Little Kids First Big Book of Dinosaurs (2017)

For the four-year-old who already knows more dinosaur names than you do. Catherine D. Hughes covers 52 species, grouped by size from small to gigantic, which suits the way young children actually sort dinosaurs. Each spread gives a phonetic pronunciation, so the adult reading aloud stops guessing, and a chart comparing the animal's size with a person. A map of fossil finds and a glossary round it out. Franco Tempesta's illustrations are large and vivid without being gory, and the text is short enough for a new reader to tackle alone.
