Mid-Pliocene warm-period deposits in the High Arctic yield insight into camel evolution
The mid-Pliocene was a global warm period, preceding the onset of Quaternary glaciations. Here we use cosmogenic nuclide dating to show that a fossiliferous terrestrial deposit that includes subfossil trees and the northern-most evidence of Pliocene ice wedge casts in Canada's High Arctic (Elle...

The mid-Pliocene was a global warm period, preceding the onset of Quaternary glaciations.
