“…It is also known from the coastal site of Piedra Escrita, Peru, and three other caves in the Peruvian Andes, Jatun Uchco (2150 masl) and Trigo Jirka (2700 masl) in the Departamento de Huánuco and Cueva Roselló (3875 masl), Departamento de Junín [72]. Outside of Peru, it is known from the cave Baño Nuevo-1 at 750 masl 80 km, northeast of Coyhaique, Chile [73].…”

Late Pleistocene sloths were widely distributed and present in a diversity of habitats in South, Central, and North America and some Caribbean Islands. Late Pleistocene sloths include 27 genera in four families Megatheriidae, Megalonychidae, Mylodontidae, and Nothrotheriidae. There is no consensus on the number of valid species. Some sloths have wide geographic distributions and are present on multiple continents while others have a much smaller distribution. Our knowledge of the paleoecology and natural history of the different sloths varies greatly depending on their relative abundance. The wide distribution of sloths and adaptations to different habitats results in several “sloth” faunas with different taxonomic compositions. These generalized faunas can be distinguished geographically as Temperate North America (five genera), Southern Mexico and Central America (five genera), Northern South America (two genera), West Coast of South America (four genera), the Andes and Altiplano (four genera), Brazilian Intertropical Region (nine genera), Pampas-Patagonia and the Caribbean Islands (Cuba, Hispaniola, and Puerto Rico, four genera). Some genera may occur in multiple regions but are represented by different species. These regions also have differences in other mammalian taxa, so the sloths are often in ecological competition with different megaherbivores or preyed on by different carnivores.

Se describen e ilustran nuevos hallazgos de restos fósiles de uno de los escarabajos estercoleros de Pilauco, Onthophagus pilauco Tello, Verdú, Rossini y Zunino, 2021 (Coleoptera: Scarabaeidae), extinto en la base de la cronozona Younger Dryas, al fin del Pleistoceno (~12.800 años antes del presente) en la Patagonia norte de Chile. Análisis recientes de material procedente del sitio Pilauco permitieron registrar nuevos restos fósiles pertenecientes a O. pilauco, incluidos restos de clípeos con un cuerno central excepcional que asignamos a especímenes machos. Los nuevos descubrimientos nos permitieron revisar la descripción propuesta anteriormente por los descriptores y atribuir el sexo hembra al holotipo de O. pilauco. A la luz de los conocimientos actuales sobre el género, se discute la singularidad de este carácter fenotípico (i.e., cuerno del disco del clípeo) dentro de los Onthophagus americanos y la posible relación con grupos de la región asiática. A partir de esto, sugerimos que las novedades morfológicas observadas en O. pilauco, corresponden a rasgos únicos entre los Onthophagus americanos, que posiblemente se originaron a partir del aislamiento durante la última glaciación en la Patagonia norte de Chile.
