Conversation

Did you know that a pterosaur was one of the first flying reptiles?

Really? I always thought they were more like dinosaurs.

They lived during the same time, but they are their own unique group.

That's interesting! I need to read more about these prehistoric creatures.

Root Explanation

Pterosaur → It is formed from "ptero-" (from Greek "pteron", meaning wing) and "saur" (from Greek "sauros", meaning lizard). The word "pterosaur" refers to a winged lizard, describing a group of flying reptiles that lived during the age of dinosaurs.

Memory Tip

Imagine a 'wing' ('ptero-') and a 'lizard' ('saur') together — that's why pterosaur means a winged lizard.
