软体乌贼是现代海洋生物的主要组成部分，但由于化石记录不完整，人们对它们的进化知之甚少。
研究组通过“数字化石挖掘”技术提供了一个全面的鱿鱼进化历史，揭示了一个新的最大的40个物种的250多个喙化石，这些表明乌贼起源于1亿年前，并迅速扩散。他们的数据表明，从重壳、缓慢移动的头足类动物到软体动物的根本转变并不是由白垩纪末期（6600万年前）的大灭绝造成的。早期乌贼已经形成了大量种群，其生物量超过了菊石类和鱼类。它们是现代海洋生态系统的先驱，是聪明、快速的游泳者。

Abstract: The evolution of soft-bodied squids, which provide a major part of the biomass in modern oceans globally, is poorly understood owing to their patchy fossil record. We provide a comprehensive evolutionary history of squids through “digital fossil-mining” techniques, revealing a new lagersttte. The more than 250 fossil beaks of 40 species show that squids originated and rapidly radiated by 100 million years ago. Our data suggest that the radical shift from heavily shelled, slowly moving cephalopods to soft-bodied forms did not result from the end-Cretaceous mass extinction (66 million years ago). Early squids had already formed large populations, and their biomass exceeded that of ammonites and fishes. They pioneered the modern-type marine ecosystem as intelligent, fast swimmers.
