Lagerst?tten, exceptionally preserved fossil assemblages in the geological record, hold great scientific value for studying the fine morphology and anatomical structures of fossil organisms, as well as paleoecology, paleophysi ology, and biological evolution. Since the 1970s, research on Lagerst?tten has experienced phased growth, culminating in significant advancements in recent years. This paper reviews the spatial and temporal distribution, current research status, and scientific significance of Triassic Lagerst?tten, which have been discovered in both marine and terrestrial deposits, primarily located in China, Europe, and North America, spanning a broad timeframe from the Early to Late Triassic. These Lagerst?tten have played a crucial role in elucidating the early Mesozoic biota, the recovery and radia tion processes of life following the Permian-Triassic mass extinction, the establishment of modern-type marine eco systems, and the Mesozoic marine and lacustrine revolutions. Although a substantial number of Lagerst?tten have been discovered in China – 10 out of the 25 Lagerst?tten documented in this paper – the level of research remains compara tively lower than that of the well-studied European regions. Therefore, Lagerst?tten from China hold great potential for future research, particularly in uncovering new biological groups and their ecological significance. Enhancing related studies will contribute significantly to understanding global Mesozoic biological evolution.
