In North America around 66 million years ago, a solitary bull Alamosaurus sanjuanensis holds his long neck high in search of a potential mate. Alamosaurus would have been the last of the giant sauropod dinosaurs to roam the North American continent, living at approximately the same time as the famous Tyrannosaurus and Triceratops.
By the way, the scenery for this artwork was inspired by a viewing of the movie Jurassic World: Fallen Kingdom, specifically the scenes set on Isla Nublar during the first act.
