> >From the Campanian of Utah, additional teeth and jaw fragments referable

> 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

> diagnostic for a more

> 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
> America with subsequent dispersal to Asia and Europe.
