The fossil record, for one, shows that warmwater 
faunas have occurred over long stretches of time 
in areas with cool or even cold climates today; 
this is talking about the world in general, not 
just the Gulf of M�xico. In many places warmwater 
faunas are interbedde with coolwater ones, 
indicating that climates warm and cool. And there 
were major glaciations at various times as well, 
in part evidenced by smoother & ice-gouged rocks, 
some of these being hundreds of millions of years 
ago.

At present my boss is working on oxygen isotopes 
in fossil shells and bones; these can be used to 
indicate temperatures and can give a good 
approximation of ice volumes at the times at 
which the animals were living.
