De cabezas y lenguas en los reinos mayas. Cambios versus permanencia durante y tras el colapso
Las modificaciones cefálicas artificiales en infantes estuvieron a cargo de las mujeres y fueron algunas de las prácticas más difundidas entre los mayas prehispánicos, con resultados tan diversos como visibles en los semblantes de los mayas del periodo Clásico. En este artículo se exploran sus significaciones identitarias, potencialmente étnicas, a través de los territorios mayas y más allá. Para este fin hemos revisado la cartografía de los vestigios humanos mayas, sus retratos y las inscripciones, los cuales en parte siguen la distribución de su habla en territorios políticos cambiantes y cada vez más divididos. Nuestras indagaciones trazan similitudes entre lenguas y formas cefálicas que a su vez dejan entrever antagonismos. Las diferencias se vuelven especialmente patentes entre los hablantes del ch’olano occidental, con sus testas alargadas e inclinadas, y aquellos de habla tzeltalana, zoque y k’iche’, quienes solían lucir una cabeza corta y ancha.

Root canal morphology of the mandibular first premolars in a yucatecan population using Cone beam computed tomography: An in vitro study
A successful endodontic treatment requires knowledge of the internal configuration of dental root canals. Most of the people who live in Yucatan are of Maya origin, characterized by a Mongoloid dental pattern. Because of their ethnicity, variations are expected. The purpose of this investigation is to assess the morphological characteristics and variability of this population. One hundred and five extracted first mandibular premolars of Mexican Maya population were analyzed; the sample was obtained from the Oral Surgery Clinic in the School of Dentistry at the Autonomous University of Yucatan with written informed consent. Analyses were performed by means of Cone Beam Computed Tomography. Vertucci´s Type I was the most prevalent configuration with 51.4 %, but 41 cases (39.1 %) presented a radicular groove and a C-shaped canal configuration. Overall, we documented 1, 2, 3, and 4 root canals. Mandibular first premolars are very variable in the Yucatecan population. The variability and frequency of C-shape is similar to mandibular second molars confirming the importance of the ethnic background for the endodontic treatments.

Calakmul as a central place: Isotopic insights on urban Maya mobility and diet during the first millenium AD
Isotopic investigations of human burials from excavations of the Autonomous University of Campeche (CIHS) at the prehispanic Maya capital of Calakmul in southeastern Mexico, near the border with Guatemala, include determination of radiocarbon dates; carbon and nitrogen isotope ratios in collagen; and strontium, carbon, and oxygen isotope ratios in tooth enamel. A total of 22 human and 5 faunal samples analyzed for strontium isotopes reveal a narrow range of variation in values, pointing to the likely local origin of over two-thirds of the central population of Calakmul, including two of its rulers. Carbon and nitrogen data confirm a typical Classic Maya diet at the site and identify a diet high in meat consumption for one dynastic individual. Interpreted jointly, the isotopic information offers new perspectives on the provenience and lifestyles of the residents of Calakmul, including a potential place of origin for the royal occupant of chamber tomb Burial VII-1.
