Re: *Brachiosaurus* labyrinth paper...
However, his method (actually Preuschoft's)
Yep -- Preuschoft, no later than 1976. <rant>In German, in a ?journal called
(translated) "Essays and speeches of the Nature-Researching Society of
Senckenberg", so it was probably published irregulary. In other words,
hardly anyone can ever have read it.</rant>
depends on what seems like
a very questionable assumption, namely that the habitual posture of an
animal's neck is the one that most nearly equalises the stress exerted
on the intervertebral discs. I can't for the life of me see why this
should be true. If a useful posture entails more stress on
intervertebral joint A than on B, the animal is hardly likely for that
reason to favour a posture in which the stress on B is _increased_ to
match that on A.
Surely the assumption is that the habitual posture should be the one with
minimal stress everywhere? At least that's how I read Christian & Heinrich
To be fair to Christian 2002,
though, it does apply the method to a couple of extant critters
"In the late 40s, it was felt by some academics that Britain
would need 3 or 4 computers, and the US 6 or 7. Unbelievable
but true. Those early computer pioneers certainly were morons"

Obviously they believed computers would only be used as supercomputers. They
just failed to anticipate Moore's Law.
