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
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 specimens at some of the sites, the species lived its full lifecycle in freshwater, with no travel from the highlands to the sea as in modern salmon.
==Distribution== Eosalmo driftwoodensis fossils have been recovered from locations in the Okanagan Highlands. Articulated skeletons are known from the type locality Driftwood Shales in Driftwood Canyon Provincial Park, near Smithers, British Columbia, the Allenby Formation surrounding Princeton, British Columbia, Canada and the southernmost highlands sites in the Klondike Mountain Formation surrounding Republic, Ferry County, Washington. Isolated skeletal elements reported from the Tranquille Formation at McAbee. Bone and scale material recovered from coprolites or regurgitalites at the Quilchena site in the Coldwater Beds has been identified as Eosalmo cf. driftwoodensis due to its fragmentary and partially digested nature.
