Species Name: Lycoptera davidi
Geological Age: Early Cretaceous (approx. 125 million years ago)
Locality: Western Liaoning (Jehol Biota / Yixian Formation)
Specimen Characteristics:
Multiple Individuals (Associated Assemblage): This split-slab specimen preserves multiple Lycoptera individuals, exhibiting a classic mass-mortality burial pattern indicative of schooling behavior.
Typical Morphological Features: Spindle-shaped body, heterocercal (asymmetrical) tail fin, posteriorly positioned dorsal fin, and clearly visible vertebral and rib structures—all characteristic of Lycoptera.
Preservation: Split slab (part and counterpart); skeletal details and fin rays are fully preserved with high contrast.
Contains repaired cracks; please refer to the images.
