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 footprints and skeletal records often appear in different regions. However, some formations show closely related bones and footprints, all of which point to the same source. Reported the sauropod footprints (Brontopodus) from the upper part of the Lower Jurassic Yimen Formation of Tongbao Village, Tong’an Town, Panlias District, Panxi, Sichuan Province. Its geography and stratigraphy belonged to He Tongan dragon is very close. It is possible to ensure the connection between the trail and the trace maker, but more evidence is still needed. The Bolong footprint of Tongbao is the first discovery of the Jurassic sauropod footprints in the Panxi area. It also shows that in the early Jurassic, the primitive sauropods and the dry sauropods coexisted in southwest China.
