Unlike the tails of most carnivorous dinosaurs, Spinosaurus’ tail bones were not interlocked, and that suggests the tail could wiggle more, undulating back and forth in a snakelike motion. “It produced way more thrust than other dinosaur tails; more in line with what you expect to see in a modern semiaquatic animal like a crocodile or a salamander or a newt,” Pierce said. “You try dragging a big billboard through the water,” Henderson said.
