Anosy
Anosy is one of the 22 regions of Madagascar. It is located in the southeast of the country, on the eastern side of what was once the Toliara Province. The name ''Anosy'' means "island(s)" in Malagasy. Due to a strategic sea route running along its coast, Anosy had been an important crossroads for the Malagasy, Muslims, and Europeans. In the mid-1600s, it was the location of the first French colonial settlement in the Indian Ocean. The region was part of the Imerina Kingdom for much of the 1800s and part of the French colony of Madagascar from the late 1800s to 1960. Its exports have included human slaves (shipped to the Mascarene Islands and the United States in the 1700s), live cattle (exported to Réunion for almost 300 years), sisal, natural rubber, rosy periwinkle, graphite, uranothorianite, lobster, sapphires, and ilmenite. Due to its biodiversity and unique Wildlife of Madagascar, wildlife, efforts commenced in the 1980s to promote Environmental protection, environmen ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triadobatrachus
''Triadobatrachus'' is an extinct genus of salientian frog-like amphibians, including only one known species, ''Triadobatrachus massinoti''. It is the oldest member of the frog lineage known, and an excellent example of a transitional fossil. It lived during the Early Triassic about 250 million years ago, in what is now Madagascar. ''Triadobatrachus'' was long, and still retained many primitive characteristics, such as possessing at least 26 vertebrae, where modern frogs have only four to nine. At least 10 of these vertebrae formed a short tail, which the animal may have retained as an adult. It probably swam by kicking its hind legs, although it could not jump, as most modern frogs can. Its skull resembled that of modern frogs, consisting of a latticework of thin bones separated by large openings. This creature, or a relative, evolved eventually into modern frogs, the earliest example of which is ''Prosalirus'', millions of years later in the Early Jurassic. It was first disc ...

Claudiosaurus
''Claudiosaurus'' (''claudus'' is Latin for 'lameness' and ''saurus'' means 'lizard') is an extinct genus of diapsid reptiles from the Permian Sakamena Formation of the Morondava Basin, Madagascar. The pattern of the vertebrate, girle, and limbs indicates that ''Claudiosaurus'' and ''Thadeosaurus'' share a common ancestor. History and discovery ''Claudiosaurus'' is known from the Sakamena Formation of Madagascar. ''Claudiosaurus'' is found from the Late Permian. Although a paper mentions that they have been also found in Early Triassic deposits of Madagascar, citation does not mention that ''Claudiosaurus'' is from Triassic. Biology and description ''Claudiosaurus'' was one of the first members of the Neodiapsida, a group of reptiles containing diapsids more derived than the primitive Araeoscelidia. It had a relatively long body and neck, reaching on overall length of about . It is presumed to have been partially oceanic, living its life in a way similar to the modern marine ...

Coelurosauravus
''Coelurosauravus'' (meaning "hollow lizard grandfather") is a genus of basal diapsid reptiles, known from the Late Permian of Madagascar. Like other members of the family Weigeltisauridae, members of this genus possessed long, rod-like ossifications projecting outwards from the body. These bony rods were not extensions of the ribs but were instead newly developed bones derived from the skin of the animal, a feature unique to weigeltisaurids. It is believed that during life, these structures formed folding wings used for gliding flight, similar to living gliding ''Draco'' lizards. ''Coelurosauravus'' is solely known from the type species, ''C. elivensis'', which was named by Jean Piveteau in 1926 based on fossils from the Lower Sakamena Formation of Madagascar. The species ''Weigeltisaurus jaekeli'' from Europe was formerly considered a species of ''Coelurosauravus'', but is now considered distinct. History of discovery The only known specimens of ''Coelurosauravus'' were coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sakoa
Sakoa is a region of southwestern Madagascar characterised by Madagascar spiny thickets, dry spiny forest and known particularly for its coal fields, the highest quality of which is the Sakoa field. There are a number of license holders on the field. The vast majority of licenses of commercial value are held by Madagascar Consolidated Mining, a subsidiary of Red Island Minerals, founded by Sam Malin, which is appraising and developing the resources of the field. Pan African Mining holds a considerable number of licenses on the periphery of the field. Other coal fields adjacent to the Sakoa region include the Ianapera, Imaloto, Sakamena and Vohibory fields.
