Lydekker's line A line that defines the easternmost extension of oriental animals into the zone of mixing between the Oriental and Australian faunal regions. The corresponding western limit of the zone is known as Wallace's line, and marks the maximum extent of marsupials (Marsupialia) in that direction. It is named after the British naturalist R. Lydekker (1849–1915).
