Шаблон:Short description Шаблон:Automatic taxobox
Heptaxodontidae, rarely called giant hutia, is an extinct family of large rodents known from fossil and subfossil material found in the West Indies. One species, Amblyrhiza inundata, is estimated to have weighed between Шаблон:Convert, reaching the weight of an eastern gorilla. This is twice as large as the capybara, the largest rodent living today, but still much smaller than Josephoartigasia monesi, the largest rodent known. These animals were probably used as a food source by the pre-Columbian peoples of the Caribbean.
Heptaxodontidae contains no living species and the grouping seems to be paraphyletic[1] and arbitrary, however. One of the smaller species, Quemisia gravis, may have survived as late as when the Spanish began to colonize the Caribbean.[2]
Despite the vernacular name, heptaxodontids are not closely related to the extant hutias of the family Echimyidae. Heptaxodontids are thought to be more closely related to the chinchillas.[3]
