Hippopotamus Antiquus
''Hippopotamus antiquus'', sometimes called the European hippopotamus, is an extinct species of ''Hippopotamus'' that ranged across Europe during the Early and Middle Pleistocene. Chronology In Italy, the first appearance of the taxon is during the late Early Pleistocene, around 1.2 Ma, remains from Coste San Giacomo, suggested to date to around 2 Ma, have an uncertain stratigraphic context. ''H. antiquus'' first became widespread north of the Alps around 1.1 to 1 million years ago. The youngest confirmed remains of the taxon date to MIS 15, (621–563,000 years ago), but there are possibly later records dating to MIS 11 (424,000 to 374,000 years ago). Later records of ''Hippopotamus'' in continental Europe beginning in MIS 13 (~524,000-474,000 years ago), are believed to belong to the modern hippopotamus (''Hippopotamus amphibius'').

Mammal Genera
There are currently 1,258 genera, 156 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being ''Handbook of the Mammals of the World'' series and ''Mammal Species of the World''.

Hippopotamuses
The hippopotamus ( ; : hippopotamuses or hippopotami; ''Hippopotamus amphibius''), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (''Choeropsis liberiensis'' or ''Hexaprotodon liberiensis''). Its name comes from the ancient Greek for "river horse" (). Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average for bull ...

Hippopotamus Sirensis
''Hippopotamus gorgops'' is an extinct species of hippopotamus. It first appeared in Africa during the late Pliocene, and eventually migrated into Europe (where its fossils were first discovered) during the early Pleistocene. It became extinct during the Middle Pleistocene. Fossil records found at Ubeidiya, Israel suggested that they migrated out of Africa around 1.6 million years ago. Some have speculated that ''H. gorgops'' and '' H. behemoth'' are actually the same species given their similar sizes and where they have been found. Taxonomy With an estimated length of , a shoulder height of , and a weight of 3,900-4,500 kg (8,600-9,900 lb), ''H. gorgops'' was larger than its living relative, ''H. amphibius''. Another feature setting it apart from ''H. amphibius'' was the placement of its eyes. Modern hippos have eyes placed high on the skull, but ''H. gorgops'' had eyestalk In anatomy, an eyestalk (sometimes spelled eye stalk and also known as an ommatophore) is a protrusio ...

Hippopotamus Pentlandi
''Hippopotamus pentlandi'' is an extinct hippopotamus from Sicily. It arrived during the Pleistocene. It is the largest of the insular dwarf hippos known from the Pleistocene of the Mediterranean The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western Europe, Western and Southern Europe and Anatolia, on the south by North Africa ..., "at most 20% smaller than the mainland forms".

''Hippopotamus melitensis'' is an extinct hippopotamus from Malta. It arrived after the Messinian salinity crisisHunt, Christopher O., Schembri, Patrick J.Quaternary Environments and Biogeography of the Maltese Islands, page 31, access in 13/03/2016 and lived during the Pleistocene. The absence of predators, and limited food supplies led to the dwarfing of the hippos. The majority of findings of this species are from Għar Dalam, a cave on Malta famous for its Pleistocene fossil deposits.

Hippopotamus Laloumena
''Hippopotamus laloumena'' is an extinct species of hippopotamus from Pleistocene and Holocene Madagascar, making it the oldest of Malagasy hippopotamus. ''H. laloumena'' was much larger than other Malagasy hippopotamus, but was still somewhat smaller than the common hippopotamus (''H. amphibius''). However, little is known about the species because it was identified with only a lower jaw and limb bones. It was described in 1990 by French palaeontologists M. Faure and Guerin, the fossils recovered from a site near Mananjary on the east coast of Madagascar. The species name derives from Malagasy ' "hippopotamus". Radiocarbon dating of ''H. laloumena'' remains returned dates both before definitive human occupation of Madagascar (2364-2212 BP), and after European contact (1670-1950 and 1639-1945 AD). However, the latter were taken from a skull of dubious provenance and importation from mainland Africa cannot be excluded. Nevertheless, ethnographic data collected in Belo sur Mer ...
