Fossils-
Fossils are the remains of prehistoric
life and are important because they are left behind in the
sedimentary rock. The fossils are important keys for looking
into the past, knowing about how the life forms existed help
scientist piece together the geological past. They are also
good for setting time tables for other rocks found in different
areas.

Bryan Moynihan term: Normal Fault:
Normal Fault- Normal Faults are faults where the hanging
wall moves down relative to the footwall. They tend to occur
at divergent plate boundaries where the ground is being stretched.(1)
Normal faults often occur in pairs, with one being the main
fault and the other being a smaller conjugate fault.(2) As
you can see with the picture below the line to the right is
the footwall and a normal fault occurred causing the hanging
wall to move down relative the footwall.
