South
America is known as the cradle of giant dinosaurs, including other
massive sauropods such as Argentinosaurus.
Futalognkosaurus however has
more skeletal material including the vertebrae (cervical and dorsal),
sacrum, ilia, right pubis and ischium and ribs. Unfortunately the
skull, tail and legs are unknown. Despite the lack of this material,
Futalognkosaurus still has the most preserved
parts of any of the
South American groups. This has also allowed for comparison to other
sauropods, with others like Malawisaurus
being
found to be similar.
Futalognkosaurus
acquired its name from the Mapuche words 'futa' (giant) and 'lognko'
(chief) combined with the Greek 'saurus' (lizard).
