'''''Ramsayia''''' is an extinct genus of giant [[wombat]], weighing around 100&nbsp;kg.<ref>{{Cite book|url=https://books.google.com/books?id=UZLuF1YXYTcC&q=Euryzygoma&pg=PA251|title=Extinctions in Near Time|last=MacPhee|first=R.

The skull superficially resembles that of the giant beavers ''[[Castoroides]]'' and ''[[Trogontherium]].'' The large premaxillary spine suggests it possessed a large fleshy nose. The shape of the skull of ''R. magna'' suggests that it did not engage in burrowing. Cladistic analysis suggests that it is closely related to the other giant wombat genera ''[[Phascolonus]]'' and ''[[Sedophascolomys]].'' Like other giant wombats, its size is thought to have been adaption to feeding on large amounts of low quality vegetation.<ref name=":0">{{Cite journal |last=Louys |first=Julien |last2=Duval |first2=Mathieu |last3=Beck |first3=Robin M.
