Barnum Brown
In early 1923, notable fossil prospector, Barnum Brown (famed for discovering the first "Tyrannosaurus rex" skeleton) traveled with his wife Lilian Brown to Yangon, the capital of Myanmar. Brown focused his fossil prospecting along areas of Pondaung Sandstone. In the outskirts of Mogaung town, he identified a mandible with three teeth (right). He did not recognise the significance of his find until 14 years later, when Edwin H. Colbert identified the fossil as a new species of primate and the earliest known anthropoid in the world.
