Where were fossils of *Archaeocorvus meadewaldenis* (AMRI) unearthed?
Answer
North-western Queensland, Australia
The fossils identified as *Archaeocorvus meadewaldenis*, representing the earliest known member of the magpie family, were specifically unearthed in north-western Queensland, located on the ancient Australian continent. This discovery provides crucial geographical context, indicating that the ecological niche occupied by smart, adaptable omnivores like corvids was established in this region much earlier than the divergence of the specific magpie genus *Pica* found later elsewhere. This Australian site marks the world's oldest known fossil for this entire avian family.
