Maip
is a genus of megaraptorid
dinosaur that lived in South America during
the Late Cretaceous, and going by the size of the fossil bones,
potentially one of the largest megaraptorid dinosaurs so far
discovered. The describing authors of Maip also
considered the
presence of potential attachment points of ligaments upon the ribs.
These might indicate a more avian type of respiratory system as
opposed to the classical reptilian system.
