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.
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Rocks, sediment, and soil contain different kinds of fossils, which are the preserved remains or traces of ancient plants and animals. Fossilized bones, shells, imprints, and tracks can all be found in various types of sedimentary rocks.
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.
Mold fossils- an empty space is left when an organism is buried in sedimentary and it decays.Cast fossils- Minerals in rocks fill space left by a decayed organism.(replica)Trace fossils- Markings left by an animal. (footprints, trail, or burrow)Petrified fossils- Minerals penetrate and replace all or part of an organism.Imprint fossils
all gen.4 fossils by breaking rocks (rock smash)
Fossils abound in sedimentary rock, you are in fact very likely to find them there.

Fossils, rocks, and the Theory of continental drift are all connected because when the continents moved apart from each other, the spreading actually moves the rocks and fossils to another area, resulting in rocks that fit perfectly together but were separated and many similar fossils in different areas. hOPE IT HELPS ;)
To know all about rocks and fossils and their rock cycle.
Terrestrial rocks and extraterrestrial 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.
