Oxygen-isotope analyses of the eggs show that the dinosaurs drank from a variety of freshwater bodies such as rivers and small evaporative pools, whereas the carbon-isotope values indicate that the reptiles were consuming plants that utilize the C3 photosynthetic pathway, e.g., small palms, shrubs, conifers, etc. Similar analyses of the host limestones suggest that they were deposited in a freshwater environment that provided the niche for large-scale breeding and nesting of the dinosaurs.
