This week, Clay Jenkinson’s conversation with Dr. Grant Zazula, a Yukon paleontologist. Nothing seemed to have fascinated Thomas Jefferson more than the mammoth and the mastodon, to the point that his detractors ridiculed his obsession. Jefferson convinced Meriwether Lewis and William Clark to dig up mastodon bones at Big Bone Lick, Kentucky. Grant Zazula has had spectacular success gathering mammoth bones exposed by placer gold mining in the Yukon. Most recently, he was able to collect an intact mummified baby mammoth, which delighted and stunned the paleontological community. Clay had the opportunity to hear Dr. Zazula’s amazing story of scientific fascination and paleontological success.
