Discovery and Taxonomy
The Malagasy hippopotamus was first described in the mid-19th century by Alfred Grandidier, who unearthed nearly 50 individual hippos from a dried-up swamp near Lake Ranobe, a few miles from the Mozambique Channel. As many as four different species of hippopotamus were subsequently identified by various researchers. In a careful revision of the fossil record of the Malagasy hippos, Solweig Stuenes concluded that there were only two species of hippopotamus which she classified as Hippopotamus lemerlei and Hippopotamus madagascariensis. In 1990, Faure and Guerin discovered a distinct third species of hippo, which they named Hippopotamus laloumena. In a review of Stuenes work, Harris suggested that Hip. madagascariensis had much in common with the extant pygmy hippopotamus of West Africa. Since the extant pygmy hippopotamus was placed in the genus Hexaprotodon, he used the name Hex. madagascariensis. Some taxonomists, however, consider the modern pygmy hippo to belong to the genus Choeropsis, so this species may also be classified as C. madagascariensis.
The fossil record of the Malagasy hippopotamus is extensive. At least seven hippopotamus bones show unequivocal signs of butchery, suggesting that they survived until humans arrived on Madagascar. The evidence of humans butchering the hippos also suggests their extinction may have been, in part, due to humans. Despite the discovery of many fossils, the hippos of Madagascar are not very well studied, perhaps because researchers are interested in some of the more exotic megafauna of Madagascar, such as the giant lemurs and the elephant birds.

Famous quotes containing the words discovery and and/or discovery:
“The new supplants the old. Yet mens minds are stuffed with outworn bunk. Educating the young in the latest findings of authorities and scholars in the social sciences is important. It is equally important to devise ways and means for aiding the middle-aged and old to reexamine hang-over unscientific doctrines and ideas in the light of recent discovery and research.”
—Mary Barnett Gilson (1877?)
“Next to the striking of fire and the discovery of the wheel, the greatest triumph of what we call civilization was the domestication of the human male.”
—Max Lerner (b. 1902)
