This is an important look at the development of pterosaur babies development inside the egg to determine if they were able to fly after hatching. When compared with some modern species there is a possibility. However, we still can’t say for sure yet as there are yet more questions that need answering. Modern birds need more time to develop and thus more parental care for growing and learning to fly. Perhaps it was the same for some, but not all pterosaurs?
