Tiffanian

The Tiffanian North American Stage on the geologic timescale, is a North American faunal stage within the North American Land Mammal Ages chronology (NALMA). It occupies part of the Paleocene epoch, spanning an interval from about 60,900,000 to 57,500,000 years Before Present, lasting 3.4 million years.

The Tiffanian overlaps with part of the Selandian (Middle Paleocene) and Thanetian (Late Paleocene), which are stages on the global timescale. In regards to NALMA, the Tiffanian is preceded by the Torrejonian and followed by the Clarkforkian NALMA stages.
