Abstract

X-ray studies of slates from Bundenbach and Wissenbach (Lower and Middle Devonian, West Germany) revealed a surprising amount of pyritized soft parts of cephalopods and trilobites. The tentacles of cephalopods, the appendages, the intestinal tract, and the structure of the interior of facet eyes of trilobites (Phacops species and Asteropyge species) were found in a well-preserved state.

摘要

对来自德国下、中泥盆统的本登巴赫（Bundenbach）和威森巴赫（Wissenbach）板岩的 X 射线研究揭示了大量令人惊讶的已矿化的头足类和三叶虫软体部分。头足类的触手、附肢、肠道以及三叶虫（Phacops 种和 Asteropyge 种）面眼的内部结构都保存得非常完好。
