What It Means

Deceptive Lizard

Did You Know?
Apatosaurus’ long neck may have been used to reach large areas of low vegetation, or to poke into strands of trees to get foliage that was otherwise unavailable to the huge, lumbering varieties of sauropods that could not go into the forests because of their size. Alternatively, the long neck may have enabled this sauropod to eat soft-leaved plants that lived in wet areas while standing on firm, dry ground.
