Unnamed humanoids (Distant past)
From Memory Alpha, the free Star Trek reference
[edit] Rock carving humanoids
In 2152 an NX-01 Enterprise away team studied the ruins of a mysteriously disappeared civilization on an unnamed planet. On the walls of a building that was 4000 years old, they found several depictions of humanoids. (ENT: "Vanishing Point")
The carvings were too stylized to see if they depicted a single species in varying symbolic ways, or several. They might have depicted either the species themselves, or perhaps their mythological figures
