    摘要:

    通过详细追索调查，笔者等在禄丰盆地滑石板村一带发现大规模的恐龙足迹化石产地，产于白垩系下统马头山组下部紫红色钙粉砂质泥岩层面。足迹主要有蜥脚类、兽脚类、鸟臀类恐龙足迹等，足迹指示恐龙运动方向明显、足迹深度自南向北变化体现了古湖泊位于产地南部的古地理特征；鉴于足迹类型丰富、数量庞大、保存完整，为深入研究滇中地区早白垩世恐龙演化、生存环境及科普提供重要研究材料。

    Abstract:

    Through detailed investigation, a large- scale dinosaur footprint fossil production area was discovered in the area of Huashiban Village in the Lufeng Basin, which is located in the lower part of the Matoushan Formation of the Lower Cretaceous,on the purple red calcium sandstone layer and the lithic quartz sandstone layer. Methods: In this research, a suite of methods was utilized to study the fossils. These methods encompassed 1∶1000 geological profile measurement, 1∶100 trace fossil sketching, thin-section identification, fossil identification, and manual measurement.Result: The footprints mainly include sauropod, theropod, and ornithischian dinosaur footprints, etc. The footprints clearly indicate the direction of dinosaur movement, and the change in footprint depth from south to north reflects the paleogeographic characteristics of the ancient lake located in the south of the producing area.Conclusion: It provides important research materials for in- depth research on the evolution, living environment, and popularization of early Cretaceous dinosaurs in the central Yunnan region.
