Rancholabrean  

Definition

  • The Rancholabrean North American Land Mammal Age on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from less than 240,000 years to 11,000 years BP, a period of 0.229 million years. Named after the famed Rancho La Brea fossil site (more commonly known as the La Brea tar pits) in Los Angeles, California, the Rancholabrean is characterized by the presence of the genus Bison in a Pleistocene context, often in association with other extinct Pleistocene forms such as Mammuthus. The age is usually considered to overlap the late Middle Pleistocene and Late Pleistocene epochs. The Rancholabrean is preceded by the Irvingtonian NALMA stage, and it is succeeded by the Santarosean age. On other continents, the Rancholabrean shares this time period with the Oldenburgian of European Land Mammal Ages, and the latter Lujanian of the South American Land Mammal Ages.
