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.
