This is a jigsaw puzzle that’s four times the fun! Put together four detailed dinosaur scenes--apatosaurus, tyrannosaurus rex, stegosaurus, and triceratops--then link them together to create a more than five-foot-long emergency prehistoric scene. Mix and match the linking puzzles (approximately 17 x 11 inches each) for different looks. Pieces are shape-coded on the back for easy sorting, and are coated with an Easy-Clean surface that keeps the linking puzzles looking like new. Puzzle play is a wonderful way for children to have fun while developing physical, cognitive, and emotional skills like fine motor skills, problem-solving skills, memory, and patience.
