These have been interpreted as either taphonomically mixed or representative of communities that no longer exist. Accelerator mass spectrometry 14C dates (n = 60) on single bones of stratigraphically associated fossil micromammals from two American and two Russian sites document for the first time that currently allopatric mammals occurred together between 12,000 and 22,000 yr B.P. on two continents. The existence of mammal communities without modern analogs demonstrates that Northern Hemisphere biological communities are ephemeral and that many modern biomes are younger than 12 ka. Future climate change may result in new nonanalog communities. This content is PDF only. Please click on the PDF icon to access.
