Branta thessaliensis

Branta thessaliensis is a prehistoric species of black goose known from fossils found in Greece. It is among the earliest known members of its genus. Described in 2006, it was of similar size to the Canada goose. It is known from a humerus bone, which differs form the living species by a wider distal end of the diaphysis, a dorsal condyle that is more rounded in dorsal view and more prominent compared to the ventral condyle in distal view, and a deeper humerotricipital sulcus in distal view.
