Project Summary:

Two new species of hadrosaurine dinosaur were recently collected in the Judith River Formation of northcentral Montana. The goal of this research is to describe the new taxa and place them into ontogenetic and evolutionary context using cranial descriptions and long-bone histology, as well as to study the taphonomy and stratigraphy of these sites to provide environmental context and locate the relative stratigraphic positions of closely related taxa.
