Polyglyphanodon is an extinct genus of Polyglyphanodontid lizard containing the species P. sternbergi[1] from the Maastrichtian aged North Horn Formation of Utah. The species is known from several mostly complete and partial skeletons. It is distinguished by its transversely orientated interlocking teeth, which suggest a herbivorous diet [2]
