Peter Larson, President of the Black Hills Institute for Geological Research, is one of the most knowledgable paleontologists working today. His museum, located in the Hill City, South Dakota, boasts the highest concentration of dinosaur bones of any museum on earth.

While to many, Pete's known for his work as a leading expert in the study of theropods, particularly T. rex, he's also known for being at the center of one of the biggest controversies ever to rock the paleontological world -- the discovery, excavation, and FBI confiscation of the world famous T. rex known as "Sue." The saga is a story so unbelievable, it went on to become the focus of an Emmy-winning documentary, Dinosaur 13.

In this episode of the Backcountry Manifesto, we're on site at BHI, and with endless dinosaur specimens in around us, we talk all things paleontology, here compelling evidence in the "Juvenile T. rex or Nanotyranus?" debate, and get a first-hand account of the discovery, excavation, and confiscation of "Sue," as well as the resulting aftermath which saw Pete spend 18 months in federal prison.

In this episode, we talk about:

• Nanotyrannus and potential differences between T. rex


• Famous T. rex specimens


• The KT Boundary


• Sue, the T. Rex


• The ensuing legal battle with the Feds


• The BHI Museum
