The evolution of intraspecific variation, growth, and body size in early theropod dinosaurs
… of maturity. The growth patterns of the earliest dinosaurs (230–190 million years ago), in particular the morphological changes undergone during the life history of an individual (i.e., ontogeny) is poorly understood. To tackle this problem, I studied the changes undergone during growth of two …

The Refutation of Bird Evolution by a Study of Feathered Dromaeosaurs as a Created Kind
Secular science seeks to use a group of feathered dinosaurs known as dromaeosaurs as proof of the evolution of birds. Species evolution is not true and feathered dromaeosaurs are misclassified as dinosaurs when they are in fact neither birds nor dinosaurs but a separate animal group as first …

The Rise of Modern Avian Flight: Wing Movement and Joint Mobility Within Ornithurae
… their macroevolutionary transition from dinosaurs to birds during the Mesozoic Era. Thus, Mesozoic fossils offer us a unique opportunity to study the evolution of avian flight. The origin of many bird-like characteristics (e.g., feathers, a toothless beak, small body size) among non-avian …

The Phylogeny of Basal Coelurosaurian Theropods (Archosauria: Dinosauria) and Patterns of Morphological Evolution during the Dinosaur-Bird Transition
Theropod dinosaurs are an iconic and familiar group of extinct species that include predators such as Tyrannosaurus and Velociraptor, as well as an array of other Mesozoic taxa. Carnivorous theropods are the evolutionary ancestors of birds, and the evolutionary transition between theropods and …

Locomotor Ontogeny and the Evolution of Avian Flight
<p>Understanding the origins of organismal diversity is one of biology's most enduring quests. Many authors have posited that modularity, or the developmental decoupling of body parts into discrete functional units, facilitates adaptive radiation by allowing body parts to become independently and …
