Điểm khác biệt chính
- 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.
Did You Know?
Dilophosaurus was about 2.3x longer than Coelophysis.
Dilophosaurus weighed roughly 20x more than Coelophysis.
Both Coelophysis and Dilophosaurus were carnivores.
Coelophysis lived during the Triassic Late while Dilophosaurus lived during the Jurassic Early, separated by roughly 0 million years.
Coelophysis was discovered 65 years earlier, in 1889.
Both belong to the Theropoda clade, making them relatively close relatives.
