In this presentation, we analyzed the evolutiona and biogeography of the Gondwanatheria. As a corollary, we propose that Gondwanatheria are a vicariant sister group of the Laurasian Multituberculata, whose common ancestor was pangeic during the Triassic, and possibly the early Jurassic, i.e., before the rupture of Pangea and the consequent differentiation of Laurasia in the northern hemisphere, and Gondwana in the southern one.
