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.
Muttaburra
In 1963 Muttaburra was the discovery site of the "Muttaburrasaurus", one of Australia's largest dinosaurs, by Doug Langdon The dinosaur is believed to have been long, high from the hip and weighing . It was a herbivore, with rows of grinding teeth, and probably ate plants such as ferns, cycads and conifers. It may have lived in herds. "Muttaburrasaurus" lived around 100 million years ago, during the Cretaceous period. Several specimens of this dinosaur have been found in central and northern Queensland, and a few teeth have been found in New South Wales. There is a full size replica in the town.
