Parents need to know that this CD of songs about dinosaurs will entertain and educate the whole family, but the sophisticated music and vocabulary is more appropriate for the school-age child than the youngest ones. The 3-D cover graphic of a sharp-toothed dinosaur opening and closing its mouth might be scary for preschoolers, and there is mention of a mummy and T.Rex Sue's "58 teeth made to munch and crunch."
I played this for my kids (6 and 7) and they couldn't get enough. They loved the songs, especially ones that played on words (such as "How do you get to South Dakota?") They weren't as hot on the dialogue, but were able to recite a few key facts (eg, Sue is the most complete T-rex skeleton ever found, who made the discovery, where she was found) As a parent, I found the songs catchy and a lot of fun, especially nice to hear Al Jarreau and Martha Davis (formerly of the Motels).
