The "Sabre-toothed Tigers" appear to be Smilodon, but are anatomically more similar to Machairodus. In addition, Machairodus was extinct by the time this film takes place, and Smilodon never lived in Korea or Siberia. Perhaps these cats are meant to represent homotherium, a descendant of Machairodus and contemporary cousin of Smilodon which lived worldwide during the Ice Age and had shorter teeth (but were famous for Mammoth killing, whereas Smilodon wasn't).
