Terrestrial ecosystems from the Lower Cretaceous of Europe and bonebeds formed in swampy environments are poorly known. The Berriasian‐early Valanginian Angeac‐Charente site in France represents an example of both. Nine field campaigns have yielded thousands of fossils of over a hundred taxa, including 16 taxa from vertebrate macroremains with numerous trample and crocodile bite marks; 22 taxa from the abundant vertebrate microremains; >10 vertebrate coprolite morphotypes with plant and vertebrate inclusions; abundant sauropod and stegosaur tracks including some preserved in ‘4‐D’; termite coprolites; mollusc moulds; ostracods and plants, including coniferous wood, cones, leaves and cuticle fragments, charophytes and pollen. The richness, diversity and preservation of the fossils qualify the site as a fossil‐Lagerstätte. The site represents a ‘snapshot’ into a Lower Cretaceous ecosystem. This is supported by REE analyses of biogenic apatite and sediment samples, the fossils being found in a single stratigraphical interval and the record of sedimentological and taphonomic ‘frozen scenes’. The Angeac‐Charente bonebed is highly diverse, dominated by an ornithomimosaur taxon, and contains both macro‐ and microfossils. This indicates a complex formation, likely primarily influenced by ecological and biologic processes, but also significant physical processes. These include crocodyliform predation and/or scavenging on turtles, ornithomimosaurs and fishes; probable mass mortality occurrence of an ornithomimosaur herd; possible social behaviour of stegosaurs; limited hydraulic transport of most sauropod bones and intense dinoturbation.

来自法国的下白垩统Lagerstätte：Angeac-Charente脊椎动物组合的植物学概述

来自欧洲下白垩统的陆地生态系统和在潮湿环境中形成的骨床鲜为人知。法国的Berriasian-早期Valanginian Angeac-Charente遗址就是这两个例子。九次野外运动产生了上百种生物分类的数千种化石，其中包括16种来自脊椎动物大残骸的生物，其中有大量践踏和鳄鱼咬痕。来自丰富的脊椎动物微遗物的22类群；具有植物和脊椎动物包裹体的> 10种脊椎动物coprolite形态型；丰富的蜥脚类和剑龙踪迹，包括保存在“ 4-D”中的一些踪迹；白蚁proprolites; 软体动物模具；兽脚类和植物，包括针叶木材，视锥细胞，叶子和表皮碎片，生叶植物和花粉。化石的丰富性，多样性和保存性使该地点成为化石-Lagerstätte。该站点代表了下白垩统生态系统的“快照”。这通过对生物磷灰石和沉积物样品的REE分析，在单个地层间隔中发现化石以及沉积学和大气学“冻结场景”的记录来支持。Angeac-Charente的骨床种类繁多，以兽龙类生物分类为主，并包含宏观和微化石。这表明形成复杂，可能主要受到生态和生物过程的影响，但也受到重要的物理过程的影响。这些包括对鳄龟的捕食和/或对乌龟，兽龙和鱼类的清除；甲龙群可能发生的大量死亡；剑龙可能的社交行为；大部分蜥脚类动物骨骼的水力运输受到限制，并且强烈进行了非脊突运动。
