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.
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.
