These oysters inhabited shallow seas that once covered much of what is now Yorkshire, England. Gryphaea is easily recognized by its strongly curved, claw-shaped lower shell and smaller flat upper valve, giving the fossil its distinctive “toenail” appearance that inspired its unusual nickname.\u003c\/p\u003e\n\u003cp data-start=\"508\" data-end=\"1038\"\u003eThe name “Devil’s Toenail” comes from English folklore dating back centuries, when people believed the curved fossils were the petrified claws of the devil himself. In reality, Gryphaea fossils are extremely important to paleontologists because they provide insight into Jurassic marine ecosystems. Their thick calcitic shells preserve well in sedimentary rocks, and large fossil beds in the Yorkshire coast have yielded thousands of specimens that help scientists reconstruct the ancient seabed environments of the Jurassic seas.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eSmall\u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 3cm x 2cm x 1.5cm \u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 17g\u003cbr\u003e\u003cbr\u003e\u003cb\u003eMedium\u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 4.5cm x 3cm x 2.5cm \u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 48g\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eLarge \u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 5cm x 3.5cm x 3cm \u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 70g\u003cbr\u003e\u003cbr\u003e\u003cb\u003eX-Large \u003cbr\u003eApproximate Size of 1 Piece\u003c\/b\u003e: 6.5cm x 4cm x 3.5cm \u003cb\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/b\u003e\u003cb\u003eApproximate Weight of 1 Piece\u003c\/b\u003e: 140g\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003e\u003cstrong\u003eQuantity\u003c\/strong\u003e: 1pc\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003e\u003ci\u003eWe do our best to buy quality products- although not every rock is the same.
