Henkelotherium is an extinct genus of mammal from the Late Jurassic (Kimmeridgian) Camadas de Guimarota, in Portugal.[1] It differs from most other paurodontids in having more postcanine teeth.

Paleobiology[]

Primitive characters of Henkelotherium (e.g. asymmetric condyles of the femur) indicate that this species had a mode of locomotion similar to tree shrews and opossums. The small size of Henkelotherium and elongated tail made it suited to an arboreal lifestyle and capable of climbing trees, a notion supported by the paleoecological reconstruction of the Guimarota ecosystem indicating a densely vegetated environment.[2]
