Canariomys
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.Both species became extinct around the beginning of the 1st Millennium, shortly after the first human settlement of the islands by the Guanches.[1] Genetic evidence indicates that the genus is nested within Arvicanthis, specifically within the African grass rat (A. niloticus) species complex, with an estimated divergence from its mainland relatives around 650,000 years ago.
