How small is the pterodactyls eggs?

Pterodactyl eggs varied in size depending on the species, but they were generally similar to the size of a modern-day chicken egg, measuring about 4 to 8 inches in length. Some larger pterosaur species may have laid even bigger eggs, but overall, they were relatively small compared to the size of the adult pterosaurs. The eggs were often elongated and had a hard shell, providing protection during development.
