Gelastops (Gelastops — „veselo lice”) je izumrli rod placentalnih sisara iz kladusa Scrotifera, koji je u periodu srednjeg paleocena nastanjivao područje Sjeverne Amerike.^[2]^[3]^[4]

Istorija klasifikacije[uredi | uredi izvor]

Rod Gelastops je originalno bio opisan kao predstavnik izumrli porodica Deltatheridiidae^[1] i Leptictidae.^[1]^[5] U kasnijim istraživanjima je ovaj rod uvršten kao predstavnik izumrli porodica Palaeoryctidae^[6]^[7] i Cimolestidae.^[4]^[8] U istraživanju iz 2015. godine je rod Gelastops bio uvršten kao predstavnik miroreda Ferae.^[9] Ovaj rod je u mnogim istraživanjima prepoznat kao blizak srodnik izumrlog roda Acmeodon^[1]^[7]^[9]^[10]
