How big is Rhamphorhynchus?
1.25 米!
A genus of long-tailed pterosaurs from the Late Jurassic (about 150 million years ago). With a wingspan of approximately 3–6 feet (1–2 meters), Rhamphorhynchus had a lightweight body, long jaws with sharp teeth, and a distinctive diamond-shaped vane at the end of its tail. It likely fed on fish, using its long teeth to snatch prey from the water while in flight.
