Anachronism
An anachronism was something that seemed as though it was left over from another era of time, due to its defining characteristics.

In 2365, Doctor Katherine Pulaski described the Bringloidi as having been anachronistic in 2123 and wondered how they would manage in the 24th century. William T. Riker surmised they would be able to learn and successfully adapt to their new way of life. ()
