I am not going to try to show any images of this creature becuase I have lost track of which one is which one. I list it separately to make the point that he did infact find a seond ultra-large sauropod. I just canít sort them out at this point in time. So please look at the Ultrasaurus images for an idea about th size of this thing.
Indeed, there is controversy about his naming of these large sauropods. It appears that he mistakenly renamed bones from a known specie as a new specie. See his Publications for some more -though not much- detail about this problem. You can find the subsequent publications that addresssed the problem.
