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]

	Edaphosauridae Sphenacodontia Haptodus garnettensis Palaeohatteria longicaudata Pantelosaurus saxonicus Ianthodon schultzei Cutleria wilmarthi Sphenacodontoidea Therapsida Sphenacodontidae Secodontosaurus obtusidens Cryptovenator hirschbergeri Sphenacodon Ctenospondylus Dimetrodon

Spindler (2016) utilized use of the name Palaeohatteriidae for the clade comprising Palaeohatteria and Pantelosaurus but not Ianthodon.[2]
