What is "odontopteryx"

Odontopteryx \O`don*top"te*ryx\, n. [NL., fr. Gr. 'odoy`s, 'odo`ntos, a tooth + pte`ryx a wing.] (Paleon.) An extinct Eocene bird having the jaws strongly serrated, or dentated, but destitute of true teeth. It was found near London.

Odontopteryx is a genus of the prehistoric pseudotooth birds or pelagornithids. These were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty.
