Megalampris keyesi is an extinct Opah from the late Oligocene of New Zealand about 26 million years ago. It was recovered from the Otekaike Limestone in North Otago, by a team from the University of Otago. Its spectacular remains, mostly caudal skeleton, are on display in the Otago Museum, Dunedin, New Zealand. Comparison with the skeleton of living Lampris species suggest that it was around 4 meters in length.
