乍看像埋在地下的破碎麻布,由麻布拼凑成一胖一瘦的两个布娃娃,相互嬉戏,童趣盎然。这是一枚难得的雨花石中的苔藓虫化石。雨花石中化石极少,目前已发现的有(虫竹廷)化石、海百合化石、鹦鹉螺化石、螺化石、珊瑚化石、辉木化石和苔藓虫化石等等。雨花石中的化石与一般化石是两个不同的概念。雨花石中的化石虽然也是由沉积岩形成的,但它的石化程度高,有的已硅化,相当坚硬,原岩破碎后,经水流搬迁,磨砺成卵状
At first glance, like the broken linen buried in the ground, put together by the linen into a fat and a thin two dolls, playful, childlike. This is a rare boulder fossil in the stone. There are very few fossils in the stone. So far, we have found fossils of pest bamboo, fossil sea lilies, nautilus fossils, coral fossils, coral fossils, feldspar fossils and bryozoa fossils. Fossils in the stone and the general fossils are two different concepts. Although the fossils in the stone are also formed by sedimentary rocks, it has a high degree of petrification and some have been silicified and quite hard. After the original rocks are broken, they are removed by water flow and ground into eggs
