Stirtodon is an extinct genus of monotreme mammal from the Late Cretaceous (Cenomanian) Griman Creek Formation of Australia. The genus contains a single species, S. elizabethae, known from a large isolated premolar. Stirtodon may be the largest toothed monotreme discovered.[1][2] Several other monotremes are known from the Griman Creek Formation, including Dharragarra, Kollikodon, Opalios, Parvopalus, and Steropodon.[3]
