Fossil specimens of this quality require no special maintenance — wipe clean with a soft, dry cloth or a soft brush for the textured surface areas. Avoid water immersion and harsh chemical cleaners. Keep away from direct prolonged sunlight to preserve any original shell coloration. Handle with appropriate care when moving — at 3.6 lbs, this is a substantial object, and the fossil surface, while durable, is irreplaceable.\u003c\/p\u003e","brand":"Rare Earth Gallery","offers":[{"title":"Default Title","offer_id":43162441941081,"sku":"8336","price":1499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9096\/0473\/files\/rn-image_picker_lib_temp_17394d46-e16a-43eb-985a-4722640040a3.jpg?v=1773945801"},{"product_id":"shark-tooth-fossils","title":"Shark Tooth Fossils","description":"\u003cp\u003e\u003cstrong\u003eDescription:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSharks have inhabited the oceans for approximately 450 million years, making them older than the dinosaurs.
