Thomas E. Lindgren

An internationally recognized fossil expert, particularly with regard to the Green River Formation fossils of Wyoming, Thomas E. Lindgren’s career has integrated the worlds of scientific and commercial paleontology. 

Mr. Lindgren has secured fossil specimens for world-renowned institutions such as The American Museum of Natural History in New York, The Field Museum in Chicago, Museums of Scotland, The Denver Museum and the Smithsonian. Additionally, his donations of fossils and artifacts to several educational institutions and museums illustrate his commitment to worldwide appreciation of the Earth’s paleontological treasures.


Mr. Lindgren has served as a fossil appraiser and professional witness for the U.S. State Department at The Haag, Netherlands. He has appraised numerous important fossils and fossil collections for individuals and institutions.


On a commercial plane, Mr. Lindgren has offered and sold fossil specimens on the international auction market since 2002, and to discerning private collectors at international fossil and mineral shows since the mid-1980’s. He has appeared on numerous television programs such as Pawn Stars, Designing for the Sexes, Christopher Lowell, QVC and Cash and Treasures


Mr. Lindgren's passion for natural history grew from a high school field trip in which student labor was instrumental in saving a Native American archaeological site from the ravages of erosion due to dam development. Over a nearly thirty-year period as a self-taught paleontologist, he has acquired in-depth field and lab experience in fossils, as well as extensive knowledge in the valuation of fossils, minerals and a wide variety of natural history items.


Mr. Lindgren has established an extensive worldwide network of contacts through which he is constantly informed of the availability of new and interesting fossil and mineral specimens, materials and products. GeoDecor represents the culmination of Thomas Lindgren’s life’s work, offering the world’s most desirable fossil and mineral specimens to designers, collectors and museums. 


Mr. Lindgren is a member of the prestigious Society of Vertebrate Paleontology and of the Association of Applied Paleontological Sciences. He is a guest lecturer at the University of Arizona Department of Geosciences.
