Phylogeny
[edit]The cladogram shown below follows Rieppel (1998)'sphylogenetic analysisof nothosaurids (bold terminal taxa contain living species).[2]Most of these relations are still considered correct today,[4]but despite Rieppel (1998)'s referral ofCeresiosaurusandSilvestrosaurustoLariosaurus,some authors still consider them separate and many additional species have been named since this analysis.[5]
A species levelphylogenetic analysisof Nothosauridae was performed by Liuet al.(2014), and included all known valid species of the family apart fromLariosaurus stensioi(type ofMicronothosaurus),Nothosaurus cymatosauroides,andCeresiosaurus lanzi.The resultant topology is similar to the one obtained in Rieppel (1998) if the new additions are ignored, however this analysis found bothLariosaurusandNothosaurusto bepolyphyleticin regard to each-other and all other genera of the family, making a systematic revision of these two genera necessary. Below, their results are shown with type species of named nothosaurid genera noted.[6]
