Meet Tanyka: 275-Million-Year-Old 'Living Fossil' with Sideways Teeth Found in Brazil

• Tanyka amnicola, a 275-million-year-old creature with a twisted jaw and sideways teeth, discovered in Brazil.
• Considered a 'living fossil' even in its own time, it lived during the Permian period, millions of years before dinosaurs.
• Its unique jaw had teeth pointing sideways and denticles for a grinding mechanism, suggesting it crushed or scraped food.
• Fossils were found in ancient lake and river beds in what was once the supercontinent Gondwana.
• Jason Pardo, lead author from the Field Museum, highlights Tanyka's ancient lineage and unusual nature.
