Aversor is an extinct genus of embolomere which lived in the Early Permian of Russia. It contains a single species, Aversor dmitrievi, which is based on skull and jaw fragments from the Intinskaya Svita (Inta Formation) near Pechora.[1] It may have been the youngest known eogyrinid, and was the youngest known embolomere until the discovery of Seroherpeton, a Late Permian embolomere described in 2020. Aversor and Seroherpeton both lived at higher latitudes than older embolomeres, suggesting that the group abandoned arid equatorial areas prior to their final demise.[2]
