Caiuajara Nest

We know today that pterosaurs had leathery shell eggs that probably were buried to incubate. The babies were highly precocious, hatching already with the body proportions (except the head) very close to those of the adults and fully developed wings. This suggests that they were independent and could fly soon after hatching, not being cared by their parents.

On the other hand, several bones of individuals of different ages of the pterosaur Caiuajara dobruskii were discovered together, suggesting a life in colony. So, in the scene is illustrated an adult helping the babies to hatch, digging out the eggs - but the parental care would stop there.

The appearance of the baby Caiuajara is based not only on the younger individuals found in the "cluster" of this species fossils, but also on Nemicolopterus, which has a good chance of being a very young representative (almost newborn) of the tapejarid Sinopterus.
