Hadrosaur
From Memory Alpha, the free Star Trek reference
(Redirected from Parasaurolophus)
The hadrosaur was an Earth dinosaur that lived in the Cretaceous period.
It was the most highly evolved cold-blooded organism to develop from the Eryops and was believed to have vanished when a mass extinction occurred at the end of the Cretaceous period. The hadrosaur was considered potentially to be a direct evolutionary predecessor of the Voth. (VOY: "Distant Origin")
The hologram depicts Parasaurolophus, one of many genera of hadrosaurs.
