Hi gang

dinogeorge was talking about the use (or nonuse) of the tails of suaropods
for cooling purposes. While I agree that the cylindrical shape isn't
maximized for cooling, it doesn't mean that it couldn't be used for that
purpose if the shape was developed for something else beforehand. I get lots
of cooling from my head (esp when I used to play soccer) with its marvelous
shinny top. I think that its fairly certain that my head was develped for
some other reason first. I probably do this because I don't have a conical
tail. In addition, Kangoroos lick their wrists to cool themselves, and I
suspect that their wrists were originally meant to attach their hands to
their arms.

Another area: hummingbirds hibernate everynight.
