The Somethingosaur by Tony Mitton / Russell Ayto.
Where the dinosaurs roam a little creature hatches from an egg. This book goes on a little adventure where the creature tries to find its mother.
My favourite part of the pictures in the book is when “He wanders the deserts, the swamps and the plains. He travels through blistering heat and trough rains. He visits the places that no dino knows.”
