Petrified wood consists of ancient trunks and timber whose organic material was replaced by minerals over extended geological time, preserving the shape of the wood, its rings, and its detail in stone. These are not merely distinctively shaped objects — they are a physical record of the earth’s history, of ancient environments, and of the transformations the Arabian Peninsula passed through. Fossilised coral displayed alongside them gives a visitor tangible proof that today’s environment is not the only one this land has known.
