The first gondwannan taeniolabidid (unrelated lineages would later arrive by sea), Alicantotherium rigobelli is part of the laurasian radiation of these large herbivores in the Paleocene, the rare example that strayed southwards. Although it is seldomly bigger than Taeniolabis taoensis itself (lready a fairly large animal), it seems to be more closely related to Late Paleocene titans from North America and Europe, likely shrinking in size both to to its tropical residence as well as competition from established herbivore groups; this mirrors in some ways South American pantodonts from our own timeline. It was semi-aquatic, a lifestyle already common among taeniolabidids and probably reinforced here due to a lack of competition in the water and too much competition on land. Still, it wasn't quite as aquatic as latter taeniolabidids would become and seems to have been pretty gracile, likely foraging mostly along the shore on herbs, shrubs and horsetails and retreating to the water during heat or danger. Of the northern invaders, it is the most comon fossil find due to its large size and semi-aquatic habits, though not quite as common as giant gondwanatheres and Baroauchenia canifacis.
