Rhamphorhynchus

Say it: RAM-foh-RINK-us  ·  Name means: “Beak snout”

⚠️ Not a dinosaur: Rhamphorhynchus was a pterosaur, a flying reptile. Pterosaurs were close cousins of dinosaurs, but their legs did not sit straight under the body in the dinosaur way and they evolved on a separate branch.

About Rhamphorhynchus

Rhamphorhynchus was a flying reptile with sharp teeth for catching fish and a long tail with a little diamond-shaped flag on the end. It was not a dinosaur!

Rhamphorhynchus was a long-tailed pterosaur from the Late Jurassic Solnhofen lagoons of Germany. Hundreds of beautifully preserved specimens, some with wing membranes and stomach contents, make it one of the best-studied pterosaurs.

How big was it?

Rhamphorhynchus: ~1.3 m wingspanPerson 1.7 m · School bus 12 m
Compare with other dinosaurs →

Drawn to scale next to a 1.7 m adult and a 12 m school bus (pterosaur size is wingspan).

Did you know?

  1. Rhamphorhynchus had a long tail with a diamond-shaped flap at the tip, like a kite tail!
  2. Its teeth pointed forward like a spiky fish trap.
  3. One fossil shows a Rhamphorhynchus that got caught by a big fish!
  4. Some fossils are so good you can see the shape of its skin wings.
  1. A famous Solnhofen slab preserves a Rhamphorhynchus tangled in the jaws of the large fish Aspidorhynchus, which may have grabbed it at the water's surface; both seem to have died and sunk together.
  2. Studies of growth stages showed that several 'species' of Rhamphorhynchus were really different ages of the same few species, with the tail vane changing shape as they grew.
  3. Specimens under ultraviolet light reveal details of the wing membrane, including stiffening fibres that helped control its shape.
  4. Its slow growth compared with birds suggests young Rhamphorhynchus may have been able to fly soon after hatching but took years to reach full size.

🐟 What did it eat?

Food: small fish, squid-like cephalopods.

Flew low over shallow lagoons and snapped up slippery fish with long, forward-pointing teeth that interlocked like a fish trap.

Clues scientists use: fish remains in the stomach area; needle-like, forward-pointing teeth; coprolites with fish bones.

Who might have hunted it: Aspidorhynchus.

Myth or fact?

✗ Myth: Rhamphorhynchus was an early bird.

✓ Fact: It was a pterosaur; birds come from feathered dinosaurs. Archaeopteryx, an early bird relative, lived in the same Solnhofen lagoons.
