The dinosaur begins making its way down the east coast of North America, sinking a fishing ketch off the Grand Banks, destroying another near Marquette, Canada, wrecking a lighthouse in Maine and destroying buildings in Massachusetts. Nesbitt eventually gains allies in paleontologist Thurgood Elson and his young assistant Lee Hunter after one of the surviving fishermen identifies from a collection of drawings the very same dinosaur that Nesbitt saw. Plotting the sightings of the beast's appearances on a map for skeptical military officers, Elson proposes the dinosaur is returning to the Hudson River area, where fossils of Rhedosaurus were first found. In a diving bell search of the undersea Hudson River Canyon, Professor Elson is killed after his bell is swallowed by the beast, which eventually comes ashore in Manhattan. A later newspaper report of its rampage lists "180 known dead, 1500 injured, damage estimates $300 million".
