This is an edited book with original scientific papers of the results of the 6th International Congress on Fossil Insects, Arthropods and Amber (FossilX3) held in Byblos, Lebanon in April, 2013. In the tradition of previous congresses, researchers from around the world gathered to discuss the latest developments and to build new co-operative endeavours. Recognizing that the future of our science is one of interdisciplinary collaboration, these meetings steadily grow in importance, and proceedings such as this reveal the latest hypotheses and conclusions, while inspiring others toward newer and greater goals.
