The new species was three times heavier -- about six kilograms (13 pounds) -- than the biggest rats known to exist today, which are found in the tropical forests of the Philippines and New Guinea.[...]
Researchers found 13 more rat specimens in caves on Timor and other islands, 11 of which are completely new to science.
Aplin said that some of those new species may still be alive today and have simply eluded detection by scientists.
Rodents of unusual size? I don't think they exist.
