Tyrannosaurus Wrecks! by Sudipta Bardhan-Quallen, illustrated by Zachariah Ohora is about a little T-Rex that destroys. He's not very popular with his classmates, as you can imagine, but when he tries to settle down and be more careful and not wreck everything, there are still disasters.
The illustrations in this book were made with Sumi ink and brush on Arches watercolor paper, with color added digitally. It's an engaging story that puts preschoolers as dinosaurs, which stays very true to how preschoolers are.
I'll use this in Preschool Storytime. Kids will love the big, bright colors, and the surprise ending.
