Often, but not always!
The definition of a fossil is a whole, part or impression of an organism from a past geologic age, embedded in natural materials, such as rock, sediment, resin, petrified bones, or wood.

∙ 13y agoFossils could be found in extrusive igneous, meta-sedimentary, or sedimentary rocks. You would not expect to find fossils in intrusive igneous or meta-intrusive-igneous (I kinda just made that word up) rocks.

Rocks are composed of minerals in various combinations and percentages and are the results of a very wide range of temperatures and pressures that acted upon the combination of minerals to form one of three kinds of rock; Igneous (great heat, enough to make the minerals melt and flow); metamorphic (a pre-existing rock is subjected to pressure and heat great enough to alter the mineral content and their relationships but not enough to liquify them) and sedimentary ( water and wind erode existing rock without altering mineral content significantly or minerals of one kind are precipitated from water) Fossil remains are usually formed by an animal or plant as a covering or protection. They are found mainly in sedimentary rocks as part of the load moved by water as the rocks form. Most fossils are CaCO3 or SiO2 and vertebrate animal bones are CaPO4 or variants of calcium phosphate. These minerals formed by organisms are a component of a rock. Plant tissues too are fossilized.

Wiki User
∙ 14y agoA fossil is any record of an organism preserved in rock, whether it be igneous, sedimentary, or metamorphic. Nearly all fossils are discovered in sedimentary rock.
Wiki User
∙ 15y agoA rock cannot be a fossil, but it can have a fossil in it. Rocks are composed of one or more minerals while fossils are the remains or traces of organisms from the past.

∙ 13y agoNo not really. Unless it contains the bones or parts of a deceased organism from the past, then no. Rock is just .. rock.

What does the principle of superposition tell you about the relative ages of sedimentary rock layers?
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
What environment does a turtle live in?
There are many different types of turtles, which can be found on land or in water. They are found in different types of climates, including temperate climates.
What 3 requirements do index fossils have?
To be an index fossil, it must be widespread, commonly found (sometimes in groups) and have a short life span for which it lived. If a fossil meets all three of these requirements, it is considered an index fossil.
Discuss how fossils provide evidence of change from the earliest life-forms to those alive today?
Fossils showing animals of the past display some similarity to animals of today as well as some differences. When we start at the bottom of the fossil record (where all the oldest fossils are) and work our way up through all the rock layers of the different ages in geologic time, we start to notice the changes in the fossils and how they lead up to the animals of today
Why are fossils found were no ocean exist?
alright, think about what were most modern desets in prehistoric times, they were all majors bodies of water. So it stands to reason that if there was a mojor body of water there and all the marine life in that water died, and that water receeds or dries up it would leave behind all the bones and skeletons of everything that once lived there in the sand, which is now a desert. Weird how that works huh?
Are fossils abundant in all types of rocks?
no they are not. If you go outside and look around and look at all types of rocks you will probably not find a fossil. Fossils are rarely found.
What environments can fossils be found in?
Fossils can be found in all types of environments, though most of the recent finds were in deserts.
Do all rocks form fossils?
No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.
What are non examples of fossils?
Some examples of non examples of fossils are as follows: knobby rocks, beautiful stones, bones. All fossils are rocks, and if bone fossils are found they will be much heavier than normal bone.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Where are most fossils found-?
Fossils can be found all over the world, usually in sedimentary rock, which comprises the bedrock of the majority of the planet. Limestone and shale are particularly good fossil medium.
What are the remains of once-living orgainismsfound in sedimentary rocks?
All fossils are found in sedimentary rocks. Some sedimentary rocks are made of nothing but fossils such as chalk. A creature ( microscopic or larger) skeleton is deposited after death usually on the ocean floor. Sediments cover it, and over time turns into a fossil.
Are fossils found in rocks all over the world?
Yes. Though they will vary according to the index fossil.
What are the types of evidence that support evolution?
\that the animals can be found all around the world fossils
Facts about sedimentary rocks?
95or all fossils found. Sedimentary rock makes up ¾ of the earth's surface.
How can the age of a rock be related to fossils?
If a lava flow or bed of volcanic ash was dated using isotopic dating methods and fossils were found in a sedimentary rock beneath the volcanic rock, it can be surmised that the fossils were older than the lava or ash. If the same species of fossils were found in another part of the world it would make sense that the rocks there were the same age as previous fossils. By cross checking with many other areas with other volcanic rocks, it can be found that all the rocks around the world containing those fossils were of a similar age.
What kind of information can be found in rocks?
A lot of different things, from fossils all the way to what exactly was in that location a long time ago.
