Dicynodont Link Re‑dates Dinosaurs

Researchers reexamined Triassic fossils from Tanzania with micro‑CT and identified a new species of the South American dicynodont genus Dinodontosaurus, showing the same genus occurs on both continents. That correlation implies the Tanzanian fossil beds are younger than previously thought, moving candidate earliest dinosaur fossils in Tanzania into parity with South American finds and tightening the timeline for dinosaur origins. — This matters because it revises a headline claim about when and where the first dinosaurs appeared and highlights how museum collections and new imaging methods can overturn long‑standing scientific timelines.
