Taxonomy
The Etruscan bear appears to have originated from Ursus minimus and gave rise to the modern brown bear (Ursus arctos) and the extinct cave bear (Ursus spelaeus).[2] The range of Etruscan bears was mostly limited to continental Europe, with specimens also recovered in the Great Steppe region of Eurasia. Fossil evidence for the Etruscan bear has been recovered in Palestine, Greece,[3] Croatia, and Tuscany, Italy.[4]
Some scientists have proposed that the early, smaller variety of U. etruscus from the middle Villafranchian era is the ancestor of the modern Asian black bear.[5]

Morphology
Similar in size to the brown bears of Europe, it had a full complement of premolars, a trait inherited from the genus Ursavus.
Ecology
Like modern brown bears, Ursus etruscus was likely omnivorous,[6] with some populations possibly relying heavily on fish.[7]
