Gorgonops (nimen merkitys: ”gorgonkasvo”) on sukupuuttoon kuollut Gorgonopsiaan kuuluva terapsidisuku, joka eli myöhäisellä permikaudella. Sukuun kuuluu nykykäsityksen mukaan kuusi lajia, mutta niistä vain yksi, Gorgonops torvus, tunnetaan hyvin. Tämän lisäksi se on ensimmäisiä tieteelle kuvattuja nisäkkäitä edeltäneitä terapsideja. Gorgonopsin fossiileja on löydetty Afrikasta, erityisesti Etelä-Afrikasta.[1][2][3]

Gorgonops whaitsiin kallo


Gorgonops oli keskikokoinen Gorgonopsian jäsen; se oli 1,2 metriä pitkä, ja sen kallon pituus on noin 22 cm. Gorgonopsilla oli muiden Gorgonopsian jäsenten tavoin pitkät ns. sapelihampaat.[2][4] Jotkut tutkijat ovat väittäneet Gogonopsin olleen tasalämpöinen, mutta teoriaa ei ole kyetty todistamaan.lähde?



Saaliit |


Gorgonops saalisti todennäköisesti dikynodontteja ja matelijoita, joiden kanssa se jakoi elinympäristönsä. Kivettyneistä ulosteista koproliiteistä, jota ovat todennäköisesti Gorgonopsin tai Aelurognathusin jäljiltä, on löydetty eläinten jäänteitä, jotka mitä todennäköisimmin kuuluvat nopeasti kasvaneille dikynodonteille ja hitaasti kasvaneille matelijoille.[5]
