Coryphomys is an extinct genus of rats, known from sub-fossils found on Timor. Species include Coryphomys buhleri and Coryphomys musseri. Archaeological research on East Timor has revealed the bones of rats weighting up to 6 kilograms = 13.2 pounds when adult. They seem to have died out between 1000 and 2000 years ago, perhaps due to large-scale forest clearance for farming.
