Dromaeosaurids are a family of small to medium-sized theropod dinosaurs known for their agility and predatory behavior. They lived during the Late Cretaceous period and are characterized by their long, slender bodies, sharp claws, and a distinctive sickle-shaped claw on each foot. Notable members include Velociraptor and Deinonychus. These dinosaurs were likely feathered, suggesting a close relationship to modern birds. Dromaeosaurids were skilled hunters, often believed to have hunted in packs. Their unique adaptations, such as their keen senses and powerful legs, made them effective predators in their ecosystems.
