I focus on Mesozoic Era paleoenvironments, containing the remains of dinosaurs and other vertebrates. The study of ancient biomes, particularly those of the Cretaceous Period, relates to our emerging understanding of the global response to human-induced climate change. During the past 250 million years, the world was never hotter, sea level was never higher, and atmospheric CO2 was never more abundant than during the Cretaceous Period. The rocks and fossils of this period record these environmental extremes and the resulting biotic response. By understanding paleoecological change during previous episodes of global warming, we enhance our ability to understand current changes related to the ongoing climate crisis.
Another facet of my research involves the discovery and characterization of extinct forms of life. The vast majority of species that have ever lived are extinct and paleontologists thus far have discovered only a tiny fraction of these. With this in mind, a component of my fieldwork is exploratory, in pursuit of contributions to the basic characterization of life on Earth. I have co-authored descriptions of two new dinosaurs (Paralititan and Suzhousaurus), a teleost fish (Bawitius bartheli), a necrocarcinid crab, numerous indeterminate species, and several paratypes.
During five expeditions to southern-most South America, my students and I excavated over 16-tons of fossilized remains from Late Cretaceous deposits. Most of this material pertains to extremely large titanosaurian dinosaurs, representing one or more new species. One new holotype under description represents the most complete skeleton known for a dinosaur in the top class of mass. The analysis of this specimen provides an unprecedented opportunity to study the anatomy, biomechanics, and evolution of some of the largest land creatures ever.
I am also a member of the Bahariya Dinosaur Project, based in the Egyptian Sahara, and collaborate with Hai Lu You, PhD (Chinese Academy of Geological Sciences) and Matthew Lamanna, PhD (Carnegie Museum of Natural History) on the evolution of Cretaceous ornithurine birds from the middle Cretaceous of China. In the laboratory, my students and I have isolated endogenous biomolecules from Paleogene- and Cretaceous-age fossils and are developing geochemical model pathways for the preservation of ancient tissues. Locally, my students and I study the Cretaceous fauna of southern New Jersey. Our recently excavated 65 million year old New Jersey crocodilian, Thoracosaurus neocesariensis, is currently on display in the lobby of Stratton Hall at 32nd & Chestnut streets.
