Eosalmo is an extinct genus of ancient freshwater salmonid with a single described species Eosalmo driftwoodensis. The genus lived during the Eocene epoch and has been recovered from late Ypresian fossils in the Eocene Okanagan Highlands of the northwestern United States and western Canada. Additional fossils briefly mentioned as Eosalmo were reported from Russia, but they have not received close taxonomic treatment since. E. driftwoodensis is used as a phylogenetic calibration point for studies of the relationships in Salmonidae and Salmoniformes. Based on preservation of juvenile to adult sp

Ypresiomyrma is an extinct genus of ants in the subfamily Myrmeciinae that was described in 2006. There are four species described; one species is from the Isle of Fur in Denmark, two are from the McAbee Fossil Beds in British Columbia, Canada, and the fourth from the Bol’shaya Svetlovodnaya fossil site in Russia. The queens of this genus are large, the mandibles are elongated and the eyes are well developed; a stinger is also present. The behaviour of these ants would have been similar to that of extant Myrmeciinae ants, such as solitary foraging for arthropod prey and never leaving pheromone
