Anodontosaurus is an extinct genus of ankylosaurid dinosaurs within the subfamily Ankylosaurinae. It is known from the entire span of the Late Cretaceous Horseshoe Canyon Formation (mid Late Campanian to “middle” Maastrichtian stage, about 72.8-67 Ma ago) of southern Alberta, Canada, and is also known from the Dinosaur Park Formation (75.6 Ma ago). It contains two species, A. lambei and A. inceptus.
