Articles relating to the Gondwanatheria, an extinct group of mammaliaforms that lived in the Southern Hemisphere, including Antarctica, during the Upper Cretaceous through the Miocene (and possibly much earlier, if Allostaffia is a member of this group [1]). Until recently, they were known only from isolated teeth, a few lower jaws, two partial skulls and one complete cranium. [2] Because of this fragmentary knowledge, their placement is not clear, although more details have emerged from newer finds and studies. [3]
