Museum Quality Cambrian Trilobite Fossils – Changaspis – Guizhou, China For Sale

Up for sale is a fascinating trilobite fossil specimen from the Palang Formation of Guizhou Province, China, featuring small trilobites preserved together on a 2.7” (~6.9 cm) sedimentary matrix, with the largest trilobite measuring approximately 0.3” (~7.6 mm). The specimen is attributed to Changaspis elongata, an extinct trilobite from the Early Cambrian, approximately 510–520 million years ago. Trilobites were among the earliest successful groups of marine arthropods, inhabiting ancient seafloors hundreds of millions of years before the appearance of dinosaurs. Their distinctive segmented exoskeletons, divided into a central axial lobe and two lateral lobes, provide important evidence of early arthropod evolution. Changaspis is especially interesting to paleontologists because Cambrian trilobites help document the rapid diversification of complex marine animals during the Cambrian explosion. The Palang Formation of Guizhou is known for its early trilobite assemblages and provides an important record of life in the ancient seas of South China. The preservation of these tiny fossils together on their surrounding rock makes this an attractive educational and display specimen, offering a glimpse into an ecosystem more than half a billion years old. The exact fossil-bearing 2.7” matrix shown in the listing photographs is the specimen you will receive, making this an excellent addition for collectors of Cambrian fossils, Chinese trilobites, early arthropods, and ancient marine life.
