国际研究团队在美国怀俄明州发现了一种距今约1.6亿年的新菊石物种，命名为Wyoteuthis linsterorum 1。这种侏罗纪生物以其异常粗壮的桶形身躯而与众不同，是迄今为止已知最厚的菊石 1。其内骨骼长度约10厘米、宽度达6厘米，整体生物体长度估计约60厘米 1。
该研究由来自美国、英国和新西兰的国际研究团队合作完成，成果发表在《古生物论文》期刊上 1。第一件标本由Burkhard Pohl博士在1990年代后期发现 1，第二件标本则由Cliff Linster在2019年捐赠给怀俄明恐龙中心 1。研究人员采用CT扫描技术对该生物的内部结构进行了分析 1。物种名中的"linsterorum"旨在纪念Cliff Linster及其家族对该研究的贡献 1。
An international research team has identified a remarkable new cephalopod species from the Jurassic period, expanding our understanding of ancient squid diversity. The newly described organism, named Wyoteuthis linsterorum, was discovered in Wyoming's Sundance Formation and lived approximately 160 million years ago 1. What makes this creature exceptional is its highly unusual morphology: it possessed an exceptionally stout, barrel-shaped body with an internal skeleton measuring roughly 10 centimeters in length and 6 centimeters in width, making it the thickest cephalopod shell ever documented 1. The complete organism is estimated to have reached about 60 centimeters in total length 1.
The discovery represents a collaborative effort by paleontologists from the United States, United Kingdom, and New Zealand, with findings published in the journal Papers in Palaeontology 1. The first specimen was identified in the late 1990s by Dr. Burkhard Pohl, while a second example was donated to the Wyoming Dinosaur Center by Cliff Linster in 2019 1. The species name honors Linster and his family's contributions to paleontological research 1. Researchers employed CT scanning technology to analyze the creature's internal structure, revealing anatomical details that distinguish Wyoteuthis linsterorum as a morphologically distinct form among known Jurassic cephalopods 1.
