Trilobite fossils from Yanzishi Fossil, formed in the Paleozoic Late Cambrian, are one of the rare paleontological fossils in China about 500 million years ago. Trilobites, arthropods that grew in seawater at that time, formed fossils due to changes in the crust. The discovery of trilobite fossils in Shandong provides a scientific basis for scientists to study the evolution and development of Shandong paleontology, and also more strongly confirms the scientific research conclusion that Shandong and its surrounding areas were oceans in the middle and early Paleozoic of Cambrian. Therefore, the paleontological trilobite fossils have certain scientific research value. ,
It is extremely rare for the remains of ancient creatures hundreds of millions of years ago to become fossils. According to scientists' estimation, after 10,000 kinds of living things die, only one may become a fossil, and most of these fossils are buried deep in the stratum, and only a few fossil rocks near the surface can be found by accident. Most of the fossils found are incomplete fragments of organisms, so it is difficult to identify the whole picture of their morphology or characteristics, so it is difficult to find fossils that can determine their names and generations. Shandong trilobite fossils are not deeply buried, easy to collect and complete in form, which is worthy of being a treasure of China and has high collection value. .
Yanzishi Fossil fossils can be made into treasures of the study, such as inkstone, paperweight, pen holder and inkpad box, and can also be made into craft decorations such as screens, vases and fans. Simple and elegant modeling, fresh and elegant style, following the shape, combining form with art, unique charm. People call it "a rare natural art treasure", which is deeply appreciated by some calligraphers, artists and intellectuals and becomes a good gift for relatives and friends. Fan Ceng, a famous painter and calligrapher, once wrote a poem about Yanzishi Fossil's fossil handicrafts. The poem reads: "Fossils have sunk for hundreds of millions of years, and swallows have become disabled. Collapse, no fire, it created a chaotic soul. "
