依据沉积学及遗迹学特征,豫西寒武系第二、三统馒头组共识别出固底遗迹化石11属15种,包括抓痕、爬痕类和潜穴类遗迹化石。节肢动物抓痕、爬痕类固底遗迹化石形成在沉积-水界面很浅处,保存为极为清晰、完整、精细的附肢痕迹,多形成于细粒的泥岩或粉砂质泥岩层面上,部分保存为上覆粗粒沉积物的底面铸型;潜穴类固底遗迹化石不发育外壁,以水平或近水平分布为主,保存有清晰的潜穴形态,潜穴表面发育精美的纹饰,充填物与围岩反差较大,被动充填上覆的粗粒沉积物或者聚集海底迂回的砂粒得以保存。发育遗迹化石的固底底质主要由沉积物长期或间歇性暴露和低的沉积物混合程度所致。
Based on sedimentology and relics, a total of 15 species of 11 genera of solid-bottom fossils are identified in the second and third member of the Cambrian of western Henan, including the scratches, the creeping marks and the burial fossils. Arthropod scratches and crawling marks Solid-bottomed fossils formed at shallow sediment-water interfaces and were preserved in extremely clear, complete and fine appendage traces that were mostly formed on finely divided muddy or silty mudstone surfaces, Part of which is preserved as the bottom mold of the overlying coarse-grained sediments; the burrows of the burrow-like bottom-fixed fossils do not develop outer walls and are mainly horizontal or near horizontal distributions, and have a clear shape of the latent holes, exquisitely developed ornamentation on the surface of the burrows, The contrast between the fillings and the surrounding rock is relatively large. Passive filling of overlying coarse sediments or roundabout gathers of seafloor can be preserved. The solid-bottomed sediments of developing fossils are mainly caused by the long-term or intermittent exposure of sediments and the low degree of sediment mixing.
