Refe and Susan live in Kansas City with their four children and a herd of plastic dinosaurs. The Tumas began cataloguing their dinosaurs' antics in 2012, creating Dinovember and igniting the imaginations of hundreds of thousands of children--young and old--across the world.

Refe and Susan are the authors of the What the Dinosaurs Did picture book series, including What the Dinosaurs Did Last Night, What the Dinosaurs Did Last Night: A Very Messy Adventure and the upcoming What the Dinosaurs Did At School.
