摘　　要：恐龙足迹和骨骼的记录往往出现在不同的地区。然而,一些地层显示了关系紧密的骨骼和足迹,它们都指向同一个来源。报道了来自四川省攀西地区会理县通安镇通保村下侏罗统益门组中上部的蜥脚类足迹(雷龙足迹Brontopodus),其地理和地层归属均与真蜥脚类的何氏通安龙极为接近。通保足迹与造迹者的关联是可能的,但目前还需要更多的证据。通保的雷龙足迹是攀西地区首次发现侏罗纪的蜥脚类足迹,这也表明,在早侏罗世,原始蜥脚类和基干蜥脚型类共存于中国西南地区。Dinosaur track and bone records often occur at different locations. However, a few formations show a close correspondence between bones and tracks that correspond to likely trackmakers. In this paper, the authors report sauropod tracks （ Brontopodus） in very close geographic and stratigraphic proximity to the type locality of the eusauropod Tonganosaurus hei in the middle-upper parts of the Lower Jurassic Yimen Formation in Tongbao Village, Huili County, Panxi region of Sichuan Province. This Huili track-trackmaker correlation is possibly existent, but still needs more evidence to confirm. As the first Jurassic sauropod tracks found in the Panxi region, the Tongbao Brontopodus tracks have provided evidence indicating coexistence of primitive sauropod and basal sauropodomorphs in Southwest China during Early Jurassic.
