on the Earth surface, under the water, at very low temperatures and pressures.
