The phylogenetic placement of other main groups of fossil sea reptiles – the sauropterygians and the ichthyosaurs, which evolved in the early Triassic and in the Middle Triassic respectively – is more controversial. Different authors linked these groups either to lepidosauromorphs or to archosauromorphs, and ichthyosaurs were also argued to be diapsids that did not belong to the least inclusive clade containing lepidosauromorphs and archosauromorphs. The therapsids came under increasing pressure from the dinosaurs in the
