Barnum Brown

Barnum Brown (February 12, 1873 – February 5, 1963), commonly referred to as Mr. Bones, was an American paleontologist. Named after the circus showman P.T. Barnum, he discovered the first documented remains of Tyrannosaurus rex during a career that made him one of the most famous fossil hunters working from the late Victorian era into the early 20th century.

Fossil dinosaur expeditions

Sponsored by the American Museum of Natural History (AMNH), Brown traversed the country bargaining and trading for fossils. His field was not limited to dinosaurs. He was known to collect or obtain anything of possible scientific value. Often, he simply sent money to have fossils shipped to the AMNH, and any new specimen of interest often resulted in a flurry of letters between the discoverer and Brown.

After working a handful of years in Wyoming for AMNH in the late 1890s, Brown led an expedition to the Hell Creek Formation of Southeastern Montana. There, in 1902, he discovered and excavated the first documented remains of Tyrannosaurus rex.
