This allowed them to feed tough vegetation that might not have been edible to other species. They were also able to browse very high in the trees, as evident by their immensely long necks. Based on the time period, researchers believe they likely fed on cycads, ginkos, tree ferns, and conifers.
The Brachiosaurus is a sauropod dinosaur. These very large dinosaurs are often characterized by having very long necks and tails. Some of these dinosaurs were among the. Brachiosaurus (/ ˌ b r æ k i ə ˈ s ɔː r ə s /) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about – million years ago.
