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.
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.
