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.
Huanghetitan
A second species, "H. ruyangensis", was described in 2007 from the Aptian-Albian Haoling Formation of Ruyang County, China (Henan Province). A recent cladistic analysis has found that this species is (or more likely) not related to "H. liujiaxiaensis" and even requires a new genus name. It is known from a partial vertebral column and several ribs, the size of which (the largest approaches 3 m (10 ft)) indicate it had among the deepest body cavities of any known dinosaur. This second species, along with its local relatives "Daxiatitan" and "Ruyangosaurus", is one of the biggest dinosaurs ever found in Asia, and possibly one of the largest in the world.
