What was the world like a long time before humans arrived on Earth? This book offers an account of the dinosaurs - but from a slightly different perspective. A Lost World is a book-banded reading book for more confident readers, carefully levelled at White Book Band. Illustrated throughout with beautiful photographs, this 818-word non-fiction book features a more demanding text with extended vocabulary and literary devices. It is suitable for ages 7 - 8. A Lost World is part of Ransom Reading Stars, a structured programme for children learning to read. The series has fifteen levels: four phonics levels and eleven book band levels (Pink through to Lime).
