Shepard Tone: Named after Roger Shepard, a Shepard tone is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upward or downward, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower. It has been described as a "sonic barber's pole".

Shepherd's Crown: Some Cretaceous echinoids, notably Micraster, Echinocorys and Conulus, have distinctive shapes, leading to the name Shepherd's crowns in English folklore. The five rays converging on the apex of the fossil resemble the ribs of a crown. According to Bassett (1982), shepherds may have come across these fossil echinoids, weathered out of the underlying chalk, while caring for their sheep on the downlands of southern England.
