"Giga-Goose: Ancient 500-Pound Bird Roamed Australia"

Researchers have studied fossils of Genyornis newtoni, a 500-pound Ice Age bird that went extinct around 45,000 years ago. New findings from South Australia's Lake Callabonna reveal that this bird, nicknamed the 'Giga-Goose,' had a goose-like bill and adaptations for foraging in water, suggesting it lived in semi-aquatic environments. The study, published in Historical Biology, provides new insights into the bird's morphology and ecological niche, although the exact cause of its extinction remains uncertain.
