Once thought to be a small moa, the adzebill is now thought to be more closely related to cranes. However, like the moa this bird was flightless, only found in New Zealand and is now extinct. Two species are believed to have existed – one on the North Island, the other on the South. The register lists this as the North Island species but this could be incorrect as other documentation suggests they were collected in the South Island. These bones are vertebrae and are in a subfossil state. From the collection of Dr John Teschemaker of Exmouth, donated by his family in 1869. The 3 un-numbered vertebrae may also belong to this accession number.
