Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's fourth largest island (after Greenland, New Guinea, and Borneo), the second-largest island country (after Indonesia), and the 46th largest country overall. Its capital and largest city is Antananarivo.

Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife being endemic. The island has a subtropical to tropical maritime climate. Madagascar was first permanently settled during or before the mid-first millennium AD by Austronesian peoples, presumably arriving on outrigger canoes from present-day Indonesia. These were joined around the ninth century AD by Bantu groups crossing the Mozambique Channel from East Africa. Other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. Consequently, there are 18 or more classified peoples of Madagascar, the most numerous being the Merina of the central highlands.

Until the late 18th century, the island of Madagascar was ruled by a fragmented assortment of shifting sociopolitical alliances. Beginning in the early 19th century, most of it was united and ruled as the Kingdom of Madagascar by a series of Merina nobles. The monarchy was ended in 1897 by the annexation by France, from which Madagascar gained independence in 1960. The country has since undergone four major constitutional periods, termed republics, and has been governed as a constitutional democracy since 1992. Following a political crisis and military coup in 2009, Madagascar underwent a protracted transition towards its fourth and current republic, with constitutional governance being restored in January 2014.

Majungasaurus (/məˌʌŋɡəˈsɔːrəs/; lit.'Mahajanga lizard') is a genus of abelisaurid theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period, making it one of the last-known non-avian dinosaurs that went extinct during the Cretaceous–Paleogene extinction event. The genus contains a single species, Majungasaurus crenatissimus. This dinosaur is also called Majungatholus, a name which is considered a junior synonym of Majungasaurus.

Like other abelisaurids, Majungasaurus was a bipedal predator with a short snout. Although the forelimbs are not completely known, they were very short, while the hind limbs were longer and very stocky. Measuring around 7 m (23 ft) long and weighing more than 1,000 kg (2,200 lb), it can be distinguished from other abelisaurids by its wider skull, the very rough texture and thickened bone on the top of its snout, and the single rounded horn on the roof of its skull, which was originally mistaken for the dome of a pachycephalosaur. It also had more teeth in both upper and lower jaws than most abelisaurids. (Full article...)

The culture of Madagascar reflects the origins of the Malagasy people in Southeast Asia, East Africa and Oceania. The influence of Arabs, Indians, British, French and Chinese settlers is also evident.

The most emblematic musical instrument of Madagascar, the valiha, is a bamboo tube zither carried to the island by early settlers from southern Borneo, and is very similar in form to those found in Indonesia and the Philippines today. Traditional houses in Madagascar are likewise similar to those of southern Borneo in terms of symbolism and construction, featuring a rectangular layout with a peaked roof and central support pillar. Reflecting a widespread veneration of the ancestors, tombs are culturally significant in many regions and tend to be built of more durable material, typically stone, and display more elaborate decoration than the houses of the living.

UA 8699 (University of Antananarivo specimen 8699) is a fossil mammalian tooth from the Cretaceous of Madagascar. A broken lower molar about 3.5 mm (0.14 in) long, it is from the Maastrichtian of the Maevarano Formation in northwestern Madagascar. Details of its crown morphology indicate that it is a boreosphenidan, a member of the group that includes living marsupials and placental mammals. David W. Krause, who first described the tooth in 2001, interpreted it as a marsupial on the basis of five shared characters, but in 2003 Averianov and others noted that all those are shared by zhelestid placentals and favored a close relationship between UA 8699 and the Spanish zhelestid Lainodon. Krause used the tooth as evidence that marsupials were present on the southern continents (Gondwana) as early as the late Cretaceous and Averianov and colleagues proposed that the tooth represented another example of faunal exchange between Africa and Europe at the time.
