Before any reconstruction, the skull itself carries a substantial amount of information about Zlatý kůň, independent of the interpretive exercises that reconstruction involves.

The skull is gracile — relatively lightly built compared to archaic human skulls of comparable age, with thinner bone walls and less pronounced supraorbital tori (brow ridges) than Neanderthals or earlier Homo species.

This gracility is consistent with anatomically modern human morphology, and indeed the skull was classified as anatomically modern from the time of its first serious study.

The cranial volume falls within the range of modern Homo sapiens.

The overall brain size is comparable to living humans, reflecting the fact that by 45,000 years ago, the cognitive capacities associated with expanded brain size were already fully present in the modern human lineage.
