Cyprus dwarf elephant
The Cyprus dwarf elephant (''Palaeoloxodon cypriotes'') is an extinct species of elephant related to the living Asian elephant. It was among the only mammals on Cyprus before human arrived, and it is thought the Cyprus dwarf elephant came during the last Ice Age. They were only about 1 meter (40 inches) in height. Their small size is thought to be a response to limited resources experienced by their ancestors. Extinction for the Cyprus dwarf elephant came around 11,000 BC.
== Features ==
Cyprus dwarf elephants were part of the prehistoric group of elephants who lived on islands during the Pleistocene epoch. Some other related species of elephants during this time were the genera ''Mammuthus'', ''Elephas'', and ''Stegodon''; the genus ''Mammuthus'' includes the Woolly Mammoth, the genus ''Elephas'' includes the modern elephants, and the genus ''Stegodon'' includes offsets of genus ''Mammuthus''.
Believed to be descended from the straight-tusked elephant, this much smaller species inhabited Cyprus and some other Mediterranean islands after the Messinian salinity crisis, during the Late Pleistocene. Its estimated body weight was only some 200 kilogrammes, a weight reduction of 98% from its ancestors which weighed about 10 tonnes. Their molars however were about 40% of the size of the mainland straight-tusked elephants. The factors responsible for the dwarfing of island mammals are thought to include the reduction in available food, predation and competition. The Cyprus dwarf elephant roamed the world at least until 11,000 BC.
