Turkey-sized dinosaur from Australia preserved in an ancient log-jam. The partial skeleton of a new species of turkey-sized herbivorous dinosaur has been discovered in 113-million-year-old rocks in southeastern Australia. The fossilized tail and foot bones give new insight into the diversity of small, bipedal herbivorous dinosaurs called ornithopods that roamed the great rift valley that once existed between Australia and Antarctica.
