The emela-ntouka (Bomitaba or Lingala: "killer of elephants" or "eater of the tops of trees") (Scientific Name: Elephaceratotherium africasimum, Colloquial Name: Emela-ntouka)
is a neodinosaurian cryptid reported from the rainforest swamps and rivers of the Republic of the Congo and the southwest Central African Republic, described as a horned animal, which has been compared to rhinoceroses and ceratopsian dinosaurs. It is frequently synonymised with the older, but now lesser-known, Zambian water rhinoceros, the chipekwe, as well as the ngoubous of Cameroon and the ntambue ya mai of the southern Democratic Republic of the Congo, and with certain reports of forest rhinoceroses.
The emela-ntouka's morphology has been described as well-defined, but perplexing. It is said to be an elephantine, rhinoceros-like amphibian with a large horn on its nose, and a heavy crocodile-like tail. Traditionally, two very different competing theories regarding the emela-ntouka's identity have been held: a large semiaquatic rhinoceros; or, mainly in light of the cryptid's heavy tail, a surviving ceratopsian dinosaur. However, the latter theory is no longer supported by many cryptozoologists, with the emela-ntouka now regarded as a mammal. One ethnic group, the Aka, apply the name mokele-mbembe to the emela-ntouka, a custom which has caused some confusion.
