Can you find fossils in metamorphic rock?
Metamorphic rock, such as marble, is formed by tremendous heat and pressure. Fossils are not usually found in either igneous or metamorphic rocks.
Why do you sometimes find fossils in metamorphic rocks?
Why does a fossil have to be present in the original sedimentary rock so that a fossil can be found in a metamorphic rock? A fossil must be present since the higher temperature and pressure needed to form metamorphic rocks will change the fossil minerals into something else.
Why do we find fossils in sedimentary rock?
Fossils are never formed in sedimentary rocks, they are only preserved. So the reason we tend to see fossils mainly in sedimentary rocks is because if you have some type of marine life die, it will sink to the bottom and eventually become covered in sediment.
Which of the following rocks Cannot have fossils?
Igneous rocks do not contain any fossils. This is because any fossils in the original rock will have melted when the rock melted to form magma.
Where do you find fossils?
Fossils are mostly found where sedimentary rocks of the right age are exposed, such as river valleys, cliffs and hillsides, and human-made exposures such as quarries and road cuttings.
How do you find a fossil in a rock?
Look for fossils in sedimentary rock, including sandstone, limestone and shale, preferably where the earth has been cleaved by road cuts, construction sites, rivers or streams. Identify hunting grounds by consulting geologic maps and paleontology websites like myFossil.
Where are you most likely to find fossils?
Why are fossils only found in sedimentary rocks?
Many readers may not realize, however, that fossils only come from sedimentary rocks. Why is that? Fossils are found in sedimentary rock because the conditions of sedimentary rock formation are crucial to fossilization, as igneous and metamorphic rock formation would destroy organisms inside.
Where are most fossils found?
sedimentary rock
Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock. Limestone and sandstone are types of sedimentary rock that commonly have fossils.
Why are most fossils found in sedimentary rocks?
Sedimentary rocks, however, are great at forming fossils because of their process of formation: sediments gradually accumulate, bury any life present, preserve and protect it, and transport it to the future for discovery.
