Are champosaurs smaller than their mesozoic ansestors?

Champosaurs, which lived during the late Mesozoic era, are generally considered to be smaller than some of their earlier ancestors from the Mesozoic period. While early Mesozoic reptiles, such as some large dinosaurs and marine reptiles, could reach significant sizes, champosaurs evolved to be more streamlined and adapted to their specific environments, resulting in relatively smaller body sizes. However, size can vary significantly among different species within both groups.
