Dinosaur fossils not only have a lot to say about local ecosystems, but also about the arrangement of the world's continents 100 million years ago. Until recently, Elrhazosaurus--the bones of which were discovered in central Africa--was considered to be a species of a similar dinosaur, Valdosaurus, hinting at a land connection between these two continents. The assignment of Elrhazosaurus to its own genus has muddied the waters somewhat, though there's no disputing the kinship between these two bipedal, plant-eating, toddler-sized ornithopods.
