Rhamphorhynchus was a flying reptile that lived in the Late Jurassic. It had a very long tail with a diamond-shaped flap at the tip. It used its needle-like teeth to catch slippery fish.1 2

Its tail was stiffened with ligaments and ended in a diamond-shaped rudder, which may have helped it steer while flying.1 2

Rhamphorhynchus had no teeth at the very tip of its beak, but the rest of its beak held many forward-angled teeth that interlocked to trap fish.1

Fossils of Rhamphorhynchus often show impressions of soft parts, including wing membranes and fuzz-like pycnofibers.1

It probably swam and launched from the water like modern birds, not just flew over the waves.1

Rhamphorhynchus lived about 150 to 148 million years ago, during the late Jurassic Period.1

?How big was Rhamphorhynchus?

Most adults had a wingspan of about 1 metre (3.3 feet), but the largest known specimen reached about 1.8 metres (5.9 feet) across. A huge fragmentary fossil may have had a wingspan of over 3 metres (10 feet).1 5

?What did Rhamphorhynchus eat?

It mainly ate fish and squid-like animals called cephalopods. Fossil stomach contents and droppings often contain fish and cephalopod remains.1 2

?Could Rhamphorhynchus swim?

Yes, it probably swam and launched from the water like modern birds. Its broad feet and body shape suggest it was good at swimming.1

?When did Rhamphorhynchus live?

It lived during the Late Jurassic Period, about 150 to 148 million years ago.1 2

?Was Rhamphorhynchus a dinosaur?

No, it was a pterosaur, a flying reptile that is not a dinosaur. Pterosaurs are close cousins of dinosaurs.1 2

?Why did Rhamphorhynchus have a long tail?

The long tail ended in a diamond-shaped flap that may have helped it steer while flying. The tail was stiffened with ligaments to keep it straight.1 2

?Did Rhamphorhynchus have feathers?

It did not have feathers, but it had a fuzzy coat called pycnofibers, which are like simple hairs. These are different from feathers.1

?Where have Rhamphorhynchus fossils been found?

The best fossils come from the Solnhofen limestone in Bavaria, Germany. Fragmentary remains have also been found in England, Tanzania, Spain, and Portugal.1

Léeb: Some people think Rhamphorhynchus was a dinosaur.

Dëgg: Rhamphorhynchus was a pterosaur, a flying reptile, not a dinosaur.1
