       Lagerpeton is a very primitive dinosauromorph that lived in South America during the early Triassic.‭ ‬So primitive is Lagerpeton that it is easily among the most basal dinosauromorphs that we currently know about.‭ ‬Several features can be observed in the known Lagerpeton material including neural spins on the dorsal vertebrae that are slanting slightly forwards,‭ ‬a common feature seen in animals that spend a lot of time actually hopping about.‭ ‬The foot bones are also structured in such a way to aid a hopping movement.
       Lagerpeton was very small and lightly built,‭ ‬almost certainly relying upon its senses as well as quick reflexes and speed and agility to stay out of the jaws of predators such as rauisuchians.
