Much of what we know about terrestrial life during the Carboniferous Period comes from Middle Pennsylvanian (~315–307 Mya) Coal Measures deposited in low-lying wetland environments^1,2,3,4,5. We know relatively little about terrestrial ecosystems from the Early Pennsylvanian, which was a critical interval for the diversification of insects, arachnids, tetrapods, and seed plants^6,7,8,9,10. Here we report a diverse Early Pennsylvanian trace and body fossil Lagerstätte (~320–318 Mya) from the Wamsutta Formation of eastern North America, distinct from coal-bearing deposits, preserved in clastic substrates within basin margin conglomerates. The exceptionally preserved trace fossils and body fossils document a range of vertebrates, invertebrates and plant taxa (n = 131), with 83 distinct foliage morphotypes. Plant-insect interactions include what may be the earliest evidence of insect oviposition. This site expands our knowledge of early terrestrial ecosystems and organismal interactions and provides ground truth for future phylogenetic reconstructions of key plant, arthropod, and vertebrate groups.

我们对石炭纪陆地生命的了解大部分来自于中宾夕法尼亚期（~315-307 Mya）煤系沉积在低洼湿地环境中^1,2,3,4,5 。我们对宾夕法尼亚早期的陆地生态系统知之甚少，这是昆虫、蜘蛛、四足动物和种子植物多样化的关键时期^6,7,8,9,10 。在这里，我们报告了来自北美东部瓦姆苏塔组的多种早期宾夕法尼亚痕迹和尸体化石 Lagerstätte（约 320-318 Mya），与含煤矿床不同，保存在盆地边缘砾岩内的碎屑基质中。保存完好的遗迹化石和尸体化石记录了一系列脊椎动物、无脊椎动物和植物类群 ( n = 131)，具有 83 种不同的叶子形态类型。植物与昆虫的相互作用可能是昆虫产卵的最早证据。该网站扩展了我们对早期陆地生态系统和生物体相互作用的知识，并为未来关键植物、节肢动物和脊椎动物类群的系统发育重建提供了基础事实。
