At Lindgren Fossils, preparation is both a science and an art. Every specimen is carefully examined and prepared under high magnification using specialized equipment and decades of experience. The goal is not simply to expose a fossil, but to reveal and preserve every possible detail while maintaining the integrity of the original specimen.


The images below document the gradual preparation of a Green River Formation garfish. Using precision micro air abrasion and specialized hand tools, layers of limestone are carefully removed to reveal the fossil while preserving every possible anatomical detail. This meticulous process often requires dozens of hours of patient, highly skilled work.






Watch a Green River Formation garfish being prepared under magnification using precision micro air abrasion. This close-up view demonstrates how tiny layers of limestone are removed while preserving delicate fossil detail—a process that requires patience, precision, and years of experience.
