Complex species status for extinct moa (Aves: Dinornithiformes) from the genus Euryapteryx.

The exact species status of New Zealand's extinct moa remains unknown. In particular, moa belonging to the genus Euryapteryx have been difficult to classify. We use the DNA barcoding sequence on a range of Euryapteryx samples in an attempt to resolve the species status for this genus. We obtain...
