They were the largest herbivores in their environment, and quickly reached (6 to 10 meters long). All prosauropods had a long neck and small head, forelimbs shorter than the hindlimbs, and a very large thumb claw for defense. They were originally thought to be the ancestors of the [[sauropod]]s, but are now considered by some as a parallel lineage. == Taxonomy == *'''Infraorder Prosauropoda''' **?''[[Yimenosaurus]]'' **''[[Meroktenos]]'' **?''[[Mussaurus]]'' **Family [[Riojasauridae]] ***''[[Eucnemesaurus]]'' ***''[[Riojasaurus]]'' ***Family Plateosauridae ****''[[Plateosaurus]]'' ****''[[Sellosaurus]]'' ****?''[[Unaysaurus]]'' ****Family [[Massospondylidae]] *****?''[[Adeopapposaurus]]'' *****''[[Coloradisaurus]]'' *****''[[Lufengosaurus]]'' *****''[[Massospondylus]]'' *****''[[Yunnanosaurus]]'' *****''[[Jingshanosaurus]]'' [[category:Prosauropods| ]]
