Research and Professional Interests:
My primary area of expertise is evolutionary paleobiology, archosaurian reptiles (crocodiles, non-avian and avian dinosaurs (birds), and pterosaurs) in particular. I also have ancillary interests in the evolution of terrestrial oxudercine gobies (mudskippers). The major focus of my research is the form, function, performance, and development of the musculo-skeletal system from which inferences on life history, physiology, biomechanics, and ecology are drawn. This provides new and novel insights into the most important radiations in earth history (e.g. the 85-million year domination of predatory niches at the water-land interface by crocodilians, the evolution of gigantism and diversification of dinosaurs, the evolution of avian flight, the evolution of dental occlusion and diversification in herbivorous reptiles, and the vertebrate conquest of land). I employ phylogenetic principles and methods from several traditional fields of study--including geology, anatomy, mechanical and material science engineering, physiology, ecology, developmental biology, and vertebrate anatomy--to address unique cross-disciplinary paleobiological questions. My general approach to these questions is to conduct extensive testing on extant systems prior to implementation on fossil taxa. I typically collaborate with a diversity of researchers from different fields and research institutions, both domestically and internationally, in China, Mongolia, Germany, Spain, Romania, Canada, England, Australia, and Argentina. In addition, I am the co-director of the Paleo-Arctic Research Consortium and have an active NSF-funded field program in the Early Maastrichtian Prince Creek Formation on Alaska’s North Slope studying the vertebrate fauna to better understand how these animals flourished under extreme environmental conditions at 85 degrees North paleolatitude. I also conduct neontological fieldwork throughout Florida and overseas garnering data on crocodilian feeding biomechanics, and in southern latitudes collecting and studying mudskipper locomotion. Finally, I am a TV presenter and host for documentaries on predatory animals (crocodilians in particular) and dinosaurs, consultant for permanent museum exhibits, and senior scientific advisor for children’s books and travelling animatronics exhibitions on prehistoric animals.
I teach courses on: Human gross Anatomy, Comparative evolutionary vertebrate anatomy, Evolutionary morphology, Herpetology, and the Paleobiology of dinosaurs. In my research program I am currently studying:
1. Means to assess longevity and growth rates in extinct and living reptiles (e.g. dinosaurs, crocodilians, lizards) using skeletal growth markers and the use of these data for inferring heterochronic patterns. These data are further used to reconstruct aspects of ancient population biology and ecology.
Major findings/advancements to date include:
Generating the first mass-age growth curves for dinosaurs
Showing that dinosaurs grew more considerably more rapidly than living reptiles and were lilely endothermic
Revealing that the largest and oldest T. rex (“Sue”) was just 28 years of age
Discovering the means by which dinosaurs attained their iconic gigantism (heterochronic acceleration) using tyrannosaurs as a model system
Making the first survivorship curves for dinosaur populations
- Showing that basal birds such as Archaeopteryx were physiologically just feathered dinosaurs
2. Crocodilian feeding biomechanics through bite-force experimentation.
Major findings/advancements to date include:
- Developing bite force meters allowing the first measurements of crocodilian bite forces throughout development
- Measuring bite forces and tooth pressures in every species of living crocodilian and showing bite force performance is pound for pound the same in any taxon regardless of diet
- Recording world record bite forces of 3,700 pounds and tooth pressure 360,000 pounds per square inch for a 17- foot saltwater crocodile in Australia
- Predicting 23,000 pound bite forces in giant extinct crocodilians
Major findings/advancements to date include:
- Determined dinosaur tooth replacement rates using daily forming von Ebners growth lines (duck-billed dinosaurs [hadrosaursids] wore down and shed their teeth in just 30-50 days and went through 3,300 teeth per year)
- Described the first T. rex bite marks from which their feeding style (puncture and pull) and bite forces were simulated using a mechanical testing frame
- Discovered that the mechanical wear properties of fossil teeth are preserved
- Showed that hadrosaurid and horned-dinosaur (ceratopsians) teeth are histologically and biomechanically more sophisticated than those of herbivorous mammals
- Conducted simulations and empirical wear tests showing how hadrosaurid teeth self-wore to create horse-like grinding surfaces springboarding their ecological diversification
4. Paleo-Arctic Faunal Composition and Paleobiology. I conduct both neontological and paleontological fieldwork and have worked on projects involving extant salmon, mudskippers, bears, and crocodilians and fossil amphibians, reptiles, and mammals. My current field program involves characterizing the vertebrate fauna of the Prince Creek Formation in the Arctic of Alaska and determining how dinosaurs coped with colder climates than they are typically
Major findings/advancements to date include:
- Histological data suggesting the dinosaurs were year-round denizens.
- Discovery that nearly every dinosaur and mammal is new to science suggesting that the community represents a formerly unrecognized Arctic-adapted polar province.
