Species: S. musacchioi (type).
Size: Skull 43 centimetres long. Total body length unknown.
Known locations: Argentina - Bajo Barreal Formation.
Time period: Cenomanian/Turonian of the Cretaceous.
Fossil representation: Partial skull, jaws and first seven cervical (neck) vertebrae.
from a skull and seven neck vertebrae, Sarmientosaurus
is a genus
that lived in South America during the early stages of
the Late Cretaceous. Sarmientosaurus is noted
for having eyes
sockets that were proportionately larger than in other titanosaurs.
Studies of the inner ear area also show that held was likely held
downwards at the end of the neck, suggesting that Sarmientosaurus
specialised more in feeding upon lower growing vegetation.
