The heavy-footed moa (Pachyornis elephantopus) is a species of moa from the family Dinornithidae. This moa was widespread on the South Island only, and its habitat was the lowlands (shrublands, dunelands, grasslands, and forests). It was a ratite and a member of the order Struthioniformes. The Struthioniformes are flightless birds with a sternum without a keel. They also have a distinctive palate. The origin of these birds is becoming clearer as it is now believed that early ancestors of these birds were able to fly and flew to the southern areas in which they have been found. The heavy-footed moa was about 1.8 m tall, and weighed as much as 145 kg. Order: Struthioniformes, Family: Dinornithidae.
