What is "haramiya"

Haramiya is a mammaliform that is a lineage either unrelated or a paraphyletic parent to multituberculates from the Mesozoic era.

Only Haramiya's teeth and skull have been found; judging from these it has been constructed as a 12 cm (5 in) creature with a resemblance to modern voles. It is presumed to have fed on the leaves of tree ferns, as it had broad cheek teeth for crushing tough vegetable food.
