Subfamily Polyglyphanodontinae Estes, 1983 Genus Bicuspidon Nydam and Cifelli, 2002

Type species: Bicuspidon numerosus Nydam and Cifelli, 2002 (Mussentuchit Member of Cedar Mountain Formation, Albian –Cenomanian boundary, Emery County, Utah) .

Remarks.— Nydam and Cifelli (2002) recognized that Bicuspidon can be a Polyglyphanodontinae and indicates arguments to consider this relationship. However, the lack of cranial material, the presence of active polyphyodonty in Bicuspidon and the frail phylogenetic results prevent for the moment, the confident assignment to this subfamily. Nevertheless, Bicuspidon and Polyglyphanodon sternbergi may be closely related together and the dental morphology in Bicuspidon might be the morphological and temporal antecedent of Polyglyphanodon sternbergi . We refer to the article of Nydam and Cifelli (2002) for more explanations about the relationships of the genus Bicuspidon . We consider the genus Bicuspidon as a member of Polyglyphanodontinae in the present paper.
