Predator-prey dynamics are an important evolutionary driver of escalating predation mode and efficiency, and commensurate responses of prey [1-3].

Describes the first skeletal non-avian dinosaur remains found in amber—a 99-million-year-old juvenile tail section with eight vertebrae and 3D chestnut-brown and white plumage. Microscopic imaging reveals primitive, branching barbs and barbules lacking a rigid central shaft, confirming early feather evolution models.

Feathers, not just for the birds? Theropod dinosaurs, thought to be the direct ancestors of birds, sported birdlike feathers. But were they the only feathery dino group? Godefroit et al.
The rise of dinosaurs was a major event in vertebrate history, but the timing of the origin and early diversification of the group remain poorly constrained. Here, we describe Nyasasaurus parringtoni gen. et sp.
The largest dinosaur bone-bed ever unearthed is providing evidence that the dinosaurs were wiped out in catastrophic coastal storms, new findings published this month report.
The sauropod dinosaurs, which included titans such as Brachiosaurus, Diplodocus, and Apatosaurus (once known as Brontosaurus), are well-known for the very long necks they usually sported.
Stanford researchers have aimed high-energy X-ray beams at an Archaeopteryx fossil, identifying key chemicals in the creature's 150-million-year-old bones and wings.
Newly found fossils of a feathered dinosaur suggest that extinct reptiles might have possessed a diversity in plumage types.
Nopcsa interpreted small dinosaur bones discovered on a Transylvanian estate as the remains of dwarfed animals that had once lived on an island.
