Further, some characters were duplicated some had only one described state for one, most taxa were scored after presumed relatives.

We report 4,200 misscored cells, over half of them due to typographic and similar accidental errors. Journal of Systematic Palaeontology 5:69–122) recovered, for example, Seymouriamorpha, Diadectomorpha and (in some trees) Caudata as paraphyletic and found the “temnospondyl hypothesis” on the origin of Lissamphibia (TH) to be more parsimonious than the “lepospondyl hypothesis” (LH)-though only, as we show, by one step. The largest published phylogenetic analysis of early limbed vertebrates (Ruta M, Coates MI. Phylogeny of Paleozoic limbed vertebrates reassessed through revision and expansion of the largest published relevant data matrix. Cite this article Marjanović D, Laurin M.
