主な相違点
- Utahraptor (5.5 m, ~500 kg) was roughly 7× heavier than Deinonychus (3.4 m, ~73 kg).
- Both were dromaeosaurids with large sickle-shaped toe claws, but Utahraptor's claw reached 22 cm — among the largest of any known raptor.
- Deinonychus's discovery in 1969 sparked the Dinosaur Renaissance by suggesting dinosaurs were warm-blooded and active; Utahraptor was described in 1993.
- Deinonychus lived in the Early Cretaceous of Montana; Utahraptor in the Early Cretaceous of Utah — they may have overlapped geographically.
- Utahraptor is the closest real-world match to the oversized Jurassic Park Velociraptors; Deinonychus was the actual scientific inspiration for those depictions.
