Thomasia is a mammaliform from the Haramiyidae that is part of a lineage either unrelated to or a paraphyletic parent to multituberculates[1] from the Early Jurassic period.
Only Thomasia'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.[2][3]
