A bird-like humanoid species with golden feathers and wings, introduced in the animated series through the historian Aleek-Om, who studies the past with the Guardian of Forever.
The Aurelians are one of the non-human designs that animation made possible. They are tall, feathered and winged, with beaked faces.
The species appears in Yesteryear, written by D. C. Fontana. The Aurelian historian Aleek-Om is part of the research team using the Guardian of Forever to review history while Kirk and Spock travel into Orion's past, and it is on their return that nobody recognises Spock, whose childhood death in the altered timeline must then be undone.
Aurelians should not be confused with the Skorr, the other winged race of the animated series, seen in The Jihad.
