They are commonly found under ground or near volcanoes
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Extrusive, Igneous rocks possibly lavas or ignimbrites.
Extrusive igneous rocks are typically found at or near the Earth's surface, where magma erupts from volcanoes or fissures and cools quickly to form solid rock. Common locations include volcanic islands, lava plateaus, and areas around active or dormant volcanoes. Examples of extrusive igneous rocks include basalt and pumice, which can be found in regions with recent volcanic activity.
you would normally find igneous rock which is formed by cooled magma.
Geologists find it easier to study extrusive igneous rocks because these rocks form at or near the Earth's surface, allowing for direct observation and sampling. Their rapid cooling process often results in distinct textures and mineral compositions that can be more readily analyzed. In contrast, intrusive igneous rocks form deeper underground, making them less accessible and often requiring excavation or drilling to study. Additionally, the slower cooling of intrusive rocks can result in more complex textures that are harder to analyze in the field.

You would expect to find an igneous rock with small crystals near the Earth's surface where the rock cools relatively quickly, such as in volcanic eruptions or magma intrusions that do not have much time to grow large crystals. These rocks are known as volcanic or extrusive igneous rocks.

the fossils would be turned into another rock if it was in a metamorphic rock or igneous rocks. it requires a blanket of sediment

Obsidian is an extrusive rock and is formed from rapidly cooling magma. Obsidian is also known as volcanic glass and one can find only sub-microscopic crystals in it. This is because it was cooled too fastly for large crystals to form. If the material that obsidian consists of were an intrusive rock and had a lot of time to cool down, one would find that it would be composed of easily visible crystals.
If you were to tunnel into the crust of the Earth, you would most likely find igneous rocks. These rocks are formed from the solidification of molten magma below the Earth's surface. Examples of igneous rocks include basalt, granite, and diorite.
you will find it in earths mantle because it is a kind of an igneous rock
