|In the documentary|
In the early Jurassic segment, a pack of Coelophysis (identified as Syntarsus) is seen hunting an Anchisaurus. One gets hurt and maybe killed in the process. The pack chases the herd of Anchisaurus and corners one of them. But just as they prepare for the kill, a Dilophosaurus is seen stopping the hunt. The Coelophysis run off. Later, when the predators are eating the carcass, another Dilophosaurus chases them off.
- Anchisaurus is shown to be larger than Megapnosaurus but in real life it was the quite the opposite. This is because the Anchisaurus shown on the program was based on a larger animal named Ammosaurus, which was considered to be synonymous for some time with the former until it was proven to be its own genus.
- The narrator said Megapnosaurus is related to Dilophosaurus as a ceratosaurid but Megapnosaurus is a coelophysid and Dilophosaurus is a dilophosaurid and both groups aren't related at all with ceratosaurs.
- Megapnosaurus is actually a species of Coelophysis.
- Megapnosaurus' hands couldn't pivot without breaking them.
- Megapnosaurus may have had feathers, but it's still debated.
