Can a T. rex take a selfie? Will woolly mammoth's throwback Thursday photo get the most likes? What if prehistoric creatures were online? Kids are engaging in social networks in increasing numbers and this digital world has given birth to a new language--the hashtag language. #PREHISTORIC offers a unique opportunity to connect with kids in their language while introducing them to the incredible dinosaurs and animals of the prehistoric world. Each creature has its own humorous username and caption as well as a user info page that offers basic facts, stats, and photos. A comment section provides humorously imagined dinosaur banter. The hashtags also serve to present information in a contemporary voice. #PREHISTORIC is a melding of old and new and fun and informative, making nonfiction incredibly accessible for young readers.
