Antarctica was further north (isn't hard to do :-) ) during the Mesozoic, as
documented by geophysics and paleontology. Also, the super-chilled deep
marine waters now present in the oceans are a recent (okay, a Tertiary)
development, cause by the formation of the pyschrospheric circum-Antarctic
currents after the Antarctica-Australia breakup.
