Microscopic analysis of Zavacephale rinpoche's limb bones showed it was immature and still growing when it died, despite already having a fully domed skull.

Confirmed by multiple independent sources including NC State News, ScienceAlert, NHM, and Wikipedia's detailed histological account (lack of suture fusion, no external fundamental system, tibia cortex remodelling), all citing the original research on the Zavacephale rinpoche holotype.
