Some rocks are old.These sometimes have fossils.This is because the rocks used to be mud.When a inprint is made on the mud and does not get washed away the mud hardends the inprint stays.Years later the inprinted mud turns into a rock.If you get lucky and crack that rock open, the inprint is there.

Which type of rock igneous or metamorphic contains fossils?

Metamorphic rocks do not typically contain fossils, as the intense heat and pressure involved in their formation often destroy any remnants of organic matter. Igneous rocks are formed from molten material and do not contain fossils. Sedimentary rocks, which form from the accumulation and compression of sediments, are the type of rock that commonly contain fossils.


What type of rocks can contain fossils on them?

Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.


Does igneous sedimentary and metamorphic rocks contain fossils?

No. In general, there are no fossils in igneous or metamorphic rocks, because the high heat and pressure involved would destroy any fossils. Fossils are almost always found in sedimentary rock.


What do sedimentary rocks have more often than metamorphic or igneous rocks?

Sedimentary rocks often have visible layers or bedding, which are less common in metamorphic or igneous rocks. Sedimentary rocks also tend to contain fossils, as they are formed from the accumulation of sediments. Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.


What types of rocks contain fossils?

Igneous rocks and most metamorphic rocks, of an igneous origin.


Do sedimentary rocks contain fossil?

yes fossils are found in sedimentary rocks but not in igneous and metamorphic rocks. hope this helps


More often than metamorphic or igneous rocks sedimentary rocks have what?

Sedimentary rocks have numerous fossils


Which rocks would most likely contain a fossil in rock and minrol?

Sedimentary rocks, such as shale, sandstone, and limestone, are most likely to contain fossils. These rocks form from the accumulation of sediment and often preserve the remains of plants and animals. Fossils are less commonly found in igneous and metamorphic rocks, as these rocks form from molten material and intense pressure and heat, which usually destroy any existing fossils.


What types of stones are most likely to contain fossils?

There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.


What is the importance of sedimentary rocks?

They Often Contain fossils.


What are the types of rock that contain fossils?

Sedimentary rocks, such as limestone, sandstone, and shale, are the most common types of rocks that contain fossils. Fossils are formed when the remains of plants and animals are buried in sediment and eventually become preserved in rock over time. Igneous and metamorphic rocks typically do not contain fossils.


Do many metamorphic rocks have fossils in them?

it shows fossils because when sedimentary rocks are formed waste and decayed matter get cement( crushed ) togather. The change of mineral forms metamorphic rocks, but the fossils will remain in the rocks only the minerals will change. eg Limestone ----- marble. Limestone forms marble which is used to build taj mahal.
