In short: keep fossils dry, stable and out of strong direct sunlight, dust them with a soft dry brush, and never wash them with water or cleaning products.
Where to display a fossil
- Indoors, away from damp: bathrooms, basements and kitchens are poor choices.
- Stable temperature: avoid placing fossils above radiators, next to heaters or near air-conditioning vents.
- Limited direct sunlight: strong sun over years can fade colours and heat the specimen.
- Secure surface: large skulls and jaws belong on a stable, level base or their stand, away from busy walkways and pets.
How to clean a fossil
- Use a soft, dry brush, such as a clean make-up or paint brush.
- Brush gently in one direction to remove dust.
- For hard-to-reach areas, use a gentle puff of air from a hand blower.
- Do not use water, soap, polish, vinegar or household cleaners.
Many fossils, especially from phosphate deposits, are porous. Liquids can soak in, weaken the material or dissolve adhesives used in preparation.
Handling
- Lift by the base or the thickest, strongest part.
- Never lift a skull or jaw by its teeth.
- Use two hands, and two people for large pieces.
- Clean, dry hands or cotton gloves help avoid skin oils.
Specific tips
Fossil teeth
Store small teeth in padded boxes or display cases so they do not knock against each other.
Trilobites
Spines are delicate. Keep spiny trilobites in a closed case to protect them from dust and accidental knocks.
Large skulls, jaws and skeletons
Check the stand and mounts from time to time. For very large mounted specimens, professional installation is recommended.
Storage and moving
Wrap each fossil in acid-free tissue, then bubble wrap, and pack it in a rigid box with padding on all sides. Never stack heavy items on top.
