Heptaxodon obliquus 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.

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

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