Omnivorous dinosaur discovered

Scientists have found fossil remains of an omnivorous dinosaur in Argentina -- a missing link to the carnivores, a researcher said Monday. "It is an omnivore -- in other words it ate everything (plants and meat) -- which is the missing link between carnivorous dinosaurs and giant four-footed herbivores," said Oscar Alcober, also director of the Natural Sciences Museum in San Juan, 1,200 kilometers (745 miles) west of Buenos Aires."
