Oryzomys peninsulae, also known as the Lower California rice rat, is a
species of rodent from western Mexico. Restricted to the southern tip of
the Baja California peninsula, it is a member of the genus Oryzomys of
family Cricetidae. Twenty-one specimens of O. peninsulae are known,
caught in 1896 and 1906 at two locations about 13 km (8 mi) apart
along the Río San José, a river in southernmost Baja California Sur.
Río San José no longer exists, having fallen prey to irrigation
projects, and touristic development of its estuary has resulted in
pollution. Biologists working in the area in 1979 and from 1991 to 1993
failed to find O. peninsulae, casting doubt on its continued existence.
Medium in size for its genus, it was first described as a separate
species, but later lumped into other widespread species until it was
reinstated as separate in 2009. It is distinctive in fur color—grayish
brown on the forequarters and reddish brown on the hindquarters—and in
some dimensions of its skull (pictured), with a high braincase, robust
zygomatic arches (cheekbones), and long incisive foramina (perforations
of the palate between the incisors and the molars).
