Note that they are explictly dealing with opsithotony (the extreme **dorsal**
hyperextension of the neck and tail). This is distinct from pleurothotony
(lateral curvature), which is not uncommon in long-necked fossils of animals
which likely were not endotherms (pachypleurosaurs, plesiosaurs, hyphalosaurid
Grimly, the authors discuss that this posture can occur in humans... Ick.
