Ravenictis (Raveniktis — „ravenskragska lasica”) je izumrli rod placentalni sisara iz kladusa Carnivoramorpha, koji je u periodu ranog paleocena nastanjivao područje Sjeverne Amerike.^[1]^[2]^[3]^[4]

Etimologija naziva

Rod:	Porijeklo naziva od:	Značenje naziva:
Ravenictis	geološke formacije Ravenskrag (u kojoj su pronađeni fosilni ostaci ovog roda) i latinske riječi iktis (lat. ictis), koja znači lasica	ravenskragska lasica

Vrsta:	Porijeklo naziva od:	Značenje naziva:
R. krausei	roda Ravenictis i prezimena američkog paleontologa Dejvida V. Krausa	krausov Raveniktis

Opis

Vrsta Ravenictis krausei je bila mali kopneni svaštojed^[5] nalik na današnje kune i mungose.^[6] Zubi vrste Ravenictis krausei po svojoj građi su ličili zubima vrsta iz izumrle porodice Viverravidae.

Sistematika

Istorija klasifikacije

Od kako je prvi put opisan, tačan položaj roda Ravenictis je bio nepoznat. Jedno vrijeme, ovaj rod je bio uvrštavan unutar izumrlog reda Cimolesta,^[1] no u kasnijim istraživanjima je ovaj rod prepoznat kao primitivni predstavnik kladusa Carnivoramorpha.^[6]
