North America’s lost dogs: Recent ecological selectivity in the fossil record of mammalian carnivores
Large carnivorous mammals are rare in modern North American ecosystems, encouraging the perception that the costs of carnivory make diverse predator assemblages unsustainable. However, the rich fossil record of North American canids (dogs) reveals that large predators typically were not disadvantaged over the last 40 million years until approximately 11,000 years ago. This suggests that our current predator-poor scenario is the product of recent ecomorphological selectivity, inviting inquiry into how surviving carnivore species have changed through multiple environmental perturbations at the end of the last Ice Age.
