Fig. 1. Temporal range of temnocyonine amphicyonids in North America during the Paleogene- Neogene transition relative to ranges of other large carnivores (modified from Hunt, 2004, 2009, where Intervals A–C are defined: see Age and Correlation). Temnocyonine and daphoenine amphicyonids survived the North American Large Carnivore Turnover Event, placed here at the present Oligocene- Miocene boundary (Lourens et al., 2004).
