Seriously. Apatosaurus is just nuts.
May 13, 2008
Pursuant to a comment I just made on the previous post, here is cervical 8 of YPM 1980, the holotype of Brontosaurus excelsus, now of course known as Apatosaurus excelsus, in anterior and left lateral views, scanned from plate 12 of Ostrom and McIntosh 1966. Look on my cervicals, ye mighty, and despair.
You see? I wasn’t kidding. This thing is beyond crazy. The dorsoventral height of its parapophyses alone exceeds that of the centrum and neural spine together. What the heck was it doing with that thing? Seriously. It makes no mechanical sense whatsoever. To the best of my knowledge no-one has ever even advanced a hypothesis about those honkin’ great cervical ribs … and I am not about to break that streak.
