DescriptionBallusia restoration.png
English: Life restoration of the Early Miocene bear Ballusiass. This restoration are mostly based on 820846, a fossil specimen consisting of a crushed skull, vertebral column, tail and limb bones: it was first described in 1985 as a species of the of the "dawn bear" genus Ursavus, named "Ursavus orientalis",[1] but subsequent studies have placed it into Ballusia, a more recently erected genus which is more basal than Ursavus to modern bears.[2][3]
Ballusiass were about the size of a domestic cat, with body proportions similar to a modern wolverine (Gulo gulo). It was more slender built than modern bears, and might have been insectivorous/omnivorous.[4] The colour pattern used here is a guess, mostly inspired by modern small carnivores such as wolverine (Gulo gulo), european badger (Meles meles), pine marten (Martes martes) and red panda (Ailurus fulgens).
