Thuliadanta
Thuliadanta is an extinct genus of ceratomorph perissodactyl closely related to modern tapirs that is known from the early Eocene Margaret Formation of Arctic Canada (Nunavut and Northwest Territories). Paleogeographic significance. "Thuliadenta" is known from the highest northern latitudinal region of any extinct tapiroid, indicating a possible North American origin for Tapiroidea. Judging from the use of the mountain tapir as an analogue, "Thuliadanta" may have been a year-round inhabitant in the mild temperate lowland forests of the Eocene High Arctic.
