"In the Jurassic and Early Cretaceous periods, the world's flora was dominated by an extinct group of cycad-like plants called bennettitales. Nilssoniacladus is one of the youngest representatives. It is a salt-tolerant plant found commonly near the sea."

― Saurian encylopedia

Nilssoniacladus yukonensis was a member of the extinct order Bennettitales. The Bennettitales (or cycadeoids) or quite abundant in the Mesozoic, but entered in decline after the K-Pg Extinction event, and only some members of the group managed to survive until their ultimate extinction in the Oligocene. Any role that it may have in a future herbivorous gameplay, is unknown, but it is noted it is probably a salty plant in taste, which may be a factor to its edibility.
