The taxon has been described based on a complete skull and mandible from El Zapote cenote west of Puerto Morelos. We here add hitherto unreported postcranial material from El Zapote, attributed to the holotype. This new material allows us to reconstruct unexpected locomotion capabilities for Xibalbaonyx oviceps including steep slope and rock climbing. This may have enabled the ground sloth to use the sinkholes and underground caverns as water resource and shelter. The Late Pleistocene age of the fossil allows for a coexistence with early human settlers on the Yucatán Peninsula.

With respect to Maya cave architecture, high-resolution panoramic visualization and the production of 3D models can be powerful analytical tools, enabling the evaluation of potentially meaningful relationships between natural features and constructed features within a cave. A collaboration between the Instituto Nacional de Antropología e Historia (INAH) in Quintana Roo and the University of California, San Diego involves a study of at-risk cave shrines. Initial comparative and multiscalar analyses across terrestrial and subterranean environments provide insight into the form, function, and meaning of Postclassic cave architecture in the northeastern Maya lowlands.

During our ongoing paleoanthropological research we have already documented three well-preserved human skeletons as old as 13,000 and 9000 years from these sites in Quintana Roo (Gonzalez et al. 2008a, Gonzalez et al. 2008b). The findings were associated with hearths and a diverse megafaunal assemblage of late-Pleistocene age. A fourth human skeleton was discovered in 2009, two more in 2010, and two others in 2011. Here we provide a first register of these additional five skeletons, bringing the total assemblage to eight. A ninth skeleton was informally reported from the same area by INAH researchers. These findings thus constitute one of the largest databases on bones of early humans in Mexico.

These charcoal concentrations, interpreted here as ancient illumination sites, provide strong evidence that the Chan Hol cave was dry and accessible during that time interval. Humans used the cave for at least 1200 years during the early and middle Holocene, before access was successively interrupted by global sea level rise and flooding of the cave system. Our data thus narrow the gap between an early settlement in the Tulum area reaching from the late Pleistocene ($13 000 a) to middle Holocene (e.g. 7177 14 C a BP), and the Maya Formative period at approximately 3000 a bp. Yet, no evidence has been presented to date for human settlement during the $4000-year interval between 7000 and 3000 a. This is remarkable as settlement in other areas of southeastern Mexico (e.g. Chiapas, Tabasco) and in Guatemala was apparently continuous.

giant ground sloth, Xibalbaonyx oviceps (Megalonychidae,
Xenarthra), from the drowned cave system of the northeastern
Yucata´n Peninsula. The specimen is Late Pleistocene
in age and was discovered in the Zapote sinkhole
(cenote) near Puerto Morelos in the Mexican state of
Quintana Roo. Xibalbaonyx oviceps differs significantly
from all hitherto known Megalonychidae including those
from the Greater Antilles and South America. The new
taxon suggests a local Caribbean radiation of ground sloths
during the Late Pleistocene, which is consistent with the
dispersal of the group along a Mexican corridor.

Resumen: Innovadoras técnicas de captación y creación de imágenes y la visualización permiten la documentación y exposición de entidades y objetos dentro de sus contextos espaciales. En cuanto a la arquitectura maya en cuevas, panorámicas de gran resolución y la creación de modelos 3D se convierten en potentes herramientas de visualización y análisis y permiten la evaluación de potencialmente significantes relaciones entre las características naturales y construcciones humanas dentro de las mismas. Una nueva colaboración entre el Instituto Nacional de Antropología e Historia (INAH) en Quintana Roo y la Universidad de California en San Diego contempla estudiar antiguos santuarios subterráneos en alto riesgo. El análisis inicial a través de los entornos terrestres y subterráneos proporciona información sobre la forma, función y significado de la arquitectura postclásica maya en cuevas de las tierras bajas del noreste Maya.
