Chinese Shandong Province Crafts - Set of 2 Chinese Antique-Style Paperweights These paperweights contain fossils of trilobites from the Paleozoic era, and are known in China as "bat stones" due to their resemblance to bats. While fossils of just the body or closed wings are seen, I believe fossils in this form, with the wings open, are rare. When lightly tapped together, they produce a high, pleasant sound. Size: 18cm x 3.4cm x 1.5cm - 1 piece Woven cloth case size: 20.5cm x 10.7cm x 3cm Weight: Approximately 270g / 1 piece (Please allow for slight variations as these measurements are approximate) They have been stored in a closet for many years without being used. Please refrain from purchasing if you are sensitive to items stored in a private home. We are also selling many other antiques and vintage items. We offer combined shipping discounts, so please take a look.
