We also observed an accumulation of higher latitude mammals in Mexico from 10-7 Ma. The pattern represents a ‘holding pen’ previously proposed by Flynn, Woodburne, and colleagues. However, this holding pen is more than twice as old as what they saw with earlier, less complete fossil records. (7/11)

We estimated diversification rates and faunal connectivity patterns across the Americas, vetting taxonomic occurrences and accounting for uncertainties in fossil age ranges. We discovered a latitudinal signal of fossil mammal movements in the 7 million years leading up to GABI pulses (6/11)
