	Well, you still didn't pick up the whole of what they were
saying. 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!
