This is indeed quite interesting, because neck length is, aside from
the obvious implications for feeding volume, an important factor for
defense behaviour. All stegosaur necks are long enough to "check six"
(look backwards) by lateral flexion, but this means a large dead space
on the other side of the body. if there is only one predator, fine. If
there are two or more...... och! A very long neck, however, allows
checking six by extension, reducing the dead space to what's hidden
behind the osteoderms.
