Is the blue whale bigger then a t-rex?

The ultrasaurus is the only one larger than the blue whale, measuring at 572 ft. long and 509 ft. tall. Believe it or not, it's true. And no, it's not a popular dino. This dinosaur had a NECK longer than the whale, surprisingly at 299 ft. This was a long necked herbivore, and it walked on all-fours. A scientist named Coalinsa Magyreds Gimadersfret (Russian) discovered this and a creature named Ocroplosaurus. It took 4 cranes to lift Ultrasaurus off the ground, considering it weighs about 23,001 tons (46,002,000 pounds!!!!!)!!!!! There is 2 complete skeletons. 9 are incomplete.
