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".
Aspex Gallery
More recently, Aspex was instrumental in bringing Heather & Ivan Morison's 'Luna Park' to Portsmouth in August 2010, in conjunction with Chapter, Cardiff, firstsite, Colchester and Safle. Part of the installation included a 53 foot recreation of an Ultrasauros on Southsea Common. The Ultrasauros was a dinosaur 'discovered' by the palaeontologist James A. Jensen in the 1970s. He claimed the set of giant bones that belonged to the largest dinosaur that ever lived. More than a decade later, however, it was revealed that his discovery was in fact a chimera, composed of bones from two different brachiosaur-type species.
