Hi, Why to quote some sensationalist TV show and not check the internet? One radiocarbon date of Malagasy hippo was from the period of European colonization. And thats it. Survival until today is very unlikely - even people in remote villages in Madagascar have mobile phones and would understand the value of passing the news, if they would catch a live hippo or a giant lemur.
Jurek7 , 24 Nov A chronology for late prehistoric Madagascar. Some taxonomists, however, consider the modern pygmy hippo to belong to the genus Choeropsis, so this species may also be classified as C. Like the modern pygmy hippopotamus, the Malagasy pygmy hippo had eyes on the side of its head rather than high orbits and teeth of the common hippopotamus.
The Malagasy pygmy hippo was similarly less aquatic, with many of its fossils found in the forested highlands of Madagascar. Fossils of both the Malagasy pygmy hippopotamus and H. 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 due to humans. Despite the discovery of many fossils, the hippos of Madagascar are not very well studied.
Evolving into Oblivion When humans first arrived on Madagascar, there were at least 50 lemur species living on the island, the largest of which rivaled the body mass of a male gorilla or orangutan. Not one of the 33 lemur species that still survive on the island is as large as the smallest of the lemurs that disappeared from Madagascar during the past several millennia.
Along with the giant lemurs, Madagascar was populated by other megafauna that have also since vanished. There were huge tortoises, giant predatory raptors, and pygmy hippopotamuses.
There were gigantic flightless birds called elephant birds. These birds were larger than any other birds - living or extinct. They were heavier than the famous foot-tall moas of New Zealand. The eggs of elephant birds could hold the fluid contents of about chicken eggs! There were no cats or dogs on Madagascar; rather there were strange primitive carnivores mongooses, civets, and cryptoprocts , including one that weighed more than 10 kilograms. Madagascar's unusual endemism makes it one of the world's top conservation priorities.
But its endemic plants and animals continue to suffer from practices such as slash-and-burn agriculture and the harvesting of woody plants for charcoal and timber. Grasses are often deliberately burned to stimulate the growth of fresh blades to feed the cattle.
Wild animals are sometimes also hunted. Because of the tremendous endemicity and wealth of plant and animal species on Madagascar, conservationists believe that forest destruction here may have a greater negative impact on global biodiversity than anywhere else on earth. Subfossil Finds Cave, marsh, and stream sites have yielded the bones of animals that lived on the great island prior to colonization by humans and during the past two millennia.
These subfossil sites, so-called because the bones are too fresh to have become fossilized, provide some direct evidence of the history of the long and slow decimation of Madagascar's wildlife following the arrival of humans. Recent explorations of some of these subfossil sites by a team from Duke University North Carolina and associated scientists from the University of Massachusetts, Amherst; the State University of New York at Stony Brook, and the University of Madagascar in Antananarivo have added enormously to our knowledge of the anatomy and adaptations of Madagascar's paleofauna.
These scientists have explored, among other sites, the kilometers of caves at the Ankarana mountains in northern Madagascar, and a pit called Ankilitelo that descends almost feet deep in southwestern Madagascar.
