Almost every other animal could be considered its prey.How did this prehistoric creature live and hunt? How did it eventually become extinct? Sarah Thompson presents this scientific information with the emerging reader in mind—the text is simple, concise, and clear, yet full of useful and thought-provoking facts and ideas. Andrew Plant's illustrations, labeled throughout, provide readers with an accurate visual of the creatures presented.
