Amargasaurus was a sauropod dinosaur that lived in what is now Argentina
from roughly 129 to 122 million years ago, during the Early Cretaceous
epoch. The only known skeleton was discovered in 1984 and is virtually
complete. Amargasaurus cazaui, the only species in the genus, was a
large animal reaching 9 to 10 meters (30 to 33 feet) in length, with two
parallel rows of tall spines down its neck and back. The spines, taller
than in any other known sauropod, probably protruded as solitary
structures supporting a keratinous sheath, and may have been used for
display, combat, or defense. Alternatively, they might have formed a
scaffold supporting a skin sail. A herbivore, Amargasaurus probably fed
at mid-height. Discovered in sedimentary rocks of the La Amarga
Formation, it is most closely related to the Late Jurassic genera
Dicraeosaurus, Brachytrachelopan and Suuwassea. Together, these genera
form the family Dicraeosauridae, with shorter necks and smaller body
sizes than other sauropods.
