Extinct family of mammals
Thereuodon is a genus of extinct mammal known from the Early Cretaceous of southern England, Morocco and France. The type species, named by Denise Sigogneau-Russell in 1989 for teeth from the earliest Cretaceous Ksar Metlili Formation of Morocco, is Thereuodon dahmani, while the referred species named by Sigogneau-Russell and Paul Ensom for teeth from the Lulworth Formation of England is Thereuodon taraktes. The two species are separated by a break in the cingulum in "T. dahmani", a more obtuse medial crest in "T. taraktes", a duller stylocone in "T. taraktes", a "c" cuspule in "T. dahmani", and a reduced facet A in "T. taraktes". The genus "Thereuodon" is the only taxon in the symmetrodont family Thereuodontidae, which may be closely related to Spalacotheriidae. A tooth referred to "T. cf. taraktes" is known from the Berriasian aged Angeac-Charente bonebed of France.
