主要差异
- Dilophosaurus (7 m, ~400 kg) was much larger than Coelophysis (3 m, ~20 kg).
- Dilophosaurus had two distinctive parallel bony crests on its skull; Coelophysis had a plain, slender skull.
- Both lived in the Early Jurassic–Late Triassic of North America and were among the earliest large theropods.
- Dilophosaurus had a notch in its upper jaw (kinked jaw) of uncertain function; Coelophysis had a uniform, unkinked jaw.
- Jurassic Park depicted Dilophosaurus as spitting venom — there is no fossil evidence for this ability.
