The plate-toothed giant hutia (Elasmodontomys obliquus) is an extinct species of rodent in the family Heptaxodontidae. It is the only species within the genus Elasmodontomys. It was found in Puerto Rico.[1]

Description

The rodent is thought to have weighed 13 kilograms (29 lb) and survived for at least 2000 years after humans colonised Puerto Rico.[2]

Taxonomy

Despite being described as a "giant hutia", it has recently been recovered as a member of the Chinchilloidea.[3]
