The table above includes "R. tarandus caboti" (Labrador caribou), "R. tarandus osborni" (Osborn's caribou – from British Columbia) and "R. tarandus terraenovae" (Newfoundland caribou). Based on a review in 1961, these were considered invalid and included in "R. tarandus caribou", but some recent authorities have considered them all valid, even suggesting that they are quite distinct. An analysis of mtDNA in 2005 found differences between the caribou from Newfoundland, Labrador, southwestern Canada and southeastern Canada, but maintained all in "R. tarandus caribou".
