Fossilized teeth from Australia's outback reveal three new marsupial species, filling a 30-million-year gap in their evolutionary history and challenging existing theories about their lineage.

• Rogue teeth found in Australia's outback fill a 30-million-year gap in marsupial evolution
• Three new insect-eating marsupial species from the Keeunamorphia order were identified
• The discovery challenges previous understanding of marsupial lineages and their survival beyond 55 million years ago
