Barstovian information


Syncline in the Barstow Formation (Barstovian) in Rainbow Basin near Barstow, California.
Cameloid footprint (Lamaichnum alfi Sarjeant and Reynolds, 1999; convex hyporelief) from the Barstow Formation (Barstovian) of Rainbow Basin, California.

The Barstovian North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 16,300,000 to 13,600,000 years BP, a period of 2.7 million years.[1] It is usually considered to overlap the Langhian and Serravallian stages of the Middle Miocene. The Barstovian is preceded by the Hemingfordian and followed by the Clarendonian NALMA stages.

The Barstovian can be further divided into the substages of:

  • late Late Barstovian: Lower boundary source of the base of the Langhian (approximate)
  • early Late Barstovian: Base of the Langhian (approximate)
  • early/lower Barstovian: Upper boundary source: base of Clarendonian (approximate)
