The labyrinthodont was 359-237 million years ago, lystrosaurus was 298.9-257.9 million years ago, and the duck billed dinosaur was 69 million years ago. That makes the labyrinthodont older.
A duck billed dinosaur is called a Hadrosaurid. They were the first dinosaur family to be identified in North America.

Tyrannosaurus is a carnivore. Stegosaurus is considered an armored dinosaur, although its plates were probably minimally effective as armor. Trachodon was a hadrosaur, or duck billed dinosaur. Thus, the incorrect pairing is horned dinosaur and Diplodocus. Diplodocus didn't have any horns.
Hadrosaurids or duck-billed dinosaurs are members of the family Hadrosauridae, and include ornithopods such as Edmontosaurus and Parasaurolophus.
