Question 1

How do you say Rhamphorhynchus?

Accepted Answer

You say it RAM-foh-RINK-us. Break it into four parts: RAM, foh, RINK, and us. The tricky part is the middle, where the letters look scarier than they sound. Say it slowly a few times and it gets easy fast. Once you can say it, you will want to say it all the time because it sounds amazing.

Question 2

What does Rhamphorhynchus mean?

Accepted Answer

The name comes from two Ancient Greek words meaning beak and snout, so the full name basically means beak-snout. It was named that way because of its long pointed jaws with a sharp toothless tip that looked like a bird's beak. The German scientist Samuel Thomas von Soemmering chose the name in 1825 after studying the fossil. It is a very accurate description because that extraordinary jaw is the first thing anyone notices about this animal.

Question 3

Was Rhamphorhynchus a dinosaur?

Accepted Answer

No, Rhamphorhynchus was not a dinosaur. It was a pterosaur, which is a completely separate group of flying reptiles that evolved independently from dinosaurs. Pterosaurs and dinosaurs were cousins on the reptile family tree, but they split apart very early and developed very differently. Calling Rhamphorhynchus a dinosaur would be like calling a dolphin a shark: they lived in similar environments and looked somewhat similar, but they are not the same kind of animal.

Question 4

How big was Rhamphorhynchus?

Accepted Answer

The largest known Rhamphorhynchus individuals had wingspans of about 1.81 meters, which is roughly 6 feet across, about the wingspan of a large seagull or albatross. Despite that impressive wingspan, they were very lightweight, probably weighing less than a can of soup, because their bones were hollow. Smaller individuals, probably juveniles, had wingspans of only about 30 centimeters. They were built for agility and speed rather than raw size.

Question 5

What did Rhamphorhynchus eat?

Accepted Answer

Rhamphorhynchus was a carnivore that ate mainly fish and cephalopods, the ancient squid-like animals of the Jurassic seas. We know this with unusual certainty because fossils have been found with actual fish bones and cephalopod remains preserved inside the animal's fossilized stomach area. Its needle-like forward-angled teeth were perfectly shaped for gripping slippery fish and not letting them escape. Scientists think it hunted by skimming low over water and plunging its beak in to grab prey.

Question 6

When did Rhamphorhynchus live?

Accepted Answer

Rhamphorhynchus lived during the Late Jurassic period, between about 154.8 million and 143.1 million years ago. That means it existed roughly 80 million years before the mass extinction that wiped out the non-bird dinosaurs. During its time, what is now Europe was a warm archipelago of islands surrounded by shallow tropical seas, which was perfect hunting territory for a fish-eating flier like Rhamphorhynchus.

Question 7

How did Rhamphorhynchus fly?

Accepted Answer

Rhamphorhynchus flew using large wings made of a thin but tough membrane of skin and muscle that stretched from its enormously elongated fourth finger all the way to its hind legs. It had hollow lightweight bones that reduced its body weight dramatically, making flight easier. The diamond-shaped tail vane at the end of its stiff tail helped it steer and stay stable in the air, almost like the tail fin of a paper airplane. Scientists believe it was an active, powered flier rather than a passive glider.

Question 8

Where have Rhamphorhynchus fossils been found?

Accepted Answer

Fossils of Rhamphorhynchus have been found in three main countries: Germany, Portugal, and Tanzania. The most famous and detailed specimens come from the Solnhofen Limestone in Bavaria, Germany, which is world-famous for preserving extremely fine detail including soft tissue like wing membranes and the tail vane. Specimens from the Tendaguru Formation in Tanzania are particularly exciting because that same site also produced giant sauropod dinosaurs. The wide geographic spread shows Rhamphorhynchus was a successful and widespread animal in its time.

Question 9

What is the famous Rhamphorhynchus fossil story?

Accepted Answer

One of the most dramatic fossils ever found shows a Rhamphorhynchus that was caught by a large predatory fish called Aspidorhynchus. The fish apparently snapped at the low-flying pterosaur, caught its wing membrane in its jaws, and then could not release it because the membrane snagged on the teeth. Unable to swim properly, the fish drowned, and both animals sank to the lagoon floor and were preserved together as one extraordinary fossil. It is like a snapshot of a bad day 150 million years ago, frozen in stone forever.

Question 10

Did Rhamphorhynchus have teeth?

Accepted Answer

Yes, Rhamphorhynchus had teeth, but only along most of its jaw, not at the very tip. The front of the jaw ended in a hard, curved, toothless beak-like point, while the rest of the mouth was lined with long needle-like teeth angled forward at a sharp angle. This combination was perfect for catching fish: the teeth would impale the prey and the angle meant slippery fish could not wriggle backward out of the mouth. It is a very different tooth arrangement from meat-eating dinosaurs.

Question 11

Was Rhamphorhynchus related to Pterodactylus?

Accepted Answer

Rhamphorhynchus and Pterodactylus were both pterosaurs and actually lived in the same time period and the same geographic area, but they were only distant cousins within the pterosaur family tree. Rhamphorhynchus belonged to the older rhamphorhynchid group, which had long stiff tails, while Pterodactylus belonged to the more advanced pterodactyloid group, which had much shorter tails. Think of them like crows and seagulls: both birds, both flying near the same coasts, but belonging to different families with different body plans.

Question 12

How do we know what Rhamphorhynchus looked like?

Accepted Answer

We know an extraordinary amount about Rhamphorhynchus thanks to the Solnhofen Limestone of Germany, which preserves soft tissue that normally rots away before fossilization. Paleontologists have found fossils showing the actual wing membrane, the webbing between toes, and the diamond-shaped tail vane in fine detail. These are not guesses or reconstructions: the impressions of the soft tissue itself are visible in the rock. It makes Rhamphorhynchus one of the best-understood pterosaurs in terms of what it actually looked like in life.

Question 13

Could Rhamphorhynchus walk on the ground?

Accepted Answer

Scientists believe Rhamphorhynchus could move on the ground but was probably not graceful about it. Studies of pterosaur trackways and limb anatomy suggest that rhamphorhynchid pterosaurs like Rhamphorhynchus folded their wings against their bodies and walked on all four limbs, using both feet and the knuckles of their folded wings. It was probably an awkward waddle rather than a confident stride. They almost certainly spent as much time airborne or perched on rocks and cliffs as possible, only landing when they had to.
