Much younger remains of large, African amphicyonids have previously been referred to Amphicyon. Most notable among these are a molar and fragmentary postcranial remains from the Lower Nawatwa Formation, dating to 7.4 ± 0.1 – 6.5 ± 0.1 Ma, which represents one of the youngest amphicyonids known. Others tentatively refer this taxon to the genus Myacyon.
