The giant hutias are an extinct group of large rodents known from fossil and subfossil material in the West Indies. One species is estimated to have weighed 150 kg and been as large as an American Black Bear. This is larger than largest rodent living today, but still much smaller than the largest rodent to have ever lived. These animals may have persisted into historic times and were probably used as a food source by aboriginal humans. All giant hutias are in a single family Heptaxodontidae, which contains no living species. In biology and ecology, extinction is the ceasing of existence of a species or group of species. ...
