Shantungosaurus giganteus is a Ornithopod who lived during the Late Cretaceous where today are the Shandong Peninsula, China. And 'one of the greatest representatives of his family, with known specimens 16.6 meters long and weighing more than 16 tons. It was described in 1973 by Hu. His tail had to be very long, probably used to balance the weight.

Magnapaulia laticaudus is a Ornithopod lived during the Late Cretaceous, between 76 and 73 million years ago, in California and Mexico. Once considered a congenerico of Lambeosaurus, now you know that it was instead a genre in its own right. was originally described with a length of between 15 and 16.5 meters and a weight of 25 tons, although it was later reduced to 12.5 meters and 16 tonnes. However, it remains one of the largest known Ornithopods.

Hypsisbemia missouriensis is a Ornithopod lived during the Late Cretaceous in Missouri. It was one of the greatest representatives of his family, perhaps by measuring up to 15 meters in length, although current estimates are lower, and 3 meters high. It was originally described as a small Sauropoda, and was originally named Neosaurus.

Who was the king?

None of them are king. Huaxiaosaurus makes 'em looks small.

I believe blaze has posted information as to why he thinks the reason Huaxiosaurus seems so big is a result of bad mounts.

Huaxiaosaurus dwarfs them all, but it might be just a huge Shantungosaurus specimen. It probably topped 19 meters and 25 metric tons! There are femurs over 6 feet long found! Sauropod sized!!! The mounts might be a tad off, but they individual bones prove there is a monster in there.

The largest femur reported is 172cm long.
The mount has quite a few more vertebra than any other Hadrosaur; the vertebral column was not uncovered in articulation, so the length is debatable IMO.

Likely an undiscovered species, but among the discovered ones, I would say Huaxiaosaurus...

There are supposedly much larger ones yet undescribed, one paleontologist said "they started at 170 cm, and just went up...".

^That guy said it is not clear if the material of Huaxiaosaurus doesn't belong to Shantungosaurus.

I have not included Huaxiaosaurus, because otherwise the choice was obvious.

Which is a Shantungosaurus sp.

Well, it is very well possible, but it is not solidly proven yet, so you can't take this as a fact either.

I would vote for Huaxiaosaurus cause it was probably larger than all three of them. However it isn't true that Huaxiaosaurus was dwarfing them. Magnapaulia might actually have been heavier.

Magnapaulia probably wasn't bigger at all

Being big don't make you the king....

If anything, Iguanodon would be the king, as it was the first named ornithopod.
