Definitions

1. A group of large, plant-eating dinosaurs distinguished by their elongated necks that thrived in the Late Triassic to Early Jurassic periods, representing an evolutionary stage between smaller species and the larger sauropods
2. These prehistoric reptiles, known for their substantial size and grazing adaptations, existed during the Late Triassic to Early Jurassic eras, showcasing a pivotal evolutionary transition from smaller dinosaurs to more massive sauropods
3. A type of early dinosaur with a long neck and plant-eating habits that lived in the Late Triassic to Early Jurassic periods and is a precursor to sauropods

Etymology: This group's name was built from Greek, and its parts show how it was defined. "Pro-" means "before," and "sauros" means "lizard," so the name reads roughly as "before lizard-foot." The final element, "pod," comes from Greek "pous," meaning foot. That root is related to English "foot" and to words like "podium" and "octopus." The name points forward to the sauropods, whose name means "lizard-foot." The prefix marks these animals as the earlier relatives of that later group, so the name describes a place in an evolutionary sequence rather than a feature of the animals themselves.
