Why are fossils of marine animals found in places where
there are no oceans?
There are places that were once under water in warmer areas where the
materials were deposited and eventually became rocks such as limestone.
Eventually, as tectonic forces moved plates and caused areas to lift up,
these areas ended up elevated far away from where we know reefs develop
today. For example, there are some limestone deposits in Ohio, Indiana and
Illinois which we know must have been deposited in a warm oceanic
environment, and are now in the middle of the continent.
