This book is written by two Phd.s, really smart guys, but written for children. But not written down to children, the two professors wrote in a way that children would rise up to assimilate. These guys, Lowell Dingus and Luis Chiappe are also interesting writers as writers, another unusual thing from academia. The book is about finding and using science to examine dinosaur eggs, a very narrow specialty if you ask me. But as I discovered, we can find out a lot about how dinosaurs lived and acted by a careful study of their fossilized eggs. I had no idea. They gave, as an example, the discovery of one dinosaur fossil where the adult fossil was situated above the fossil eggs. This indicated to the science guys that the adult sat on the eggs to protect them until the hatchlings came out. Prior to this, adult dinosaurs were thought to lay and leave. This might also happen, but not always. Our knowledge is becoming gradually deeper and wider. But it isn't easy. A good chunk of the book is a diary-like exposition of an expedition the two scientists made to Argentina in 1997 to look for fossils. It covers each day's events over a three-week period. We learn a lot about history, fossil hunting, geology, fossil eggs, and how a project of this type is organized and carried out. I have never seen a similar description, never mind a first-hand description of this sort of endevor. This book will be of use to adults and a definite challenge to younger children. Even high school-age young people will have to pay attention to grasp the language and concepts. This is not pablum for babies. Highly recommended.first the book is all of 42 pages woooohoooo!did they write this during a lunch hour?this book is a complete ripoff just a few good photos of the quarry and specimens found.its written for a 10 year old or less.i felt like an idiot reading this but i payed for it so i did in a half hour or so.what a waste of money.from now on im going to look it up on other sites before buying because amazon didnt post the amount of pages in this pamplet.
