ABSTRACT

Theropod teeth are some of the most diagnostic fossils from dinosaur assemblages, with taxonomic utility to the genus or even species level. One hundred and twenty-nine teeth, representing five theropod taxa, have been recovered from eight localities along a 75 km east-west transect in the Judith River Formation of south-central Montana. Unlike the pattern of distribution observed for the Judith River Formation in Alberta, no geographic or temporal differentiation of the theropod faunas seems to have occurred in this formation in south-central Montana.
