Anomalopteryx is an extinct bird genus known colloquially as the lesser moa, little bush moa, or bush moa. It stood more than 1.3 metres (4.3 ft) tall and weighed 30 kilograms (66 lb). It inhabited much of the North Island and small sections of the South Island of New Zealand. Its habitat was lowland conifer, broad-leafed, and Southern beech forests. It is monotypic with the only species discovered is Anomalopteryx didiformis. It is also the smallest known species of moa, weighing barely 30kg and standing less than a metre tall.
Researchers used a new form of DNA sequencing called high-throughput sequencing to determine the little bush moas nuclear genome.
