P\u0159i pr\u016flomov\u00e9m objevu paleontologov\u00e9 v Indii odkryli zkamen\u011bl\u00e9 kosti pat\u0159\u00edc\u00ed jednomu z nejv\u011bt\u0161\u00edch had\u016f, kter\u00fd byl kdy objeven. Ostatky, nazvan\u00e9 Vasuki indicus, byly nalezeny v dole v okrese Kutch ve st\u00e1t\u011b Gud\u017ear\u00e1t v z\u00e1padn\u00ed Indii. Kosti jsou star\u00e9 p\u0159ibli\u017en\u011b 47 milion\u016f let a jsou pozoruhodn\u011b velk\u00e9, m\u011b\u0159\u00ed a\u017e 2,4 palce na d\u00e9lku a 4,3 palce na \u0161\u00ed\u0159ku.<\/p>\n\n
Pomoc\u00ed dvou r\u016fzn\u00fdch metod v\u011bdci odhadli velikost Vasuki indicus. Jedna metoda nazna\u010dila d\u00e9lku mezi 36 a 40 stopami, zat\u00edmco druh\u00e1 p\u0159edpov\u00eddala d\u00e9lku mezi 48 a 50 stopami. Tyto odhady \u0159ad\u00ed Vasuki indicus jako druh\u00e9ho nejv\u011bt\u0161\u00edho zn\u00e1m\u00e9ho hada, p\u0159ekonan\u00e9ho pouze vyhynul\u00fdm Titanoboa, kter\u00fd m\u011b\u0159il p\u0159ibli\u017en\u011b 43 stop.<\/p>\n\n
Vasuki indicus pat\u0159il do vyhynul\u00e9 \u010deledi suchozemsk\u00fdch had\u016f zvan\u00e9 Madtsoiidae. Tito hadi se plazili po r\u016fzn\u00fdch kontinentech, v\u010detn\u011b Madagaskaru, Ji\u017en\u00ed Ameriky, Indie, Afriky, Austr\u00e1lie a Evropy, b\u011bhem pozdn\u00ed k\u0159\u00eddy a pozdn\u00edho pleistoc\u00e9nu. Anal\u00fdza zkamen\u011bl\u00fdch kost\u00ed nazna\u010duje, \u017ee Vasuki indicus m\u011bl pravd\u011bpodobn\u011b \u0161irok\u00e9 a v\u00e1lcovit\u00e9 t\u011blo, podobn\u00e9 modern\u00edm hrozn\u00fd\u0161\u016fm, a mohl ob\u00fdvat suchozemsk\u00e1 nebo polovi\u010dn\u00ed vodn\u00ed prost\u0159ed\u00ed.<\/p>\n\n

Objev Vasuki indicus je v\u00fdznamn\u00fd z n\u011bkolika d\u016fvod\u016f. Poskytuje nov\u00e9 poznatky o rozmanitosti vyhynul\u00e9 megafauny, zejm\u00e9na suchozemsk\u00fdch had\u016f.
