Sauropod dinosaurs of the genus Sauroposeidon graze on angiosperms of the genus Platanus (similar to today's American Sycamore) and angiosperms of the genus Magnolia (similar to today's Southern Magnolia) while feathered carnivorous dromaeosaurid dinosaurs of the genus Deinonychus look on. The location is a river delta on the Western Interior Seaway 110 million years ago during the Early Cretaceous Period in what is today southeastern Oklahoma.

Sauroposeidon is the tallest known dinosaur with a neck that could reach up to 56 feet high. Deinonychus on the other hand was a relatively small predator, 11 feet long and standing about three feet tall at the hip. It was a close relative to the smaller velociraptor which emerged later in Central Asia. Deinonychus wasn't powerful enough to bring down a giant like an adult Sauroposeidon, however they did likely prey on juvenile or sick adults.
