"Sunday crowds poured by thousands into American Museum of Natural History (...) to gaze upon and speculate about the huge skeleton of the brontosaurus which had the place of honor at the society tea held in dinosaurs room. The visitors all want to see the monster whose arrival had brought J. Pierpont Morgan from his Wall Street office to join the tea drinkers. A replica of one of the largest dinosaurs ever discovered is now on display at the museum".

Apatosaurus |
In 1990s, during the renovation of the fossil halls, the head of Apatosaurus ( a correct name for Brontosaurus) was replaced with cast of the skull from Pittsburgh’s Carnegie Museum. Apatosaurus skeleton with a detached skull was found just a few years after the Apatosaurus was first mounted, but for decades paleontologists disagreed over whether the skull belonged with the body.

A replica of one of the largest dinosaurs ever discovered was added to museum this January.
The biggest dinosaur ever exhibited at the museum and among the largest ever discovered stretches 122 feet long and rise nearly 20 feet to reach the ceiling. It is twice as large as the brontosaurus from 1904.
It is believed to have weighed, when walking the Earth roughly 100 million years ago, some 70 tons—as heavy as at least 10 African elephants.

The fossils were accidentally discovered in 2011 by a farm worker in a remote area in the Patagonian province of Chubut, some eight hundred miles south of Buenos Aires, Argentina. The worker spotted the tip of a massive fossil sticking out of the ground. Researchers started digging and in 2014 discovered the most complete skeleton of a titanosaur, a group of gigantic plant-eating dinosaurs that dominated the Southern Hemisphere beginning about 90 million years ago. After just one day of digging, paleontologists had uncovered more than 220 bones. One of the thigh bones measuring 7.8 feet in length.


Two dinosaur halls are located in the David H. Koch Dinosaur Wing of the museum. David H. Koch is an executive vice president and a board member of Koch Industries, Inc., which owns a diverse group of companies. A long-time philanthropist, Mr. Koch has given generously to a variety of organizations and programs.
He gave $20 million to the American Museum of Natural History in New York City establishing the David H. Koch Dinosaur Wing.
One of David Koch’s biggest hobbies, beyond his more general philanthropic pursuits, is paleontology. Dinosaurs are the things that interest him most. Koch caught the dinosaur bug at the age of 14, when his father took him and his twin brother, Bill, to visit the American Museum of Natural History. “I was just dazzled by the dinosaurs,” he told.
