这里报道的恐龙足印化石是本省九曲湾铜矿在1979年发现的,后由我队蔡和气等同志采集。标本采自湘西北沅麻盆地辰溪县九曲湾铜矿的红色地层中,约3平方米,已送交湖南省地质博物馆保存。根据采集者的野外追索、对比,化石产出层位应归于上白垩统小洞组的顶部。该地区的地层顺序由上而下是: 上白垩统锦江组: 为一大套砖红色泥质粉砂岩,粉砂岩,细砂岩,夹棕黄、黄绿、青灰、灰白等杂色含砾细至粗砂岩,产有比较丰富的介形类化石、恐龙蛋化石碎片和植物化石碎
The dinosaur footprints reported here were discovered by the Jiuqu Wan Copper Mine in the province in 1979 and collected by my team, Cai Heqi and other comrades. The specimen was collected from the red stratum of the Jiquwan Copper Mine in Chenxi County, Yuanmian Basin, northwestern Hunan Province, about 3 square meters and was sent to the Hunan Provincial Geological Museum for preservation. According to the collectors’ field reclamation and contrast, the fossil output layer should be attributed to the top of the Upper Cretaceous cave group. The sequence of the strata in the area is from top to bottom: Upper Cretaceous Jinjiang Formation: a large set of brick-red muddy siltstone, siltstone, fine sandstone, yellow-green, yellowish green, To coarse sandstone, producing a wealth of mesogenic fossils, dinosaur egg fragments and fossil plant fragments
