Lower Cretaceous 110–100 mya
The name Ultrasaurus suggests a huge size, but actually it is rather a small sauropod. The researcher thought one of the limb bones was an ulna, an arm bone. So he thought the animal was a large sauropod. Later, it became clear that the bone was a humerus, a thicker arm bone. The bone was not complete, so the mistake was perhaps easy to make. As a result, the animal must have been smaller than previously thought.
The genus Ultrasaurus is currently a nomen dubium, a doubtful name, because it is based on too few remains. Not enough is known about the specimen to put it into a specific family of sauropods. It may even be a juvenile of an already known genus or species.
