 It had been found a few months earlier in Ocucaje District of Ica Province, Peru.According to paleontologist Mario Urbina, who discovered the specimen, and his colleagues Rodolfo Salas, Ken Campbell and Daniel T. Ksepka, the Ocucaje skull is the best-preserved pelagornithid cranium known as of 2009.Unlike the true teeth of Mesozoic birds like "Archaeopteryx" or "Aberratiodontus", the pseudoteeth of the Pelagornithidae do not seem to have had serrated or otherwise specialized cutting edges, and were useful to hold prey for swallowing whole rather than to tear bits off it.
