The Red Queen remains (700 A.C.) found at Palenque, México, are examples of cinnabar (HgS) application to royal remains during pre-Hispanic times. The Red Queen remains are those of aca.30–35-yr-old female and present a striking similarity to the remains of another Mayan woman found at Copan, Honduras. Thus, covering the remains of royal women with HgS may have been a common practice in the Mayan civilization. High resolution microdiffraction and microscopic analysis of the Red Queen remains showed the presence of nanotubular organic minerals comparable in composition and molecular dimensions to collagen fibrils, and in spatial ordering to collagen fiber networks. Fungal structures are rare in the geological record because of poor preservation potential. Micrographs revealed the preservation of fungal signatures, with morphology comparable to parasitic fungal-coral matrix associations, consistent with the idea that fungal remains can be preserved in environments which contain high Hg concentrations. The well-preserved signatures of fungus-animal interactions and primary osteogenesis in the Red Queen remains are attributed to the long-term antibacterial activity of HgS and the association of sulfur components with nanotubular structures.
