Etymology: Ouranosaurus is a modern scientific coinage, built from Greek rather than handed down from ancient writers. Its second element is "sauros," Greek for "lizard," and its first is "ouranos," which in Greek usually means "sky" or "heaven." The name is often glossed as "brave lizard," but the connection to "brave" is uncertain, so the sky sense is the safer reading. The name suits the animal's most striking feature. Its back bore a tall sail formed by long spines projecting from the vertebrae, probably supported by skin. Scientists have debated what the sail was for, with proposals including display, temperature regulation, and attracting mates, though none has been proven.
