Deinonychus Dinosaur Answer Key

• Approximately 3.4 meters (11 feet) in length.
• Estimated weight around 70 kilograms (150 pounds).
• Lived during the Early Cretaceous period, approximately 115-108 million years ago.
• Primarily carnivorous, feeding on smaller dinosaurs and other animals.
• Possessed sharp, serrated teeth suited for slicing flesh.
• Estimated arm length approximately 0.8 meters (2.6 feet).
• Possessed a large, retractable claw on the second toe of each foot.
• The large curved claw was likely used for slashing prey.
• Classified as a theropod dinosaur, part of the dromaeosaurid group.
• First discovered in the Morrison Formation of Montana.
• Lived during the Early Cretaceous.
• First described in 1969 by John Ostrom.
• Distinguishing features include: large, curved claw on the foot and relatively large brain size compared to other theropods.
• Closely related to Velociraptor.
• Evidence suggesting a predatory lifestyle includes the structure of claws, teeth, and overall body design, suggesting speed and agility.
• The skull structure was slender, suggesting a preference for tearing flesh rather than crushing bone.
• Hypotheses include both solitary hunting and pack hunting, based on fossil evidence and comparisons to modern animals.
• Limited evidence currently exists for Deinonychus pack hunting, though close proximity of fossils may suggest some collaborative strategies within the group.
• Limited information on the precise social structure; solitary or small family groups are possible, but data is scarce.
• Likely had a running speed capable of pursuing prey.
• Likely found in forests or woodlands, based on the depositional environment of the fossils.
• Juvenile Deinonychus would have had smaller body size, proportionately larger head, a less developed claw, and less robust proportions than a fully grown adult.
• The brain size of Deinonychus was relatively large compared to other theropods of similar size, suggesting higher intelligence, important for complex hunting.
• The understanding of Deinonychus has evolved from a simple carnivore to a more intelligent, potentially pack-hunting dinosaur.

Deinonychus Study Notes

General Facts

• Deinonychus was a small to medium-sized theropod dinosaur.
• It lived during the Early Cretaceous period.
• It was a carnivorous predator.
• It was relatively intelligent compared to other theropods.

Physical Characteristics

• Deinonychus had a slender build.
• It had long legs and arms.
• Its most striking feature was a large, retractable claw on the second toe of each foot, which was likely used for slashing prey.

Predatory Habits

• Deinonychus likely hunted in packs, relying on speed and agility to bring down prey.
• It had a keen sense of smell and potentially excellent eyesight.
• The structure of its teeth suggested a diet of meat.

Evolutionary Relationships

• Deinonychus was a member of the Dromaeosauridae family of theropods.
• It is closely related to other famous theropods like Velociraptor.

Fossil Evidence

• Deinonychus fossils have been found in the western United States.
• The discovery of these fossils helped paleontologists understand the behavior and characteristics of this dinosaur better.
