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".
Aramberri, Nuevo León
In 2002, Aramberri, attracted national and international media attention when it was announced the discovery of a large Pliosaur fossil, often referred by the press as "the Aramberri Monster", as they believed it looks like the Lochness Monster. The specimen is actually a very large pliosaur, possibly reaching 15 m (50 ft) in length. The media published exaggerated reports claiming it was 25 m (80 ft) long, and weighed up to 150,000 kg, which would have made it the largest predator of all time. This error was dramatically perpetuated in BBC's documentary series "Walking with Dinosaurs", which also prematurely classified it as a Liopleurodon ferox. On January 7, 2003, the fossil was transferred and reconstructed at the Natural History Museum of Karlsruhe in Germany, and was kept in exhibition until 2003, when it was transferred to the Museo del Desierto in Saltillo, Coahuila. The fossil is on exhibition at the Museo de historia Mexicana in Monterrey.
