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".
Velociraptor
Production on "Jurassic Park" began before the discovery of the large dromaeosaurid "Utahraptor" was made public in 1991, but as Jody Duncan wrote about this discovery: "Later, after we had designed and built the Raptor, there was a discovery of a Raptor skeleton in Utah, which they labeled 'super-slasher'. They had uncovered the largest Velociraptor to date - and it measured five-and-a-half-feet tall, just like ours. So we designed it, we built it, and then they discovered it. That still boggles my mind." Spielberg was particularly pleased with the discovery of the "Utahraptor" because of the boost it gave to the velociraptors in his film. Spielberg's name was briefly considered for naming of the new dinosaur. In reality, "Velociraptor", like many other maniraptoran theropods, was covered in feathers.
