Ultrasaurus and Argentinosaurus are both among the largest known dinosaurs, but Argentinosaurus is generally considered to be larger. Argentinosaurus is estimated to have reached lengths of up to 100 feet or more, while Ultrasaurus is thought to have been around 80 to 100 feet long. However, the exact sizes of these dinosaurs are difficult to determine due to incomplete fossil records, leading to some debate among paleontologists.
