An almost complete skeleton of Phoberomys, discovered in Venezuela in 2000, has enabled researchers to reconstruct its size and probable lifestyle. It was 3 m long, with an additional 1.5 m tail, and probably weighed around 700 kilograms, making it the largest known rodent.

Phoberomyspattersoni is being described as the largest rodent that ever lived.
Phoberomyspattersoni lived during a time when South America was isolated from the rest of the world.
Sanchez-Villagra said the closest living relative to Phoberomyspattersoni is probably the pacarana, a slow-moving rodent that can grow to 15 kilograms and lives in the tropical forest of the western Amazon River basin.
