Most fossils were likely formed during the Paleozoic Era, which lasted from about 541 to 252 million years ago, particularly in the Cambrian and Ordovician periods when diverse marine life was abundant. However, significant fossilization also occurred during the Mesozoic Era, known for the age of dinosaurs, and in the Cenozoic Era, which includes the rise of mammals. Fossilization typically requires specific conditions, such as rapid burial and low oxygen environments, making it more likely in sedimentary rock formations.
What else can I help you with?
In what type of rack do most fossils form?
Most fossils form in sedimentary rock, which is formed from layers of sediment that build up over time. This process preserves the remains of plants and animals, creating fossils.
Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
What kind of rock is the site of most fossils?
Sedimentary rock is the most common type of rock that contains fossils. Fossils are formed when the remains of plants and animals are buried in sediment, which hardens into sedimentary rock over time, preserving the fossilized organisms.
Most fossils are found in what A in rock layers which formed underwater b in rocks which were formed from cooling lava from volcanoes c in sand on seashores d in the waters of seas and lakes?
A. in rock layers which formed underwater
What layer is an old fossil found?
Fossils are typically found in sedimentary rock layers, which are formed from the accumulation of sediments over time. Fossils are most commonly found in the mid to lower layers of sedimentary rock formations. The specific layer in which a fossil is found depends on the age of the fossil and the geological history of the area.

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.

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.
