Edwina, the Dinosaur Who Didn't Know She Was Extinct is an American children's picture book written and illustrated by Mo Willems.

However, a boy named Reginald Von Hoobie-Doobie tries to convince everyone that dinosaurs are supposed to be extinct.

[1] Steve Johnson of the Wichita Eagle declared, "Willems has written a unique story every bit as good as the classic Danny and the Dinosaur.

"[2] Lana Berkowitz of the Houston Chronicle called it "a winner", [3] while The Courier-Journal's Jill Johnson Keeney said it was a "worthy successor" to Willems' earlier books, such as Don't Let the Pigeon Drive the Bus!

"[5] Explaining Reginald's last name to an interviewer, Willems said, "'Hoobie-Doobie' is my generic fill-in for when I can't think of a word (as in 'Hand me the Hoobie-Doobie, please.').
