Reproduction and Developement

The last few decades have witnessed important discoveries in the field of dinosaur developmental biology and a dramatic change in our perception of how dinosaurs grew and developed. Our research on this topic has centered on the embryonic development, growth, and reproductive characteristics of several groups of dinosaurs. These studies have reported on the discovery of embryos and/or neonates of the long-necked sauropods and the carnivorous theropods (including birds), and they have documented different nesting strategies and behaviors for some of these dinosaurs. Paramount among these investigations has been the discovery and interpretation of Auca Mahuevo, an enormous Late Cretaceous sauropod nesting ground in Patagonia (Argentina) that has yielded significant information about the development and reproductive behavior of titanosaur sauropods.
