Inland taipan Wombey argued that "Parademansia microlepidotus" belongs to a distinct genus, and this was also the opinion of Harold Cogger. Covacevich, McDowell, Tanner & Mengden (1981) successfully argued, by comparing anatomical features, chromosomes and behaviour of the two species then known as "Oxyuranus scutellatus" (taipan) and "Parademansia microlepidota", that they belonged in a single genus. "Oxyuranus" (1923), the more senior name, was adopted for the combined genus. "Oxyuranus microlepidotus" has been the fierce snake's binomial name since the early 1980s. The generic name, "Oxyuranus", means "oxus" (Greek) "sharp pointed", "oura" (Greek) "tail"; "-anus" (Latin) "belonging to", and refers to the inland
Taipan taipans, with the central ranges taipan being an offshoot of the common ancestor of the inland and coastal taipans. Their diets consist primarily of small mammals, especially rats and bandicoots. Species of this genus possess highly neurotoxic venom with some other toxic constituents that have multiple effects on victims. The venom is known to paralyse the victim's nervous system and clot the blood, which then blocks blood vessels and uses up clotting factors. Members of this genus are considered to be among the most venomous land snakes based on their murine , an indicator of the toxicity on mice. The
