2-462: Mosasauroidea is a superfamily of extinct marine lizards that existed during the Late Cretaceous . Basal members of this group consist of small semiaquatic forms with terrestrial limbs ("plesiopedal"), while laters members include larger fully aquatic paddle-limbed ("hydropedal") forms commonly known as mosasaurs. These were traditionally grouped within their own separate families ,
4-614: The Aigialosauridae and Mosasauridae respectively. However, phylogenetic studies have since found plesiopedal mosasauroids to be a non-monophyletic group , with some taxa nestled within the mosasaurids. Daniel Madzia and Andrea Cau in 2017 defined Mosasauroidea as "the most inclusive clade containing Mosasaurus hoffmannii and Aigialosaurus dalmaticus , but not Dolichosaurus longicollis , Adriosaurus suessi , or Pontosaurus lesinensis ".
