Thereuodon

Thereuodon is a genus of extinct mammal known from the Early Cretaceous of southern England and Morocco. The type species, named by Denise Sigogneau-Russell in 1989 for teeth from the earliest Cretaceous deposits 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 obsute 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.
