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.
