Xinlong Formation, Geological formation in Guangxi, China
The Xinlong Formation is a geological rock sequence in Guangxi composed of sandstone, mudstone, conglomerate, and marl layers stacked upon one another. These deposits from the Early Cretaceous hold fossils of multiple dinosaur genera.
This rock sequence formed during the Early Cretaceous approximately 120 to 100 million years ago, recording a time when dinosaurs lived in this region. Scientists have uncovered remains of several species here that shape our understanding of that ancient fauna.
The formation represents a significant research site for Chinese geologists and international scientists studying Early Cretaceous vertebrate paleofauna.
Access to the formation requires special permits and coordination with local institutions because the site lies in remote areas. Visitors should contact local research centers to clarify access rules and necessary preparations.
Among the fossils found here is Liubangosaurus hei, a species known chiefly through its distinctive spinal vertebrae. This particular structure helps researchers distinguish this genus from other dinosaurs of that period.
