Size：60cm*30cm Scientific name: Peipiaosteus sp. A pair of sturgeon fossils, the bodies are relatively well-preserved, showing characteristics of sturgeonids such as a long, pointed snout, a posterior dorsal fin, and a heterocercal tail fin. Sturgeon are an ancient group of bony fish with cartilaginous skeletons, bony plate-like body surface structures, and a unique tail fin morphology, and are considered one of the most primitive groups of fish. This specimen is presented symmetrically, making it highly visually appealing.
