Ampasambazimba - это горная вершина и субфоссильное участие на Мадагаскаре, недалеко от анализа , ( итази ), наиболее известного за то, что они являются местом остатков вымершего гигантского ленивого лемурского археоиндриса .
Ампасамбазимба расположена на уровне 1036 метров над уровнем моря. [ 3 ] Это было обнаружено в 1902 году месье Рэйбо, колониального администратора в то время. В 1909 году гигантский лемурский археоиндрис был описан Гербертом Ф. Стоящим с использованием фрагментов субфоссила. [ 4 ] [ 5 ] обнаружил полный череп Позже Чарльз Ламбертон , который он затем опубликовал в 1934 году. [ 5 ]
Ампасамбазимба считается одним из самых продуктивных и наиболее известных субфоссильных участков на Мадагаскаре. [ 1 ] Ряд спорадических раскопок были проведены в Ампасабазимбе, в диапазоне 1902 по 1984 год. Раскопки привели к открытию 15 видов лемуроидов, из которых семь вымерли. Раскопки также привели к открытию 13 видов птиц, из которых восемь были вымершими.
History
[edit]Prehistoric
[edit]
Radiocarbon dating suggests lemuroid species were living on Ampasambazimba over 22,000 years ago.[1] The dating also showed that tree specimens had existed over 8,000 years ago.[1] It has been believed that the giant sloth lemur Archaeoindris had been living when humans first set foot on Madagascar at approximately 350 BC.[6] Subfossil evidence suggested that Megaladapis grandidieri was the last extant lemuroid species, with the subfossil sample being dated 900–1040 AD.[1] Birds and eagles, including Stephanoaetus mahery, were also thought to have been living at Ampasambazimba over 5,500 years ago.[7]
Prior to human arrival, Ampasambazimba was thought to have been a more open habitat, rather than a completely forested area. It consisted of a mix of woodlands, bushlands, and savanna.[8]
Discovery
[edit]In 1902, Monsieur Raybaud,[9] a colonial administrator, discovered Ampasambazimba[10] and constructed a report to then-President of France Émile Loubet.[11] This prompted a number of sporadic excavations, ranging from 1902 to 1984. Excavations unearthed an "enormous amount of bone material".[12] 15 lemur species, including Archaeoindris and Megaladapis, were unearthed; seven were extinct.[10][12] 13 bird species, including Stephanoeatus mahery, were also unearthed; eight were extinct.[7][12]
