I used prairie and savannah simply as examples of environments in which
deposition very seldom occurs. I don't care whether there were or weren't such
during the Mesozoic; if there weren't, there were certainly other kinds of
environments in which deposition very seldom occurred. The point is that a
large fraction of the earth at any time is >not< a depositional environment,
and consequently a large fraction of the earth's biome at any epoch will never
have a chance to become part of the fossil record.
