Tenerife giant rat

Crusafont Pairó & Petter, 1964
The Tenerife giant rat (Canariomys bravoi) is an extinct species of rodent 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. Radiocarbon dating has placed some of the finds in the late Pleistocene.
Fossilized remains of this animal have been found practically in every part of the island, but 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 (Gallotia goliath). In particular, its bony remains have been discovered in large amounts in the deposit of Buenavista del Norte (in the northwest of Tenerife).
Their fossils date back to the Pliocene and Pleistocene epochs. The first fossils were found by the naturalist Telesforo Bravo, from whom the name of the rodent is derived. Biologists Crusafont-Pairó and Petter first described the giant rat in 1964.
Today, the Museo de la Naturaleza y el Hombre in Santa Cruz de Tenerife exhibits fossil skulls and bones of this animal, as well as faithful reconstructions. Another giant rat of the Canary Islands was Canariomys tamarani.
This species was a big rat of about 1 kg. It had a cranium that reached up to seven centimetres in length. Including the tail, the rat was over 114 centimetres, making it the largest of its family (at least in the Canaries).
