Palaeoloxodon is an extinct genus of elephant. The genus originated in Africa during the Early Pleistocene, and expanded into Eurasia at the beginning of the Middle Pleistocene. The genus contains the largest known species of elephants, over 4 metres (13 ft) tall at the shoulders and over 13 tonnes (29,000 lb) in weight, representing among the largest land mammals ever, including the African Palaeoloxodon recki, the European straight-tusked elephant and the South Asian Palaeoloxodon namadicus. P. namadicus has been suggested to be the largest known land mammal by some authors based on extrapolation from fragmentary remains, though these estimates are highly speculative. In contrast, the genus also contains many species of dwarf elephants that evolved via insular dwarfism on islands in the Mediterranean, some like Palaeoloxodon falconeri less than 1 metre (3.3 ft) in shoulder height as fully grown adults, making them the smallest elephants known. The genus has a long and complex taxonomic history, and at various times, it has been considered to belong to Loxodonta or Elephas, but today is usually considered a valid and separate genus in its own right.
Stegodon is an extinct genus of proboscidean, related to elephants. It was originally assigned to the family Elephantidae along with modern elephants but is now placed in the extinct family Stegodontidae. Like elephants, Stegodon had teeth with plate-like lophs that are different from those of more primitive proboscideans like gomphotheres and mammutids. Fossils of the genus are known from Africa and across much of Asia, as far southeast as Timor. The oldest fossils of the genus are found in Late Miocene strata in Asia, likely originating from the more archaic Stegolophodon, subsequently migrating into Africa. While the genus became extinct in Africa during the Pliocene, Stegodon persisted in South, Southeast and Eastern Asia into the Late Pleistocene.
Dwarf elephants are prehistoric members of the order Proboscidea which, through the process of allopatric speciation on islands, evolved much smaller body sizes in comparison with their immediate ancestors. Dwarf elephants are an example of insular dwarfism, the phenomenon whereby large terrestrial vertebrates that colonize islands evolve dwarf forms, a phenomenon attributed to adaptation to resource-poor environments and lack of predation and competition.
Għar Dalam[A] is a 144-metre long phreatic tube and cave, or cul-de-sac, located in the outskirts of Birżebbuġa, Malta. The cave contains the bone remains of animals that were stranded and subsequently became extinct in Malta at the end of the Last Glacial Maximum. It has lent its name to the Għar Dalam phase in Maltese prehistory, and is viewed as one of Malta's most important national monuments. Pottery similar to that found in Stentinello was found at Għar Dalam, but lacking details such as stamp decorations.
Apodemus is a genus of Muridae. The name is unrelated to that of the Mus genus, instead being derived from the Greek ἀπό-δημος.
Candiacervus is an extinct genus of deer native to Pleistocene Crete. Due to a lack of other herbivores, the genus underwent an adaptive radiation, filling niches occupied by other taxa on the mainland. Due to the small size of Crete, some species underwent insular dwarfism, the smallest species, C. ropalophorus, stood about 40 centimetres (16 in) at the shoulders when fully grown, while other species were relatively large and comparable in size to mainland deer species. Some species are noted for their peculiar, elongate club-shaped antlers, though other species have more normal antlers.
The Calamian deer, also known as Calamian hog deer, is an endangered species of deer found only in the Calamian Islands of Palawan province in the Philippines. It is one of three species of deer native to the Philippines, the other being the Philippine sambar and the Visayan spotted deer.
Palaeoloxodon namadicus is an extinct species of prehistoric elephant known from the early Middle to Late Pleistocene of the Indian subcontinent, and possibly also elsewhere in Asia. The species grew larger than any living elephant, and some authors have suggested it to have been the largest known land mammal based on extrapolation from fragmentary remains, though these estimates are speculative.
Mammuthus lamarmorai is a species of dwarf mammoth which lived during the late Middle and Late Pleistocene on the island of Sardinia in the Mediterranean. It has been estimated to have had a shoulder height of around 1.4 metres (4.6 ft). Remains have been found across the western part of the island.
The Cypriot pygmy hippopotamus is an extinct species of dwarf hippopotamus that inhabited the island of Cyprus from the Pleistocene until the early Holocene. One the smallest known hippopotamus species, it was comparable in size to the living pygmy hippopotamus though it was more closely related to the common hippopotamus, with its small body size a result of insular dwarfism. It represented one of only two large terrestrial mammals on Cyprus alongside the Cyprus dwarf elephant. The species became extinct around 12,000 years ago following the arrival of humans on Cyprus, and potential evidence of human hunting has been found at the Aetokremnos rockshelter on the southern coast of the island.
