One day, 195-million years ago, a mother dinosaur laid a clutch of six eggs. Inside the eggs, the tiny embryos grew to the point of hatching. One dinosaur chipped its way out of its egg, hatching into a harsh environment, which was growing drier with time. The tiny reptile was helpless, with no teeth, and depended on its parents to find it food, give it warmth and nurture it.

Erythrosuchus africanus was 4m to 5m long and built like a deep-bodied crocodile. Its tall, relatively lightly built narrow head consisted mainly of huge jaws, each armed with a row of vicious teeth, finally serrated like steak knives.
