Ultrasaurus facts for kids
Temporal range: Lower Cretaceous
Ultrasaurus is a doubtful name (nomen dubium). Not enough is known about the specimen to put it into a specific family of sauropods. It may even be a member of a known genus or species, which would make the name Ultrasaurus a junior synonym as well. It is only known from part of an upper forearm (humerus), and some back bones (vertebrae).
