Oldest Long-Necked Dinosaur Found in Brazil

There's a lot missing from the fossil record when it comes to the earliest dinosaurs. That makes the discovery of not one but three well-preserved skeletons, two of them nearly complete, all the more significant. Even better: The new species they represent, Macrocollum itaquii, is the oldest long-necked dinosaur known. The trio gives us a snapshot of a lineage in transition from small and swift meat-eaters to the mightiest animals ever to walk Earth.
