Hesperornis (Western Bird) was one of the largest birds of the age of dinosaurs. On land, it would have moved much like how penguins do today, not waddling mind you, but scooting along on its belly. It may have nested on isolated islands, or live birthed in the water. It’s webbed feet that faced backwards were ide3al for swimming and diving. It may have been one of the greatest (most well-adapted) predators of the ocean. It had many sharp teeth for gripping prey, a feature lost to birds after the mesozoic (excepting the occasional retroactive gene.) It could not fly, ans would be about the same size as an average sized man. It can be found in the North American Inland Sea, theTurgai Straight, and the North Sea regions in North America.
