Sauroposeidon & Sycamore
A pair of 50 ton sauropod dinosaurs of the genus Sauroposeidon dine on the leaves of angiosperms of the genus Platanus (similar to today's American Sycamore) 110 million years ago during the Early Cretaceous Period in what is today southeastern Oklahoma. In the background flying reptiles known as pterosaurs glide across the sky.
A plant-eating giant, Sauroposeidon is the tallest known dinosaur with a neck that could reach up to 56 feet high. Sauroposeidon is also one of the longest and heaviest of all dinosaurs.
