The Tenerife Giant Rat (Canariomys bravoi) was endemic to the island of Tenerife, the largest of the Canary Islands, Spain. Many remains have been found during archeological digs. Most remains are from the Pleistocene. With help of radiocarbon dating some of the finds are dated from about 12,000 years ago (late Pleistocene) [1]. This species was a big rat of about 1 kg. [2] Including the rat tail was over 45 inches making it the largest of its family (or at least in the Canaries).

Fossil remains of this animal have been found practically in all parts of the island. Especially in deposits in caves or volcanic pipes of the island, where it often appears together with remains of other species such as the giant lizards (Lacerta maxima and Lacerta goliath). Their fossils date back to the Pliocene and Pleistocene, which indicates it lived before the arrival of humans.

Its cranium reached up to 7 centimeters in length; the size of a rabbit. Its bony remains have been discovered especially in the deposit of Buenavista del Norte (in the northwest of Tenerife).

The Giant Rat, as other primitive species of the islands, went extinct due to the actions of human beings guanches and also because of the introduction of the cat. Another Giant Rat of the Canary Islands was the Canariomys tamarani.
