Apatosaurus laid some of the largest eggs of any dinosaur.

How many eggs do Apatosaurus lay?

The eggs of large, long- necked, sauropod dinosaurs like Apatosaurus have been found in small clutches of about 10, and unlikely received parental care.

How big was an Apatosaurus egg?

Apatosaurus, like other sauropods, hatched from enormous eggs up to a 1 foot (30 cm) wide. Sauropod eggs have been found in a linear pattern and not in nests; presumably the eggs were laid as the animal was walking. It is thought that sauropods did not take care of their eggs .