Hippopotamus pentlandi is an extinct species of hippopotamus from Sicily, known from the late Middle Pleistocene to early Late Pleistocene. It is the largest of the insular dwarf hippos known from the Pleistocene of the Mediterranean, "at most 20% smaller than the mainland forms", with an estimated body mass of approximately 1100 kg. It is suggested that it arrived in Sicily between 250,000 and 150,000 years ago, probably descending from the modern hippopotamus, with an origin from Hippopotamus antiquus being less likely. In comparison to those species, the muzzle was shorter, the occipital and nasal regions were more developed, the mastoid process was enlarged, and the dental row was shortened, and the condyle of the mandible is low. In comparison to H. amphibius, the orbits are also elevated. It was present in Sicily until at least the latest Middle Pleistocene around 120 kya, and was probably extinct by the beginning of Marine Isotope Stage 4. Contemporaneous species include the dwarf elephant Palaeoloxodon mnaidriensis, the aurochs, red deer, steppe bison, fallow deer, wild boar, brown bear, wolves, red foxes, cave hyena and cave lions. Its diet was likely grazing dominated, similar to that of modern H. amphibius. It is probably ancestral to Hippopotamus melitensis from Malta, which is substantially smaller than H. pentlandi.
Palaeoloxodon cypriotes is an extinct species of dwarf elephant that inhabited the island of Cyprus during the Late Pleistocene. A probable descendant of the large straight-tusked elephant of mainland Europe and West Asia, the species is among the smallest known dwarf elephants, with fully grown individuals having an estimated shoulder height of only 1 metre (3.3 ft). It represented only one of two large animal species on the island alongside the Cypriot pygmy hippopotamus. The species became extinct around 12,000 years ago, around the time humans first colonised Cyprus, and potential evidence of human hunting has been found.
Stegolophodon is an extinct genus of stegodontid proboscideans. It lived during the Miocene epoch in Asia. The earliest fossils are known from the Early Miocene, with one of the oldest fossils being from Japan, estimated to be 17.3 million years old. It is suggested to be the ancestor of Stegodon, and transitional fossils between the two genera known from the Late Miocene of Southeast Asia and Yunnan in South China. Like modern elephants, Stegolophodon developed proal jaw movement, where the lower jaw moves in a back-to-front motion, rather than the oblique chewing motion used by earlier proboscideans, with this development already present by 17.3 million years ago. Members of the genus generally have tetralophodont molars, and retain tusks on the lower jaw. The upper tusks have an enamel band.
The Philippine long-tailed macaque is a subspecies of the crab-eating macaque, known in various Philippine languages as matching/matsing or the more general term unggoy ("monkey"). It is endemic to the Philippine forests and woodlands, but especially in the mangrove forests of western central Philippines— particularly in Palawan, the Visayas, and Mindanao. The names M. f. philippinensis and M. f. philippinenesis have also been used, but arise from orthographical error.
Palaeoloxodon creutzburgi is an extinct species of elephant known from the Middle-Late Pleistocene of Crete. It is a descendant of the large mainland species Palaeoloxodon antiquus. It is known from localities across the island. P. chaniensis from Stylos and in Vamos cave, Chania, west Crete is considered to be a junior synonym of P. creutzburgi. It had undergone insular dwarfism, being approximately 40% of the size of its mainland ancestor, and was around the size of the living Asian elephant. It lived alongside the radiation of Candiacervus deer endemic to the island, the mouse Mus batae-minotaurus, the Cretan otter, and the Cretan shrew.
Mammuthus creticus, or the Cretan dwarf mammoth, is an extinct species of dwarf mammoth endemic to Crete during the Early Pleistocene to early Middle Pleistocene.
Rhagamys is an extinct genus of rodents in the subfamily Murinae, the Old World mice and rats. The genus was established by the Swiss zoologist Charles Immanuel Forsyth Major to accommodate Rhagamys orthodon, which is the only species in the genus. It was endemic to the Mediterranean islands of Corsica and Sardinia, descending from Rhagapodemus, which had colonised the islands around 3.6 million years ago. Its closest living relatives are of the genus Apodemus, which includes the field and wood mice.
Nesorhinus is an extinct genus of rhinoceros from the Pleistocene of Asia. It contains two species, Nesorhinus philippinensis from Luzon, Philippines and Nesorhinus hayasakai from Taiwan.
Kritimys, also known as the Cretan giant rat is an extinct genus of murid rodent that was endemic to the island of Crete during the Early and Middle Pleistocene. There are two known species, K. kiridus from the Early-Mid Pleistocene, and its descendant K. catreus from the Middle Pleistocene. It is suggested to be closely related to and probably derived from Praomys. As with most island rodents, Kritimys was larger than its mainland relatives, with its size increasing over time, with K. catreus estimated to weigh 518 grams (1.142 lb), around 6.7 times the weight of its mainland ancestor, an example of island gigantism. The temporal range of the genus is considered to define the regional Kritimys biozone, during which time there were only two other species of mammal native to the island, a species of dwarf mammoth, Mammuthus creticus and the dwarf hippopotamus Hippopotamus creutzburgi. It became extinct during the late Middle Pleistocene, following the arrival of the Mus bateae-minotaurus lineage to the island, exhibiting a decrease in size shortly before its extinction.
Stegoloxodon is an extinct genus of dwarf elephant known from the Early Pleistocene of Indonesia. It contains two species, S. indonesicus from Java, and S. celebensis from Sulawesi. Its relationship with other elephants is uncertain.
