Like birds, Pterodactylus and all other pterosaurs had many tiny air sacs in its bones. The air sacs lowered the density of the pterosaur's bones, thus increasing its weight and making it easier for it to fly.
Yes they are hollow like a birds bones. which indicates that a dinosaur was more bird than reptile after all but some had bones that were not hollow.
So they can be lighter when they fly
no they are not at least not that i found
Yes as birds with hollow bones cannot fly for longer whereas penguins do not have hollow bones and are able to swim in rough tides for ages. Also non-hollow bones are stronger and tougher than hollow bones.

Ptarmigans, like many flying birds, have hollow bones. These light bones make it easier for the bird to fly. During the summer, the ptarmigans bones become heavier and stronger so they can withstand the stress of the ptarmigan's search for food. in the winter the bones become lighter so the bird can conserve energy while flying.
they have hollow bone and human bones are solid
I think a dinosaur has 985 bones
