The Alarm Pterosaur is a flying reptile of an unknown species (possibly a Pteranodon) who sits in the Sauropod and squawks loudly whenever the ship is under threat. She is one of a few pterosaurs who can speak the dinosaur language. She is good friends with Sprite. She is very nervous and likes to drink swamp tea to calm her nerves when off duty. Her real name is Terri Alarmosaurus, and Teggs first refers to her by name in The Dreams of Dread. She was hatched on Squawk Major.
