英文摘要原文 / Original English abstract
Regenerating arms of crinoids represent direct evidence of nonlethal attacks by predators and provide an opportunity for exploring the importance of predation through geologic time. Analysis of 11 Paleozoic crinoid Lagerstätten revealed a significant increase in arm regeneration during the Siluro-Devonian. During this interval, referred to as the Middle Paleozoic Marine Revolution, the diversity of shell-crushing predators increased, and antipredatory morphologies among invertebrate prey, such as crinoids, became more common. Crinoid arm regeneration data suggest an increase in nonlethal attacks at this time and represent a causal link between those patterns, which implies an important role for predator-driven evolution.

摘要依据的主要发现 / Findings based on the abstract
对十一个特异化石群的分析显示，海百合腕再生在志留纪至泥盆纪增加；再生腕直接记录捕食攻击后的存活，而非只依赖防御形态推测。
Analysis of eleven exceptional fossil assemblages shows increased crinoid arm regeneration during the Silurian–Devonian. Regenerating arms directly record survival of predatory attacks rather than relying solely on defensive morphology.

摘要依据的结论 / Conclusions based on the abstract
该模式支持捕食增强在中古生代海洋演化变化中发挥重要作用。
The pattern supports an important role for escalating predation in Middle Palaeozoic marine evolutionary change.
