“…These limestones were part of a quarry that used dynamite for rock exploration and, due to the explosions, most of the material suffered anthropogenic fragmentation, as can be evidenced in the 3 rd lophid of the right M 2 element FX-800. The report of the right DP 4 (FX-801) molar increases the South American immature proboscidean record, which in most cases are compounded by adult individual remains (Andrade et al, 2020).…”

Proboscideans arrived in South America from North America during the Great American Biotic Interchange, becoming one of the most representative animals of the megafauna that inhabited this continent throughout the Quaternary. In Colombia, the abundance of their remains contrasts with scarce scientific descriptions and publications. This paper identifies dental and postcranial proboscidean fossils from the Center and Northeast of Colombia. The fossil remains were identified as molars (six), a tusk, cervical vertebrae, and a distal part of the right humerus. The tusk was assigned to Notiomastodon platensis, while the other remains were assigned to Gomphotheriidae, with at least six individuals: two immatures, two subadults, and two older adults – mature and senile. Keywords: South America, megamammals, taxonomy, Gomphotheriidae, Notiomastodon platensis.

“…Figura 3. Para determinar la ubicación anatómica de las piezas dentarias se utilizan las imágenes propuestas por Simpson y Paula Couto (1957), dado que varios autores (Frassinetti y Alberdi, 2000;Alberdi et al, 2002;Christiansen, 2004;Chávez-Aponte et al, 2008;Mothé et al, 2012;2016;2019;Mothé y Avilla, 2015;Andrade et al, 2020), coinciden en que esta propuesta considera de forma rigurosa y tiene suficiente información sobre la variabilidad en la morfología molar de los mastodontes suramericanos.…”

Este trabajo se enfoca en la descripción de muestras fósiles pertenecientes a proboscídeos del Cuaternario de América del Sur, depositados en el Museo de Historia Natural de la Universidad del Cauca (Popayán, Colombia). Se sintetiza la información recabada a partir de las piezas de dicho grupo, utilizando la anatomía comparada con ejemplares de otros institutos y referencial bibliográficas adicionales. Se realiza una comparación de las medidas tomadas (en milímetros) de las muestras analizadas para obtener aproximaciones de su identificación taxonómica, edad y biomasa, esta última aplicada específicamente a los elementos postcraneales. Las muestras se componen de dientes M2, M3, bunodontes, trilofodontes y pentalofodontes (carentes de defensas) encontradas en cercanías al desierto de la Tatacoa (Huila) y un molar M1 bunodonte fragmentado, encontrado en Mercaderes (Cauca), además de elementos postcraneales (una patela y una vértebra) encontrados en una tumba indígena en el Valle de Atríz (Nariño). A partir de las características morfológicas identificadas en este trabajo, los registros de las tres localidades se clasifican como Notiomastodon cf. platensis. El reporte de esta información contribuye significativamente a reforzar los estudios paleobiológicos sobre la presencia de Notiomastodon como componente destacado de la megafauna del Cuaternario en el sur occidente de Colombia.

An integrated taphonomic analysis was applied to a tank deposit from the Zabelê Palaeontological Site (ZPS) in northeast Brazil. The unique sedimentological evidence documents the origin of the mammal assemblage via debris flow. Optically stimulated luminescence (OSL) dates put the ZPS in the later Marine Isotope Stage (MIS) 3, which was a time when it was colder and there were fewer trees. The study revealed that the Zabelê's periphery accumulation was the result of the short transport of specimens and their entrainment by debris flow. This hydraulic transport caused the preferential orientation of the bioclasts (north–southwest). Comparisons were made with other Pleistocene tank deposits, suggesting the occurrence of common megamammal taxa. Temporal mixing was evidenced by the long time interval recorded by OSL ages and the co‐occurrence of distinct degrees of fragmentation, weathering, and fossil diagenesis. Permineralization and staining of Fe3+ and Mn colour patterns were identified as fossilization processes with preservation of the original bone hydroxyapatite without substitution. The comparison with other tank deposits revealed common signatures (disarticulated and fragmented with moderate abrasion) and signs of reworking. Finally, the savanna‐adapted herbivore megamammals from ZPS, such as Eremotherium, Notiomastodon, Toxodon, and Glyptotherium, are congruent with the forest decline from MIS 3 to the Last Glacial Maximum.
