You missed "...body-weight classes *up* *to* *198* *lbs* is..." This means that the authors found that for *larger* weights the relationship broke down! In short a human is about the largest animal to which the .67 power ratio applies! Boy is extending it to Sauropods completely out of line! -- Sarima (Stanley Friesen) UUCP: {ttidca|ihnp4|sdcrdcf|quad1|nrcvax|bellcore|logico}!psivax!friesen ARPA: ttidca!psivax!friesen@rand-unix.arpa Brought to you by Super Global Mega Corp .com
