Trex Agate Shop

Trex Agate Shop was established over 65 years ago by the Cliff and Marion Trexler family. Marion (Trexler) Brandvold also discovered the first North American baby dinosaur fossils in 1978.

At one time, Trex Agate was the largest producer of Montana agate jewelry in the area. The shop is now open from mid May through September and features fossils, rocks, artifacts, jewelry and a fine assortment of crystals and gift items. Dinosaur displays are a distinctive attraction.

As Marion remembers her experiences through the years, some of her fondest memories are of the individuals and families who visited the rock shop and of her discovery of the baby dinosaur fossils. Since that discovery, she has been featured in several national magazines and on worldwide television programs. Come and visit Marion for a unique shopping experience.
