GEOFOSSILES

“David Guery has traveled far, as has his business.”

From Colorado Springs

Geofossiles is a well-known fossil vendor that specializes in offering a wide variety of fossils, minerals, and related geological specimens. They are recognized for their extensive collection of high-quality fossils sourced from various locations around the world.

Geofossiles caters to collectors, enthusiasts, educational institutions, and museums, providing an array of specimens ranging from ancient vertebrates and invertebrates to plant fossils and geological curiosities. Their offerings often include fossils from iconic geological formations, such as trilobites, ammonites, dinosaur bones, and fossilized plants. Geofossiles is renowned for its commitment to authenticity, quality, and customer satisfaction, making it a trusted source within the fossil and mineral community.

Official Website

David Guery, 41, was born and raised in Sedan, France, and has been selling fossils and other earth-embedded objects for the past 13 years. He attended his first gem show with his grandpa in France when he was 8 years old and took joy and relaxation from uncovering fossils from their casts.

What started as a hobby for him became a job after he left his factory position.

[…]

Finding trusted suppliers such as the one in South Dakota is crucial for the Guerys’ business. Much of David’s tenure as a fossil seller has been spent building and maintaining relationships with miners and lapidaries (people who cuts and polishes gems) from around the world, particularly Madagascar and Morocco.

He has spent weeks at a time traveling to hand pick the pieces and stones he wants. ” – Colorado Springs Gazette
