Dolichorhynchops was a plesiosaur, but unlike the long-necked plesiosaurs, it had a short neck and a big head.1

The first fossil of Dolichorhynchops was found by a teenager, George Fryer Sternberg, in Kansas around 1900.1

Its name means 'long-nosed face' because of its long, narrow snout.1

Dolichorhynchops lived in the Western Interior Seaway, a shallow sea that split North America in two during the Cretaceous.1

Scientists used to think some larger specimens were a different species, but now they are placed in a separate genus called Martinectes.1 2

A 2023 study moved two other former Dolichorhynchops species into new genera: Martinectes and Scalamagnus.1 2

?How big was Dolichorhynchops?

Dolichorhynchops was a relatively small plesiosaur, measuring around 3 metres (9.8 ft) long. Some estimates range from 2.5 to 3 metres (8.2 to 9.8 ft).1 3

?What did Dolichorhynchops eat?

It ate fish and squid. Its long, narrow jaws were filled with sharp teeth to grab prey, which it swallowed whole.4 3

?Was Dolichorhynchops a dinosaur?

No, it was a marine reptile called a plesiosaur, not a dinosaur. It lived in the seas during the Late Cretaceous.1 4

?When did Dolichorhynchops live?

It lived during the Late Cretaceous, about 87 to 72 million years ago. Fossils are found in North America.1

?Could Dolichorhynchops swim fast?

Yes, it was a quick and agile swimmer. It used its long, paddle-like flippers to 'fly' through the water like a penguin.4

?Did Dolichorhynchops give birth to live young?

Yes, fossils have been found with unborn babies inside, strong evidence that it gave birth to live young.4
