In what type of rock are fossils most likely to be found : Igneous, Metamorphic or Sedimentary ?

Fossils are more likely to be found in sedimentary rock
and here are the reasons why.

Contrary to igneous and
metamorphic rocks, sedimentary rocks do not change. Their name itself indicates that
they pretty much have remained in the same place and state for
centuries.

In the same line of thought, igneous rocks often
are remains of volcanic eruptions or have been transformed by heart and erosion.
Metamorphic rocks are like igneous rocks in that they have mixed with other rocks, have
been crushed and mixed and also have been affected by extreme
temperatures.

Therefore sedimentary rocks, either because
of their location and the fact that they do not come from any volcanic activity, are
more likely to remain the same and therefore whatever fossil that will be imprinted in
it will undoubtedly do it easier in such a type of unchanging
rock.
