In Depth

       Named from a skull and seven neck vertebrae,‭ ‬Sarmientosaurus is a‭ ‬genus of titanosaur 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.
