O nome significa: “long-nosed face”1
Comía: CarnePlesiosaurosCretáceo SuperiorTecnicamente non é un dinosauro

Dolichorhynchops was a small, fast-swimming marine reptile that lived in the Late Cretaceous seas. It had a long snout and a short neck, and it used its four flippers to chase after fish and squid.1

Dato curioso: este réptil mariño nadaba mentres os dinosauros camiñaban por terra. Todo o mundo lles chama dinos, pero eran outra rama dos réptiles.

Datos curiosos

1

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

2

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

3

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

4

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

5

Scientists used to think some larger specimens were a different species, but now they are placed in a separate genus called Martinectes.12

6

A 2023 study moved two other former Dolichorhynchops species into new genera: Martinectes and Scalamagnus.12

As preguntas máis frecuentes sobre Dolichorhynchops

?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).13

?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.43

?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.14

?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?
