It's worth noting that southern France and Iberia at that point were an
island, probably somewhat larger than Madagascar. Buffetaut thinks
Gargantuavis occupied a niche similar to the "ostrich dinosaurs" which
lived on the major continents at the time, but were not present in France.
All they have studied at the moment is the pelvis and sacrum, but when I
talked to him (for a report in New Scientist) he said they may have more
bones. He also says the pelvis shows no signs of being closely related to
later flightless birds of comparable size; presumably Gargantuavis went out
with the dinosaurs at the end of the Cretaceous, if it survived that long.
