The discovery of Tyrannosaurus rex:

In 1902, Barnum Brown, an American dinosaur fossil collector, discovered a giant carnivore in Hale Creek, Montana, USA. Sexual animal skeletons while he was on staff at the National Museum of American History. Over the next two summers, he excavated the skeleton from the solid sandstone. Since the bones were quite heavy, he built a special sled pulled by horses and transported the bones to a nearby road. What he found was the first Tyrannosaurus rex skeleton.

In 1910, an expedition team led by Barnum Brown began large-scale collection in the Red Deer River Canyon in Alberta, Canada. Brown found extremely well-preserved skeleton fossils of Styracosaurus, Helminosaurus and Centrosaurus there, as well as some dinosaur skin fossils.

In the New York Museum, Brown's boss Osborne couldn't wait to make the animal he named Tyrannosaurus rex public. While installing the skeleton, Brown and Osborne used models to reconstruct the Tyrannosaurus rex. However, they could not assemble the two-ton bones into the image they had in mind - a "behemoth as nimble as a bird". They had to assemble him into an upright and dull appearance.
