Prosaurolophus

before Saurolophus ("before the lizard crest")

• pro · Greek · before
• sauros · Greek · lizard
• lophos · Greek · crest

The name means "before Saurolophus". Barnum Brown chose it because he thought this hadrosaur was an earlier, more primitive relative of Saurolophus, which has a similar solid crest. The name combines the Greek "pro" (before) with the genus name Saurolophus ("lizard crest").
