在吸血乌贼化石记录的空白中，唯一现存的物种（Vampyroteuthis innalis）与其早白垩纪形态相似的祖先分开了。虽然现存物种对低氧浓度的深海环境具有独特的生理适应性，但中生代吸血鬼形动物居住在陆表陆架上。然而，它们撤退到深海和缺氧栖息地的时间记录很少。在这里，我们记录了来自中帕拉提斯渐新世的中生代后吸血乌贼的第一个记录，以吸血鬼形态的剑兰为代表。我们将Necroteuthis hungarica归属于Vampyroteuthidae科，它将中生代loligosepiids与近代Vampyroteuthis联系起来。微古生物学、古生态学和地球化学分析表明，在盐度分层的Paratethys中央盆地中，Necroteuthis hungarica生活在底部缺氧、初级生产力高的深海环境中。因此，至少从渐新世开始，吸血乌贼就适应了深海、缺氧的栖息地。我们认为白垩纪和新生代早期的OMZs引发了它们的深海特化。一种吸血乌贼的新化石填补了它们化石记录中1.2亿年的空白。今天的吸血乌贼适应低氧深海环境，这个新标本提供了证据，表明吸血乌贼的深海特化可能是在白垩纪和新生代海洋缺氧带发育期间引发的。
A marked 120 My gap in the fossil record of vampire squids separates the only extant species (Vampyroteuthis infernalis) from its Early Cretaceous, morphologically-similar ancestors. While the extant species possesses unique physiological adaptations to bathyal environments with low oxygen concentrations, Mesozoic vampyromorphs inhabited epicontinental shelves. However, the timing of their retreat towards bathyal and oxygen-depleted habitats is poorly documented. Here, we document a first record of a post-Mesozoic vampire squid from the Oligocene of the Central Paratethys represented by a vampyromorph gladius. We assign Necroteuthis hungarica to the family Vampyroteuthidae that links Mesozoic loligosepiids with Recent Vampyroteuthis. Micropalaeontological, palaeoecological, and geochemical analyses demonstrate that Necroteuthis hungarica inhabited bathyal environments with bottom-water anoxia and high primary productivity in salinity-stratified Central Paratethys basins. Vampire squids were thus adapted to bathyal, oxygen-depleted habitats at least since the Oligocene. We suggest that the Cretaceous and the early Cenozoic OMZs triggered their deep-sea specialization. A new fossil of a vampire squid bridges a 120 million-year gap in their fossil record. Vampire squid today are adapted to low oxygen, deep sea environments and this new specimen provides evidence that the deep sea specialisation of vampire squid may have been triggered during the development of oxygen minimum zones in the oceans during the Cretaceous and Cenozoic.
