> Abstract: New  material of polyglyphanodontine lizards from the Late
> Cretaceous has been found  in various localities in western North America.
> Several
> transversely oriented  teeth representing a new species of Dicothodon were
> recovered from the Turonian  of southern Utah. These specimens necessitate
> reassignment of Polyglyphanodon  bajaensis to Dicothodon (Polyglyphanodon)
> bajaensis.
> >From the Campanian of Utah,  additional teeth and jaw fragments referable
> to
> Manangysaurus saueri have been  recovered and this
> species is reassigned here to Peneteius (Manangysaurus)  saueri. Also, an
> isolated tooth referable to Peneteius has been recovered from  the
> Campanian of
> southern Texas. The results of a phylogenetic analysis support  a
> monophyletic
> grouping of the transversely-toothed taxa with Bicuspidon as the  sister
> taxon
> of Polyglyphanodontini new taxon, which is comprised of  Polyglyphanodon,
> Dicothodon, and
> Peneteius. The phylogenetic analysis also  places ??teiid?? lizards from
> the Cretaceous of Asia and North America in a  monophyletic group,
> Borioteiioidea new taxon, which is the sister taxon to the  Teiioidea
> (Teiidae +
> Gymnophthalmidae). This new hypothesis of the  interrelationships of these
> taxa requires
> the reevaluation of several  characteristics that were previously
> considered
> diagnostic for a  more
> inclusive Teiidae. Another implication of our results is that Teiidae
> (sensu
> stricto) has no demonstrable pre-Tertiary occurrence. It appears that
> Teiioidea and Borioteiioidea diverged from a common ancestor by the Early
> Cretaceous. The Teiioidea entered South America and are currently
> represented by  the
> Teiidae and Gymnophthalmidae, whereas Borioteiioidea radiated throughout
> North
> America with subsequent dispersal to Asia and Europe.
