Modern burrowing organisms feed on microbial organic matter in matgrounds near hot springs on the margins of Lake Bogoria, a saline alkaline lake in the Kenya Rift Valley. The burrowers produce a low‐diversity trace assemblage similar to those produced by undermat miners during the Ediacaran–Cambrian transition. Despite obvious differences in body plans and phylogenetic affinities, these modern animals feed on microbes in similar ways to those inferred for primitive bilaterians. With increasing distance from hot‐spring vents, outflow channels and adjacent matgrounds, the diversity and depth of the traces increase and mixgrounds become dominant. This modern extreme environment gives clues for interpreting the heterogeneous early Cambrian seafloor, with: (1) the restriction of ‘pre‐agronomic revolution’ matground substrates; and (2) expansion of adjacent ‘post‐agronomic revolution’ mixground areas.

肯尼亚裂谷波哥利亚湖matmats的生物扰动：解释早期寒武纪海底的异质意义

现代穴居生物在肯尼亚裂谷的盐碱湖博古里亚湖边缘温泉附近的温泉中以微生物有机物为食。穴居人产生的低多样性痕迹组合与埃迪卡拉安-寒武纪过渡时期地下采石工产生的相似。尽管在身体计划和系统发育亲和力方面存在明显差异，但这些现代动物以与原始双边生物推断的方式相似的方式以微生物为食。随着与温泉通风口，流出通道和邻近地基之间距离的增加，迹线的多样性和深度也随之增加，并且混合地层成为主导。这种现代的极端环境为解释异质的寒武纪早期海底提供了线索，包括：（1）对“农学前革命”基质的限制；
