Miocene pseudotoothed bird

Ron Scarlett described a proximal right humerus found in Middle to Late Miocene (15-8 million-year-old) sediments near the mouth of Waipara River (North Canterbury) as probably that of a pelagornithid. Four years later, Harrison & Walker tentatively assigned the specimen to the Miocene pseudotoothed bird Pelagornis miocaenus.

Pelagornithids (pseudotoothed birds) were gigantic marine birds of uncertain relationships. They had a worldwide distribution between the late Paleocene and the end of the Pliocene (56-3 million years ago). The smallest species were the size of an albatross, and the largest species had wingspans of 5-6 metres.

The Miocene pseudotoothed bird was a large pelagornithid described from the Early and Middle Miocene of France. The only New Zealand specimen (CMNZ AV 24960) is held in Canterbury Museum.
