Caring for Your Fossil Collection: Preservation Tips from the Experts
Whether you’re a seasoned fossil collector or just starting out, one thing is clear: fossils are irreplaceable treasures of Earth’s deep history. But without proper care, even the most stunning trilobite or ammonite can suffer damage over time. Here’s how to preserve your collection and protect your investment.
1. Keep Fossils Out of Direct Sunlight
Ultraviolet light can cause discoloration, cracking, and the breakdown of mineral content. Display your fossils in shaded areas or inside UV-filtered glass cases.
2. Control Humidity and Temperature
Rapid changes in humidity or temperature can cause fossils to crack or flake. Aim for a stable environment, ideally between 45–55% humidity and a moderate room temperature (18–22°C / 65–72°F).
3. Handle with Care—Preferably with Gloves
Oils and sweat from your hands can damage fragile fossils over time. For best practice, wear nitrile or cotton gloves when handling delicate specimens, especially those with matrix or open sutures.
4. Avoid Harsh Chemicals
Never clean fossils with bleach, acids, or household cleaners. These can irreversibly damage surfaces. Instead, use a soft brush or compressed air for dusting. For more stubborn residue, a damp cloth with distilled water is safe for most specimens.
5. Store Properly with Support
For loose or delicate fossils, use padded boxes or foam-lined drawers. Label everything clearly and avoid stacking pieces to prevent stress fractures.
6. Use Display Stands That Support the Structure
For fossils like ammonites, trilobites, or fossil teeth, use custom stands or cushioned mounts that distribute weight evenly and prevent tipping or warping over time.
7. Seal Fragile Fossils with Paraloid B-72 (Optional)
For extremely fragile specimens (especially Moroccan fossils from soft matrix), conservators use Paraloid B-72—a reversible, museum-grade acrylic resin—to stabilize cracks or flaking. It should be used carefully and sparingly.
Bonus Tip: Keep Fossil Records
Document each specimen with its scientific name, age, location, and any treatment applied. Not only does this increase its scientific and resale value, but it also helps you track its condition over time.
