Scientists have identified a previously unknown species of prehistoric bird, several times heavier than its modern relatives, the chicken, from a single fragment of leg bone found in a cave on the Indonesian island of Flores, the same cave that produced the ancient human relative nicknamed the "hobbit."The extinct bird, named Megapodius rokusi, was identified from a fossilised right leg bone recovered inside Liang Bua cave.

Scientists identify Megapodius rokusi, a giant prehistoric chicken relative weighing an estimated 8.6 pounds, from a fossil found in the same Flores cave that yielded Homo floresiensis.
