Dinosaur size
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
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.
