Canaanimys is an extinct genus of caviomorph known from the Loreto of Peru.^[1]

Description[]

Canaanimys is known from the holotype MUSM 1890, a right second molar and from some referred teeth including MUSM 1889, MUSM 1891, MUSM 1892, MUSM 1893, MUSM 1894 and MUSM 1895. It was collected in the CTA-27 Locality (or Maquía locality), from the uppermost part of the , dating to the latest Lutetian stage of the late Middle Eocene, about 41 million years ago. It was a tiny rodent as its body mass estimated at approx. 40 g. A cladistic analysis found it to be the basalmost known caviomorph, and one of the oldest (the other being Cachiyacuy from the same locality).^[1]
