The Gran Canaria giant rat (Canariomys tamarani) is an extinct species of rat endemic to the island of Gran Canaria (Canary Islands, Spain).

Contents

This rodent is known from Holocene to pre-Hispanic fossil remains found at several places on the island of Gran Canaria, the youngest of which have been dated to shortly before the beginning of the Common Era. [1] This species was previously listed in the 2000 IUCN Red List of Threatened Species as extinct, but was removed from the list because it is now considered to have gone extinct before 1500 CE.[ citation needed ]

The giant rat was herbivorous and terrestrial, with some digging skills and the ability to climb trees. [2]

The giant rat had an estimated typical head-and-body length of 28.7 cm (11.3 in) and tail length of 20 cm (7.9 in); [2] its average body weight is believed to have been in the 0.75–1.35 kg (26–48 oz) range. [3]

Another giant rat of the Canary Islands was the Tenerife giant rat, Canariomys bravoi. It is believed that the arrival of humans and the introduction of feral dogs led to the extinction of both species. [3]

The Canary Islands, also known informally as the Canaries, are a Spanish region, autonomous community and archipelago in the Atlantic Ocean. At their closest point to the African mainland, they are 100 kilometres west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and are the most populous special territory of the European Union.

<i>Gallotia</i> Genus of lizards

The genus Gallotia are the lacertids of the Canary Islands. This genus consists of a group that has been evolving there ever since the first islands emerged from the sea over 20 million years ago. The endemic species and subspecies of this group have a number of characteristics that make them quite special within their family (Lacertidae); their only close relatives are the sandrunner lizards (Psammodromus) of the western Mediterranean region. Gallotia are characteristic for eating significant quantities of plants, and several lineages are often presented as classic examples for insular gigantism. However, a find of an even larger Gallotia species from the early Miocene of mainland Europe casts doubt on this assumption. Instead the ancestor of all modern Gallotia species of the Canary islands was probably already very large but carnivorous.

The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.

The name giant rat has been applied to various species of large rats and may refer to:

<i>Canariomys</i> Extinct genus of rodents

Canariomys is an extinct genus of rodents that once existed on the islands of Tenerife and Gran Canaria, part of the Canary Islands, Spain. These giant rats could reach a weight of about 1 kg (2.2 lb). They were herbivores; their diet was based on plant materials, probably soft vegetables such as roots, ferns, and berries, but not grass. C. tamarani were considered herbivores, eating everything plant-like except grass with good digging skills. While C. bravoi were considered as a rat character, because of its large size, with an omnivorous diet with good climbing skills. They were one of two groups of rodents native to the archipelago, alongside the lava mouse, which was native to Fuerteventura and Lanzarote.

The cloud rats or cloudrunners are a tribe (Phloeomyini) of arboreal and nocturnal herbivorous rodents endemic to the cloud forests of the Philippines. They belong to the family Muridae and include five genera: Batomys, Carpomys, Crateromys, Musseromys, and Phloeomys. They range in size from as large as 50 cm (20 in) to as small as 74 mm (2.9 in). Cloud rats are threatened by habitat loss and illegal hunting. Several species are endangered or critically endangered.

<i>Gallotia goliath</i> Extinct species of lizard

Gallotia goliath is an extinct giant lizard species from the island of Tenerife of the Canary Islands, Spain. This reptile lived before the arrival of humans and is believed to have grown to at least 0.9 metres (3.0 ft) long. It was described by the German herpetologist Robert Mertens. Fossils of this lizard have been found in volcanic caves, where they often appear with those of other animals, like the Tenerife giant rat.

<i>Hypnomys</i> Extinct genus of giant dormice

Hypnomys, otherwise known as Balearic giant dormice, is an extinct genus of dormouse (Gliridae) in the subfamily Leithiinae. Its species are considered examples of insular gigantism. They were endemic to the Balearic Islands in the western Mediterranean from the Early Pliocene until their extinction around 4,000 years ago. They first appeared in the fossil record on Mallorca during the Early Pliocene, presumably due to the Messinian salinity crisis causing a connection with mainland Europe. They later spread to Menorca, and a possible molar is also known from Ibiza. Hypnomys became extinct during the Holocene after human arrival on the Balearics. They were one of only three native land mammals to the islands at the time of human arrival, alongside the shrew Nesiotites and goat-antelope Myotragus.

<span class="mw-page-title-main">Arvicanthini</span> Tribe of rodents

Arvicanthini is a tribe of muroid rodents in the subfamily Murinae. Almost all recent species in this tribe are or were found in Africa aside from one species, the Indian bush rat, which is found in South Asia and Iran. However, some fossil Golunda species from India and the genus Parapelomys are thought to have also occurred outside Africa, and one species in the fossil genus Saidomys may have also occurred in Afghanistan.
