Are there fossils in shale rock?
Fossils are also common in shales which form from muds. Excellent imprint fossils can be formed in fine-grained sediments like muds. Only some shales contain fossils however because many areas of muddy ocean floor had conditions that were not suitable for animal life.
Why are fossils found in sedimentary rock?
Earth contains three types of rocks: metamorphic igneous and sedimentary. With rare exceptions metamorphic and igneous rocks undergo too much heat and pressure to preserve fossils. So most fossils are found in sedimentary rocks where gentler pressure and lower temperature allows preservation of past life-forms.

Is My rock a fossil?
something becomes a fossil it mineralized or becomes made of minerals. … Paleontologists also examine the surfaces of potential fossils. If they are smooth and do not have any real texture they are probably rocks. Even if it is shaped like a bone if it does not have the right texture then it is probably a rock.

What is rock and types of rock?
There are three kinds of rock: igneous sedimentary and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air or by precipitation of minerals from water. They accumulate in layers.
Is shale a sedimentary rock?
Common sedimentary rocks include sandstone limestone and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried the sediments lose water and become cemented to form rock.
What is limestone rock?
Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils shell fragments and other fossilized debris.
