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.
A new study using advanced artificial intelligence (AI) has revealed that the asteroid strike that wiped out the dinosaurs 66 million years ago caused only a modest decline in shark and ray species. The findings, published ...

Ceratopsians were horned, beaked dinosaurs that once stomped their way all over North America and Asia during the Late Cretaceous period, about 80 million years ago. Their abundance in the fossil records of these continents, ...
In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% of all species on Earth were wiped out, including the dinosaurs. Among those thought to have perished ...
In the age of dinosaurs—before whales, great whites or the bus-sized megalodon—a monstrous shark prowled the waters off what's now northern Australia, among the sea monsters of the Cretaceous period.
