I need some assistance with these assignment. the mistaken extinction Thank you in advance for the help! The book mainly underlines the assumptions which the different scientists have proposed which have become different schools of thoughts relating to the mystery of the extinction. It also at some point questions whether or not the dinosaurs are actually extinct or they have evolved into some higher species which we see around us. Thus the book puts forward an even more interesting proposition claiming that the dinosaurs may still be present among us only in an evolved fashion which we are not able to understand on distinguishing by our naked eye.

In the beginning, the book tries to underline all the given facts that we actually know about the extinction of the dinosaurs. It states that although the cause of the extinction is not known most scientists are sure of the period in which the dinosaurs ceased to exist, which the Cretaceous period. The Cretaceous period marked about some three-quarter extinction of both the plant life and the animal life in the form of dinosaurs. In Earth’s geological record the Cretaceous period can be marked as the K-Pg boundary which is found in both marine and terrestrial rocks. The book tries to solve the entire case of this mystery extinction just on the premise of solving a murder mystery in the several chapters which form the part one of the books.

The book is proposed to have two individual goals by which it tries to solve the mystery of the extinction of the dinosaurs. Firstly, it tries to distinguish the different hypotheses which are presented by different scientists during the different ages on the basis of scientific reasons. If scientific reasons are found for the hypothesis then the book has accepted them and carried forward in trying to analyze and establish them.&nbsp.
