turtlebacks
Curved protective covers
Turtlebacks are raised, curved structures resembling the shell of a turtle.
In architecture and shipbuilding, a turtleback is a convex deck or roof that sheds water—common on early submarines and some railroad cars.
In geology, turtlebacks are dome-shaped rock formations exposed by erosion.
The word appears wherever something humps up like a turtle's carapace.
