Thereuodon
Extinct family of mammals
From Wikipedia, the free encyclopedia
Thereuodon is a genus of extinct mammal known from the Early Cretaceous of southern England, Morocco and France.[1] 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.[2] A tooth referred to T. cf. taraktes is known from the Berriasian aged Angeac-Charente bonebed of France.[1]
