Majorcan giant dormouse

The Majorcan giant dormouse (Hypnomys morpheus) is an extinct animal from Majorca, Spain in Europe. It is considered an example of island gigantism. The closest extant relative is considered to be the genus Eliomys, which includes the garden dormouse. It is believed to have been omnivorous, and may have been terrestrial rather than arboreal. The arrival of humans on the island is believed to have been a major factor in its extinction. H. morpheus was described by the palaeontologist Dorothea Bate in 1919. A 2011 study estimated its body weight as between 173 and 284 g, with a head and body length of 179 mm and a total body length of 295 mm.
