The era's name on an LCARS display

The Pre-Neskoromny Era was a cultural period on the planet Tagus III. Artifacts found in the ruins dating to this period were recovered by the Palinski Excavation of the University of Alpha Centauri. This excavation occurred prior to the sealing of those ruins by the Taguan government in the mid-23rd century. (TNG: "Qpid")

Information on this period is from an okudagram titled Tagus III Archaeological Notes which was perused by Captain Jean-Luc Picard in 2367.
It was named after assistant art director Andrew Neskoromny.
