RE: Polar sauropods

[bchoo@cyllene.uwa.edu.au (B. Choo)]

These are the polar sauropods that I know of:

Rhoetosaurus brownei (?Bajocian eastern Australia)
        Estimated paleolatitude: 65-56 deg.S

Unnamed sauropod (Campanian-Maastrichtian New Zealand)
        Estimated paleolatidude: 55 deg.S
        O-isotope studies suggest a water temp of 14.3 C.
        By this time NZ was well separated from the rest of Gondwana =
        migration was not an option during the winter.

And if you include prosauropods: The chumps who had the honor of getting
        preserved alongside Cryolophosaurus.
        Estimated paleolatitude: 61 deg.S
