Ultrasauros

About Ultrasauros The Ultrasauros may have lived around 150 million years ago during the late Jurassic Period. Actually, this dinosaur may have never lived at all. There is much debate today among scientists as to whether or not the fossils attributed to Ultrasauros were really bones from another dinosaur such as Brachiosaurus. If this animal did exist, it probably spent its life eating plants.
