New Ruben et al. paper

["John R. Hutchinson" <jrhutch@socrates.berkeley.edu>]

Hi folks--

        This just in:

Ruben, J.A., T.D. Jones, and N.R. Geist. 1998. Respiratory physiology of
the dinosaurs. BioEssays 20:852-859.

Advocates ectothermy for dinosaurs and basal birds but "these data are not
necessarily inconsistent with current models of active lifestyles of
dinosaurs."  Will be review for most people, with some slight changes from
earlier papers, but curiously no mention of hepatic pistons or adaptive
valleys.

If you have web access to BioEssays (John Wiley & Sons, Inc.) you can
download it thru the net.
