The hadrosaur was a genus of Earth dinosaur that lived in the Cretaceous period.
It was the most highly evolved cold-blooded organism to develop from the Eryops known to Humans, and was believed to have vanished when a mass extinction occurred at the end of the Cretaceous period.
The hadrosaur was considered to potentially be a direct evolutionary predecessor of the Voth. (VOY: "Distant Origin", "Friendship One").
The hologram depicts Parasaurolophus, one of many genera of hadrosaurs.
