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".
Two Medicine Dinosaur Center
The Two Medicine Dinosaur Center is a 501(c)(3) non-profit and educational institute located in Bynum, Montana that opened in 1995. It is part of the Montana Dinosaur Trail and home to a skeletal model of what is believed to be the world's largest dinosaur, a seismosaurus.
The center also houses the first baby dinosaur bones collected in North America - the original discovery reported by paleontologist John R. Horner.
