Many people grew up believing that dinosaurs became extinct when the Dark Ages arrived, but that's only partly true. Yes, the Dark Ages did come, but one cranky dinosaur survived and became mankind's oldest ancestor: the TyrantoCrankaTsuris. In this playful, imaginative tale that draws inspiration from Jewish culture, author Steven Joseph reminds children and adults alike that we all have a little TyrantoCrankaTsuris in us and encourages readers to balance their woes with the positive things in life in pursuit of a happier world.
