There were many different types of pterosaurs. The largest known pterosaur was Quetzalcoatlus, and may have weighed as much as 500 pounds, although it is not certain that it was able to fly. The small pterosoaurs, however, probably weighed about the same amount as average birds do today.
Most pterosaurs traveled primarily by flying. However, all pterosaurs were capable of walking. They were quadrupeds, walking by folding their wings and using their wings and feet to bear their weight.
There were many species of pterosaurs, ranging from small, such as the Pterodactylus, with only a 5 foot wingspan, to huge, such as the Quetzalcoatlus with a 33 foot wingspan. Quetzalcoatlus weight estimates range from 150 to 550 pounds. Of course, a small pterosaur like Pterodactylus would have only weighed a pound or so, maybe less.
Yes, pterosaurs did walk at times. Fossilized tracks show that pterosaurs were quadrupedal. They folded their wings and thus could bear part of their weight on the fingers at the front of their wings. In addition, they were plantigrade, meaning that they walked on the entire sole of their foot, not just their toes.
No. Pterosaurs are extinct and humans never met the dinosaurs/pterosaurs.
Paleontologists believe that pterosaurs were warmblooded. Flight takes so much energy that it is believed that for a vertebrate to fly, it would have to be warmblooded.
Yes, pterosaurs were flying creatures.
All known pterosaurs were carnivores. There is no evidence that any pterosaurs ate any plants at all, and thus it is safe to say that at least most, if not all pterosaurs were hypercarnivorous.

There are hundreds of known species of pterosaur, and that is only a fraction of the total number of species of pterosaur that existed, as people have only discovered a small percentage of them. Different pterosaur species grew to different sizes. One of the smaller pterosaurs was Pterodactylus, which had an adult wingspan of about 5 feet. The largest well known pterosaur is Quetzalcoatlus, which had a wingspan of 33 to 36 feet. It may have weighed as much as 440 to 550 pounds, but there are no modern animals with a similar body plan to pterosaurs and thus determining their weight is nearly impossible.
no
The only known reptiles to have evolved powered flight were pterosaurs. Thus, all pterosaurs were flying reptiles and all flying reptiles are pterosaurs.
Pterosaurs were quadrupeds, meaning that they walked on all fours. Their wings had three fingers on the middle of the front edge. When on walking, pterosaurs would fold their wings so that their fingers would rest on the ground and bear some of their weight, and they would walk on all fours in that way. Unlike most animals, they were plantigrade, meaning that they walked on their entire foot instead of just their toes.
