The first book in the Unhinged History series is a ripping yarnfull of adventure and deceitthat brings to life the best-known public spat in all of paleontology: the bitter rivalry between Edward Drinker Cope and Othniel Charles Marsh. This frenzy of discovery and one-upmanshipknown today as the Bone Warswas a gold rushlike scramble to find the most and best dinosaur fossils, thus bringing to glory to their respective home-base universities.

The true story of the invention, disasters, and adventures of the first bathysphere-a small, cramped, bare-bones spherical deep-sea submersible that set the world record for deepest dive in 1934. Explorer William Beebe and engineering grad student Otis Barton teamed up despite mismatched personalities and disagreements and changed deep-sea exploration forever. Told through engaging rhyme, this playfully illustrated addition to the Unhinged History series follows their journey from frustrated inventors to international celebrities. The tiny bathysphere was miserable to be in, with terrible lighting, little room to move, stale air, and minuscule portholes-but still the scientist-adventurers went far under the waves to experience the mysterious waters as no one ever had. After near calamities and false starts, Beebe and Barton saw, for the very first time, deep-sea creatures in their home environment, broke world records, and made history.
