Alamosaurus
Alamosaurus (; meaning "Ojo Alamo lizard") is a genus of titanosaurian sauropod dinosaurs, containing a single known species, Alamosaurus sanjuanensis, from the late Cretaceous Period of what is now southern North America. Isolated vertebrae and limb bones indicate that it reached sizes comparable to "Argentinosaurus" and "Puertasaurus", which would make it the largest dinosaur known from North America. Its fossils have been recovered from a variety of rock formations spanning the Maastrichtian age of the late Cretaceous period. Specimens of a juvenile "Alamosaurus sanjuanensis" have been recovered from only a few meters below the Cretaceous-Paleogene boundary in Texas, making it among the last surviving non-avian dinosaur species.
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.
