The cladogram below shows the phylogenetic positions of Palaeohatteria and Pantelosaurus phylogenetic position among other sphenacodonts following Fröbisch et al. (2011).[5]
Spindler (2016) utilized use of the name Palaeohatteriidae for the clade comprising Palaeohatteria and Pantelosaurus but not Ianthodon.[2]
