Bruce R. Erickson (born 1933) is an American paleontologist and Chair of Paleontology at the Science Museum of Minnesota. During the course of his lifetime and his 55 years as a paleontologist, he has "collected about a million specimens" and discovered fifteen new types of plants and ancient animal species. His collection includes "a triceratops skeleton" that he discovered in 1961 at the Hell Creek Formation that is considered to be "one of the rarest in the world". His research has focused almost entirely on the Paleocene era in history.
In the 1960s, Erickson spent his time investigating "crocodile and champsosaur fossils in Alberta, Canada". It was there that he discovered "the oldest known alligator." He was also investigating crocodile fossils in South Africa during the same decade.
The main focus of his career has been on an area in western North Dakota, where he discovered that the badlands there had once been a river and swamp, "58 million to 60 million years ago". Afterward, the place became known as the Wannagan Creek site. Just from this area alone, Erickson and the rest of his team have discovered thousands of fossils since they began digging in 1970. The interest in the site began in 1970 after Erickson received a shoe box full of bone sent to him by a rancher's wife. The bones in the shoe box were found to be from six different crocodiles of Paleocene origin. It was this revelation that caused him to go and investigate the site.
Later in his career, he was involved in a "seven-year research project" at the Chandler Bridge Foundation in the late 1990s that resulted in finding the skeleton of a "28-million-year-old whale".
