1. A classification of herbivorous dinosaurs distinguished by their long necks, which includes both their ancestral forms and more evolved species known for large sizes and plant-based diets
2. This term describes a lineage of dinosaurs characterized by elongated bodies and significant variance in size, all sharing a reliance on plant materials and specific skeletal traits
3. A category of dinosaurs that encompasses early and more advanced species noted for their extended necks and plant-eating habits

Etymology: Sauropodomorph is a modern scientific coinage, not an ancient word, and its parts are easy to read once you know the Greek. "Sauros" means lizard and "pous" means foot, the root behind "sauropod", the name given to the long-necked giants such as Brachiosaurus. The suffix "-morph" comes from Greek "morphe", meaning form or shape. Paleontologists built the name by attaching "-morph" to "sauropod" to label the wider group that includes the sauropods and their earlier, smaller relatives. The word was formed in the 20th century, when dinosaur classification was being reorganized around family trees rather than loose physical resemblance. Its usage is technical and it appears mainly in paleontological literature rather than everyday English. The early members of the group were not the giants of the Jurassic; they were lightly built, often bipedal animals from the Late Triassic, which is why the name points to a broad "form" rather than only the enormous sauropods.
