How do paleontologists find fossils?
The simple answer is that they know where to look! Paleontologists search certain rock types where fossils would likely have been preserved. For example, water-lain strata such as ancient lake beds and river or floodplain deposits often contain fossils. Then the dirty work begins. They examine the ground in search of any bone or plant fragments. Paleontologists often prospect for new remains exposed after the beds have weathered for awhile.
