Phylogeny

Rhomaleosauridae is a

phylogenetic analyses. Some of these are recovered as basal rhomaleosaurids in certain analyses, or alternatively outside Rhomaleosauridae in more basal positions within Plesiosauria.^[4]^[2]^[3]^[1] The following two cladograms are simplified after two recent analyses, showing only the relationships within Rhomaleosauridae, and some other relevant basal

taxa whose position within the family is highly uncertain.
