Great hopping mouse

The great hopping mouse (Notomys robustus), also called the broad-cheeked hopping mouse, is an extinct species of rodent native to Australia. It is known only from skulls found in owl pellets in the Flinders Ranges of South Australia, and some of those pellets also held bones of the introduced house mouse, which suggests that it survived into historic times, possibly the second half of the nineteenth century. From the skull it appears to have been relatively large, perhaps a little bigger than the extinct hopping mouse Notomys amplus, and the deposits suggest it preferred clay rather than sandy soils. It was formally described in 2008 and the Mammal Diversity Database lists it as extinct.
