Strange reptile fossil puzzles scientists
A 200-million-year-old reptile is rewriting the rulebooks on how four-legged animals conquered the world.
Newly discovered fossils suggest Drepanosaurus had huge hooked claws to dig insects from bark, much like today's anteaters in the forests of Central and South America.
Scientists say the creature defies the convention on how reptiles evolved and flourished.
