Etymology
the term 'hadrosaur' is a modern scientific latin construction from the late 19th century, directly combining greek roots. the first element, 'hadros' (thick, bulky), refers to the animal's characteristically robust and sturdy build, particularly noticeable in its vertebrae and limb bones. the second element, 'sauros' (lizard), is a standard suffix used in dinosaur nomenclature. thus, the name literally translates to "bulky lizard," a fitting description for these large, heavily-built herbivores known for their distinctive duck-billed snouts.
Analysis
Structure: hadro (thick, bulky) + saur (lizard)
hadro originates from greek 'hadros', meaning thick, bulky, or stout. saur originates from greek 'sauros', meaning lizard.
