Paleollanosaurus is an extinct genus of sphenodontian reptile that lived during the Late Triassic. The type species P. fraseri was described from a jaw fragment found in West Texas in North America.[1] Remains have also been reported from Switzerland.[2] It is generally considered a basal sphenodontian.
