Dinosaurs, as a scientific topic, encompass a diverse clade of archosaurian reptiles (primarily Dinosauria) that dominated terrestrial ecosystems during most of the Mesozoic Era and are central to research in vertebrate evolution, functional morphology, macroecology, and extinction dynamics. Study of dinosaurs integrates skeletal anatomy, phylogenetics, bone histology, biomechanics, ichnology, and paleoenvironmental reconstruction to investigate growth rates, locomotor strategies, trophic networks, and responses to climatic and tectonic changes. Modern research also emphasizes the dinosaur–bird transition, including the evolution of feathers, flight-related adaptations, and metabolic physiology, as well as patterns of diversification and selectivity associated with the end-Cretaceous mass extinction.
Argentinian researchers have described a Carnian theropod with features previously thought to belong only to much later neotheropods, indicating greater early dinosaur diversity than expected as well as a possible climate-related ...
Imaging technology has revolutionized paleontology, allowing scientists to study fossils that are buried deep in the rock or too small to handle. Two recent studies I was involved with show some of the technology's potential, ...
