Sakamena

Sakamena dia vohitra iray akaikin'i Betroka izay ao amin'ny faritra Anosy any Madagasikara.

Izy ihany koa dia anrana azo avy amin'ny sosona ara-jeolojika misy vatolampy sedimantera tamin'ny vanim-potoana Permian izay nahitana fôsily maro momba ny biby manana hazon-damosina, anisan'izany ny Triadobatrachus (ny lissamphibian voalohany ^[1] ), Claudiosaurus, iray amin'ireo biby mandady an-drano voalohany, ^[2] ary ny Coelurosauravus, ny biby mandady mivelatra voalohany. ^[3] ^[4] ^[5]

Ny Sosona Sakamena dia sosona vatolampy sedimantera niforona nandritra ny vanim-potoana Permian (eo amin'ny 299 ka hatramin'ny 252 tapitrisa taona lasa izay) sy ny fiandohan'ny Triasika. Ahitana fasika, vato tanimanga ary vatokely izy io. Zava-dehibe eo amin'ny fikarohana ara-tsiansa ity sosona ity satria nahitana fôsily maro an'ny zavamananaina fahiny.

Sakamena anisan'ny anaran'ny toeram-pitrandrahana arintany izay eo akaikin'ny toeram-pitrandrahana arintany ao Sakoa . Samy eo ambany fanombanana sy fampandrosoana ataon'ny Madagascar Consolidated Mining, sampan'ny Red Island Minerals, orinasa naorin'i Sam Malin, ny toeram-pitrandrahana arintany Sakamena sy Sakoa. Anisan'ireo toeram-pitrandrahana arintany hafa mifanila amin'ny faritr'i Sakamena ny toeram-pitrandrahana Ianapera, Imaloto ary Vohibory.
