• Species occupancy and its course in the past in the context of macroecological patterns in extinct communities were analyzed. Macroecological patterns in Ice Age communities of large-bodied mammals in Italy were observed. The occupancy patterns were tested in extinct communities to match a bimodal distribution as in living communities. Occupancy was regressed on species duration to estimate its effect on long-term survival. Null model of random occupancy trajectories was built and then compared to real data. The occupancy-frequency distribution in extinct communities was either bimodal or right skewed. Positive relationship between high occupancy and species survival was shown. Peaked occupancy trajectories were found to be the norm for hoofed mammals at least.
