Pterodactylidae
Pterodactylus isn't known from any adult specimens. However, based on the size and development levels of the many juvenile Pterodactylus that have been found, paleontologists estimate that Pterodactylus had a wingspan of about 5 feet. it has small bodies
Pterodactylus and Stegosaurus probably mostly ignored each other. Pterodactylus was far too small to hunt Stegosaurus, and Stegosaurus eggs probably had a shell too thick for a Pterodactylus to break it.
Pterodactylus had no armor whatsoever. In the case of an attack by a predator, Pterodactylus would have flown away to escape.
Pterodactylus adults probably grew to have a wingspan of about 5 feet. No fossils of adult Pterodactylus have been discovered, so that size is an estimate made by paleontologists, based on the size and development level of the many juvenile Pterodactylus fossils that have been found.
Pterodactylus was small and built for flight, so it wasn't designed with the kind of durability to fight. Perhaps they fought with other Pterodactylus, but there is no evidence that they fought with anything. If attacked, a Pterodactylus would just fly away, like a bird.

Pterodactylus never lived in North America. Pterodactylus fossils are only known from Europe and Africa.
There is only one species of Pterodactylus, Pterodactylus antiquus. However, there are many different types of pterosaur, or flying reptile. Pterodactylus and Pteranodon are probably the two most famous pterosaurs, and two other famous ones are Quetzalcoatlus and Ramphorhynchus.
No fossils of adult Pterodactylus have ever been found. However, paleontologists have estimated the size of adults based on the sizes and development levels of the many juvenile Pterodactylus fossils that have been found. They estimate that an adult Pterodactylus's wingspan was about 5 feet.
