Maybe the Stegosaurus tail moves up when motion is applied, but goes down when it is not moving. By fossil record, it shouldn’t be like that, and thus, the tail being broken (not as in literally broken, but as in it is still able to swing it, but it drags down). Imagine a Stegosaurus, able to move its tail up and down to swim in water.
