Macrochelys temminckii Troost, 1835

A keselyűteknős (Macrochelys temminckii) a hüllők (Reptilia) osztályába, a teknősök (Testudines) rendjébe, a nyakrejtő teknősök (Cryptodira) alrendjébe, az Eucryptodira alrendágba, a Polycryptodira kládba és az aligátorteknős-félék (Chelydridae) családjába tartozó faj. Tudományos nevét Coenraad Jacob Temminck holland zoológusról kapta. Magyar nevét a német „Geierschildkröte” elnevezés után kapta, mely szó szerint keselyűteknőst jelent.
