Like all major adaptations, sauropod necks probably benefited the animals in
a variety of ways, including all of the following and probably more still
unguessed: increasing foraging range, reducing energy expenditure, looking
out for predators, and long-distance landmark-locating (which would have been
useful in migrations).
