prosauropod

Prosauropods were a group of herbivorous dinosaurs that lived during the Late Triassic and Early Jurassic periods. They are considered probable ancestors of the larger sauropods, like the famous "brontosaur" types.12

Prosauropods were not particularly large, typically ranging from less than 2 meters (7 feet) to about 8 meters (26 feet) in length. Their remains are among the most common dinosaur fossils found from the Triassic period, discovered across various continents.1

These dinosaurs had a generally stocky build with a small head and a long neck. Their teeth were leaf-shaped, suited for chopping plants. Prosauropods could likely move on both two and four legs, as their forelimbs were shorter than their hind limbs, and their anatomy suggests they could adopt a bipedal stance.1
