About a dozen teeth of a large flat-headed (hadrosaurine) ornithopod are present in the collections. AMNH 8525 consists of a crown (30 mm. long) making an obtuse angle of about 120 degrees with the fang (fig. 8U, V). The teeth are similar in size and morphology to each other and appear to belong to a single species. The crown is diamond-shaped with a bluntly rounded apex. A distinct medial keel
