Front

What is the significance of the wingspan in pterosaurs?

Back

The wingspan in pterosaurs is significant as it indicates their size and ability to fly; larger wingspans generally allowed for greater flight capabilities.

Front

How did pterosaurs differ from dinosaurs?

Back

Pterosaurs are not dinosaurs; they are a distinct group of flying reptiles that lived alongside dinosaurs but belong to a different clade.
