acquired its name from its superficial similarity to another bear
Depending upon the palaeontologist, Paradaphoenus
has been assigned a more general position within the Amphicyonidae,
as well as a more precise classification within the Daphoeninae, the
group named after Daphoenus.
At almost two kilos Paradaphoenus was one of the smaller bear dogs and initially lived in North America at a time when the top predators were creodont mammals like Hyaenodon horridus. Continuing climatic changes in the Miocene as well as the arrival of truly large bear dogs like Amphicyon would signal the end of the creodonts as top predators. Throughout this time Paradaphoenus would have continued to be near the bottom of the food chain where it probably focused its attentions upon hunting smaller mammals as well as probably scavenging the leftovers of the kills of larger predators.
