Palaeohatteriidae^[1] is an extinct family of basal sphenacodonts known from the Early Permian period (Asselian-Sakmarian stages) of Saxony, Germany.^[2] Two genera are known: Palaeohatteria^[3] and Pantelosaurus.^[4]

Classification

The cladogram below shows the phylogenetic positions of Palaeohatteria and Pantelosaurus phylogenetic position among other sphenacodonts following Fröbisch et al. (2011).^[5]
