Our interdisciplinary study provides new information and interpretations of Ossuary I, a large assemblage of human bones associated with the ceremonial center dedicated to a life-size clay figure of a splendidly attired human skeleton (often identified as Mictlantecuhtli in the archaeological literature) at the site of El Zapotal in south-central Veracruz. Recovered in 1971, this assemblage has been interpreted as a ritual deposit of women who died during childbirth, whose bodies were dedicated in later Aztec lore to the Tlazolteotl goddess. The present paper provides new insights into the depositional sequence, the type and number of individuals within the assemblage, the sex and age profile of the mostly female cohort, the distribution of artificial head shapes as an ethnic marker, and evidence of perimortem violence and postmortem processing in the form of flaying. Our evidence indicates that Ossuary I represents the slow accumulation of loose bones and limb segments of partially skinned individuals in a circular shaft. Postdating the functioning of the Death God adoratorio and showing fluctuations in the patterns of pre-depositional body treatment, the assemblage expresses the Late Classic period ritual practice of flaying both males and females in Veracruz. In later stages, the ossuary was used again for a female cult, consistent with the original interpretation of women who died during childbirth. [ABSTRACT FROM AUTHOR]

El artículo se centra en el modelado del cráneo en Mesoamérica en relación a los valores culturales, costumbres cotidianas, expresiones del género y distinción social. Estas modificaciones artificiales representaron una expresión visible de identidad cultural.

In this study, we assessed the notable preservation of mercury‐enriched ancient dental remains. The studied specimen belonged to a 30‐year‐old woman, and it was collected from Temple XIII at the archaeological site of Palenque, Mexico (17°29'2.32"N, 92°2'46.78"W; a UNESCO World Heritage Site). The preservation of an ancient molar was studied by high‐resolution scanning electron microscopy and energy‐dispersive X‐ray spectroscopy (HRSEM–EDS), and the obtained results were compared to those recorded for contemporary tooth specimens. Measured and conventional carbon ages for the ancient molar were 1000 ± 30 and 1260 ± 30 bp, respectively. Energy‐dispersive spectroscopy (EDS) analysis showed that the accumulated Hg in the ancient molar was 66% (by weight). In contrast, the Hg content in the contemporary molar was observed to be below the analytical detection limits. Clearly, Hg accumulated preferentially in ancient dental structures. Aging favoured the overall exchange of Hg for structural Ca; namely, chemical migration from one dental compartment to the other, mineral transformations, enamel hypoplasia, and the accumulation of Hg and Al in bio‐organic structures. Overall, we observed excellent preservation of biogenic material with varying physiological function(s), including abundant odontoblasts (tubules and spheres), dentinal tubules and nervous system fibrils.

Maya civilization developed in Mesoamerica and encompassed the Yucatan Peninsula, Guatemala, Belize, part of the Mexican states of Tabasco and Chiapas, and the western parts of Honduras and El Salvador. This civilization persisted approximately 3,000 years and was one of the most advanced of its time, possessing the only known full writing system at the time, as well as art, sophisticated architecture, and mathematical and astronomical systems. This civilization reached the apex of its power and influence during the Preclassic period, from 2000 BCE to 250 CE. Genetic variation in the pre-Hispanic Mayas from archaeological sites in the Mexican states of Yucatan, Chiapas, Quintana Roo, and Tabasco and their relationship with the contemporary communities in these regions have not been previously studied. Consequently, the principal aim of this study was to determine mitochondrial DNA (mtDNA) variation in the pre-Hispanic Maya population and to assess the relationship of these individuals with contemporary Mesoamerican Maya and populations from Asia, Beringia, and North, Central, and South America. Our results revealed interactions and gene flow between populations in the different archaeological sites assessed in this study. The mtDNA haplogroup frequency in the pre-Hispanic Maya population (60.53%, 34.21%, and 5.26% for haplogroups A, C, and D, respectively) was similar to that of most Mexican and Guatemalan Maya populations, with haplogroup A exhibiting the highest frequency. Haplogroup B most likely arrived independently and mixed with populations carrying haplogroups A and C based on its absence in the pre-Hispanic Mexican Maya populations and low frequencies in most Mexican and Guatemalan Maya populations, although this also may be due to drift. Maya and Ciboneys sharing haplotype H10 belonged to haplogroup C1 and haplotype H4 of haplogroup D, suggesting shared regional haplotypes. This may indicate a shared genetic ancestry, suggesting more regional interaction between populations in the circum-Caribbean region than previously demonstrated. Haplotype sharing between the pre-Hispanic Maya and the indigenous populations from Asia, the Aleutian Islands, and North, Central, and South America provides evidence for gene flow from the ancestral Amerindian population of the pre-Hispanic Maya to Central and South America.
