The jumbo Land of Dinosaurs Floor Puzzle features beautiful original artwork that depicts a dramatic scene from prehistoric times. Kids can learn about the different kinds of dinosaurs that once roamed the earth, as well as recognize some of their favorites including a giant T-rex, and flying pterodactyls. The large floor puzzle measures over four feet long when it's assembled, and the 48 extra-thick cardboard pieces feature an easy-to-clean surface to keep it looking like new. Playing with this puzzle is a great way for kids to explore the world of dinosaurs while developing their cognitive, physical, and emotional skills. When children work on puzzles, they are fine-tuning their gross motor skills, improving their hand-eye coordination, strengthening their problem-solving skills, and beginning to develop logic and critical thinking processes. This Melissa & Doug puzzle makes an exceptional gift for preschoolers and kids ages three and older for hands-on, screen-free play. This product is certified by the Forest Stewardship Council.
