Sauroposeidon
The press release in 1999 immediately garnered international media attention, which led to many (inaccurate) news reports of "the largest dinosaur ever!". While "Sauroposeidon" likely represents the tallest known dinosaur taxon, it does not hold records for either the longest or most massive. "Patagotitan" or "Argentinosaurus" make better candidates for the title "World's Largest Dinosaur" (presuming to ignore, as is conventional, "Amphicoelias"), though incomplete fossil evidence makes exact rankings impossible.
Sinoceratops
"Sinoceratops" was a medium-sized, averagely-built, ground-dwelling, quadrupedal herbivore. It could grow up to an estimated length and height, and weigh up to . It was the first ceratopsid dinosaur discovered in China, and the only ceratopsid known from Asia. All other centrosaurines, and all chasmosaurines, are known from fossils discovered in North America, except for possibly "Turanoceratops". "Sinoceratops" is also significant because it is one of the largest known centrosaurines, and is much larger than any other known basal members of this group.
