Poteva pesare fino a otto chili ed era alto come un canguro: il tacchino gigante, grande fino a quattro volte gli esemplari di oggi, avrebbe popolato anticamente l’Australia. Si tratta di una specie, finora sconosciuta, scoperta grazie all’analisi dei fossili provenienti da diverse località del paese.
Lo studio, condotto dai ricercatori della Flinders University di Adelaide, ha rivelato cinque nuove specie di volatili estinti. Questi megapodi vivevano nel pleistocene, un’epoca compresa fra 2,5 milioni e 11'000 anni fa.
A quei tempi, la megafauna australiana era particolarmente ricca e annoverava, tra gli altri animali, il diprotodonte, il leone marsupiale e il plerocoptodonte, un canguro preistorico gigante.
