Gracilocyon (Gracilokion — „vitki pas”) je izumrli parafiletski rod placentalni sisara iz kladusa Carnivoraformes, koji je u periodu od kasnog paleocena do ranog eocena nastanjivao područje Sjeverne Amerike i Evrope.^[2]^[3]

Opis

Vrste iz parafiletskog roda Gracilocyon su bile mali kopneni svaštojedi koji su u prošlosti Sjeverne Amerike i Evrope nastanjivali plavne ravnice i kopnene ekosisteme. Vrsta Gracilocyon rundlei je težila oko 0,257 kg, a Gracilocyon solei oko 0,165 kg^[3] i po veličini dostizale dimenzije današnje velike lasice.

Sistematika

Istorija klasifikacije

Rod Gracilocyon je u prošlosti bio uvrštavan unutar izumrle porodice Miacidae, ali je kasnije prepoznat kao predstavnik kladusa Carnivoraformes.
