A sequel to All Yesterdays, this book is based on the compilation of entries we received for the "All Your Yesterdays" contest of 2013, where we asked artists around the world to illustrate speculative but plausible ideas about dinosaurs and other extinct animals. From herbivores behaving badly to mimicry, parasitism, bizarre displays and even birth defects, here are visions of prehistoric creatures as you never expected to see them, from some of the best new talents in the field of paleontological art. All Your Yesterdays dwells further into the world of rational speculation with in-depth explanation and scientific references about each artwork.
