摘要
简要报道湘西麻阳上白垩统麻阳含铜建造中新近发现的一种巨型痕迹化石。该化石为圆柱状或椭圆柱状,直或略曲,不分叉,不分节,潜穴壁平滑,直径10cm左右,保存长度3m左右,初步定名为"巨型漫游迹(Planolitesgigassp.nocv)"。这一发现对于痕迹化石及麻阳含铜建造的研究具有一定意义.
A giant trace fossil has been discovered in the Mayang copper-bearing formation(K_2 ) inwestern Hu'nan,China.The burrow is preserved in the thin to medium-bedded pebble-bearing silt-tofine-sandstone,which was formed in the flood plain, In the field,two specimens,smooth,un-branched,continuous,circular or slightly elliptical in shape,have been examined in cross section,di-ameter of about 10 cm and more than 3 m long。
