Vintana sertichi is an early gondwanatherian mammal dating from the Late Cretaceous, approximately 66 million years ago. Scientists found the lone fossil, a skull, on Madagascar's west coast in the Maastrichtian Maevarano Formation.

Vintana is extremely relevant to the understanding of gondwanatheres because it is the first well-preserved skull, as opposed to previous fragments and teeth. Establishing a connection with multituberculates and haramiyidans in the theriiform clade Allotheria, it is a rather unusual animal, either closely associated with the archosaursorEuarchontoglires and Laurasiatheria, possessing massive lateral flanges in its skull whose exact purpose is poorly understood, as well as massive olfactory bulbs. A rather large animal at a weight of 19 pounds (8.74 kg), Vintana also represents another example of a considerably large Mesozoic mammal alongside Adalatherium, another gondwanathere from same formation, this body mass is only exceeded by Repenomamus[1][2][3][4] and Patagomaia.
