Rhinoceros is a genus comprising one-horned rhinoceroses. This scientific name was proposed by Swedish taxonomist Carl Linnaeus in 1758. [1] The genus contains two species, the Indian rhinoceros (Rhinoceros unicornis) and the Javan rhinoceros (Rhinoceros sondaicus). Although both members are threatened, the Javan rhinoceros is one of the most endangered large mammals in the world with only 60 individuals surviving in Java (Indonesia). The word 'rhinoceros' means "nose-horn" in Ancient Greek.[ clarification needed ]
The genus name Rhinoceros comes from the Ancient Greek words ῥινο- (rhino-), meaning "of the nose" and κέρας (kerás), meaning "horn". [2] [3]
The genus Rhinoceros comprises:
The earliest remains of the genus are known from the Late Miocene, represented by remains such as an indeterminate species found in deposits in Myanmar dating to around 8-9 million years ago. [9]
The species "Rhinoceros" philippinensis from the early Middle Pleistocene of the Philippines and "Rhinoceros" sinensis hayasakai from the Early-Middle Pleistocene of Taiwan have been transferred to Nesorhinus, which appears to be closely related to Rhinoceros. [10] While Rhinoceros fusuiensisYan et al. 2014 [11] from the Early Pleistocene of South China has been transferred to Dicerorhinus. [10] [12]
