Best answer: What are the best rocks to find fossils in?

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.

What rocks do you find fossils in?

Most fossils “hide out” in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.

Which type of rock is very rich in fossils?

Fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone. Earth contains three types of rocks: metamorphic, igneous and sedimentary.

How do you know if a rock has a fossil in it?

How can you tell if a fossil is older or younger?

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
