Magyarosaurus is a genus of dwarf sauropod dinosaur from late Cretaceous Period (early to late Maastrichtian) in Romania. It is one of the smallest-known adult sauropods, measuring only six meters in length. The type and only species is Magyarosaurus dacus. It has been found to be a close relative of Rapetosaurus in the family Saltasauridae in the sauropod clade Titanosauria in a 2005 study of the titanosaurs by Kristina Curry Rogers.
Maguarosaurus appear when a herd is moving by a lake, with one pair accidentally scaring off Pod. They make another brief appearance being killed by dwarf Tarascosaurs. One later appears as a carcass being fed on by a pack of Tarascosaurs and later Pod.
