Extinct genus of marsupials

Ramsayia Temporal range: Pliocene–Late Pleistocene PreꞒ Ꞓ O S D C P T J K Pg N Ramsayia magna Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Infraclass: Marsupialia Order: Diprotodontia Family: Vombatidae Genus: †Ramsayia Tate, 1951 Species †R. lemleyi †R. magna

***Ramsayia*** is an extinct genus of giant [wombat](/source/Wombat), weighing around 100 kg.[1] *Ramsayia* is known from two species, *Ramsayia lemleyi* from the [Pliocene](/source/Pliocene) of Queensland,[2] and *Ramsayia magna* from the Pliocene to [Late Pleistocene](/source/Quaternary_extinction_event) of Queensland and New South Wales. The skull superficially resembles that of the giant beavers *[Castoroides](/source/Castoroides)* and *[Trogontherium](/source/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](/source/Phascolonus)* and *[Sedophascolomys](/source/Sedophascolomys).* Like other giant wombats, its size is thought to have been adaption to feeding on large amounts of low quality vegetation.[3] The only certain date of *Ramsayia magna* dates to the early Late Pleistocene, around 80,000 years ago, making the timing of its extinction uncertain.[3]
