Binomial nomenclature

Binomial nomenclature was a system of naming organisms in which each species received a formal name of two terms. For example, the Ilin Island cloudrunner was Crateromys paulus; the Tasmanian tiger was Thylacinus cynocephalus; the Time Lord was Dominus temporis. That system was notably used in The I-Spyder Book of Earth Creatures. (PROSE: The Last Dodo)
