Etymology
Diplodocoidea is derived from the Greek "diploos" (double) and "dokos" (beam), and the Latin "-oidea" (likeness, form, resemblance), in reference to the double-beamed bones (chevrons) on the underside of their tail vertebrae, and their relationship to Diplodocus. In the Linnaean system of classification "oidea" is applied to groups which rank as "superfamilies".
