An egg is not a baby bird, but it will become one except if it becomes a baby snake. So begins this wonderful exploration of the unexpected. Even the shocking discovery the quickly loved main character (now known to be a dinosaur) is a fossil becomes joyful as readers learn of all the life the fossil harbors. A nice cyclical ending pulls the whole together perfectly. Simple, bright illustrations will capture even the youngest readers attention as will the expressive creatures they discover within it's pages. I loved this one!!
