Definition

Noun: A dromaeosaur is a type of carnivorous, bipedal theropod dinosaur belonging to the family Dromaeosauridae. These dinosaurs were generally small to medium-sized, fast-running predators characterized by a large, sickle-shaped claw on the second toe of each foot, which was likely used for slashing prey. They are closely related to birds and are considered a kind of maniraptor, a group of coelurosaurian dinosaurs that includes birds and their closest extinct relatives.

Usage Examples

• Noun:
  • The dromaeosaur is famous for its large, curved claw.
  • Fossils of the dromaeosaur Velociraptor have been found in Asia.
  • Scientists study the dromaeosaur to understand the evolution of flight in birds.

Advanced Usage

• As a taxonomic group: The term is often used in paleontology to refer to the entire family Dromaeosauridae.
  • Dromaeosaur anatomy provides key evidence for the dinosaur-bird link.
• In popular culture: Often colloquially referred to as "raptors," especially due to their depiction in films.
  • The film's antagonists were based on the dromaeosaur Deinonychus.
