Palaearctonyx ("ancient bear's claw") is an extinct genus of omnivorous placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene. ^{[2] [3] [4] [5]}

Classification and phylogeny

Classification

Palaearctonyx was named by Matthew in 1909 and it was assigned to family Miacidae. Later, it was assigned to Caniformia by Flynn and Galiano in 1982, ^[6] and then back to Miacidae by Flynn in 1998. ^[4] From 2010 and later, this genus was assigned to clade Carnivoraformes. ^{[7] [8] [9]}
