Fish - Fossilised animal - Lycoptera - 11 cm (No reserve price)

Fossil fish – Lycoptera sp. – 11 cm This specimen presents a complete and well-articulated skeleton of Lycoptera, a primitive bony fish belonging to the order Osteoglossiformes, which lived during the Early Cretaceous (about 120–130 million years ago). Lycoptera fossils typically come from lake deposits of the Yixian and Jiufotang Formations in Liaoning Province (northeastern China), worldwide renowned for the exceptional preservation of its fossils, often found in layers of fine volcanic ash that have preserved minute anatomical details. On the calcareous/marlstone matrix slab, the vertebral column, ribs, skull structure, and fins are clearly visible, with the brown-reddish coloration typical of iron mineralization that replaced the original organic tissues. Lycoptera is considered an index fish for dating the Liaoning deposits, being extremely abundant and widespread in these lacustrine ecosystems of the era of feathered dinosaurs. Includes: display case, ready for tabletop or shelf display.
