Ischyromys is an extinct genus of rodent from North America. It possessed strong hind limbs with claws on each five toes of its hind feet, like modern rodents. It is believed that Ischyromys was an efficient tree climber like squirrels today. These ancient rodents grew to about two feet (over half a meter) in length, and resembled large mice in appearance. As a result they probably lived in trees like squirrels do today.
