The story in the book Dinosauriernas död, meteoriterna och livets väg builds on the author’s experience as a researcher during more than four decades. Thousands of articles and hundreds of books have been read during this period. In talks and discussions, the viewpoints of other scientists in many fields have been considered. Astronomers, geologists, biologists, physicists, anthropologists, theologists, and philosophers have shared their knowledge and experience. It is thus not possible to list the sources of all information in the book, but in the link here some of the selected reference literature is provided. In the compilation of articles and books and their reference lists the reader may find more in-depth information on issues at stake. Any reader that has found his way to the present text is also welcome to contact the author directly at birger.schmitz@fysik.lu.se with questions and/or comments. The author would be particularly thankful to be informed if any factual errors remain in the text despite extensive efforts to avoid this.
