Aspidorhynchus acutirostris
Aspidorhynchus acutirostrisAspidorhynchus acutirostris was a slender, torpedo-shaped predatory fish that prowled the warm, shallow seas and lagoons of Late Jurassic Europe. Equipped with heavy ganoid scales, a symmetrical tail fin, and an elongated upper jaw forming a sharp rostrum, it darted forward with sudden bursts of speed to ambush smaller aquatic prey. Famous fossil specimens from the Solnhofen Limestone reveal that it occasionally snared low-flying pterosaurs such as Rhamphorhynchus, dragging both predator and prey to the anoxic seafloor.

- Extinct prehistoric species known only from fossil remains.
Responsible observation
- Museum Viewing: Examine articulated Solnhofen fossils to observe the needle-like rostrum and dense ganoid scales.
- Fossil Identification: Look for the characteristic overhanging upper jaw, which easily distinguishes it from other Jurassic ray-finned fish.
