Cryptoclidus eurymerus lived in South America and North America and also France, Russia and England. Its fossils have been found in various countries. The plesiosaur eurymerus was originally described as a hindlimb-less animal. Cryptoclidus is a genus that refers to the hidden collarbone. It's located in the shoulder girdle. Cryptoclidus has a robust head and teeth, and it seemed to have developed a taste for soft-bodied prey. Its nasal openings are well-suited to detecting chemical traces and odors in the water. Cryptoclidus was not a complete marine creature. It spent most of its time on land. Also, it probably didn't have time to feed.

An interesting cryptoclidus fact is that they had a seal-like body type. They were small soft bodied animals that existed 66 millions years ago. They belonged to the middle Jurassic age. The diet of small soft bodied animal consisted of small fish, and meat as they had great strong teeth and were carnivores. It was able to carry itself on land using its body plan. Critics of the plesiosaurs hypothesis also argued that air-breathing animals could not survive in cold lakes. The monster is also believed to have been formed 10,000 years ago. In 2003, a group of tourists discovered fossilized vertebrae of this animal on the shores of Scotland's Loch Ness. It was later confirmed that the creatures were not planted.

How do they reproduce?

Studies made with the cryptoclidus reproduction made us widely believe that plesiosaurs were capable of reproduction. This conclusion coincides with the discovery of a fossil that was viviparous. Evidence for this claim is based on the discovery of plesiosaurs that practiced viviparity. Also, the preserved embryos of the nothosaurosaurus lari indicate that this animal behaved similarly. There is also no direct evidence that the cryptoclidus had parents or social living arrangements. However, research says there are some hints that these animals might have lived together in shallow coastal waters. Other animals that give birth to large babies are usually cared for by extended families.

Paleontologist Kevin O’Keefe of the University of Massachusetts says that the discovery of a large, single fetus through fossils was a surprise. The fact that similar embryos has been found in plesiosaurs was first claimed by Harry Govier Seeley. It was estimated that females gave birth to a child that measured about 13.1 ft (4 m) long.

What is their conservation status?

The C. eurymerus is currently extinct. In 1977, the discovery of a floating body with a long neck and protruding flippers caught the attention of Japanese scientists.

Although the extinction of plesiosaurs was not considered a serious scientific issue, their sightings have sparked interest among these strange creatures.

Cryptoclidus Fun Facts

What do cryptoclidus look like?

Major groups of plesiosaurs are distinguished by their head and neck size. Some of these include the cryptoclididae, the elasmosauridae, and the pliosauridae. The classification of these animals can be made from the fact that they had a long neck and may have been bottom-feeders in shallow waters. The typical plesiosaur has a broad body and a short tail. It retained its two pairs of clawed limbs. These animals had four paddle-shaped flippers. It's believed that they used these limbs to propel themselves through the water by performing various movements. They did not have a tail fin. Cryptoclidus was an aquatic reptile that had flexible and curved teeth and a large cryptoclidus skull. They do not have legs or feet, since they mostly live underwater, which is why they have developed fin like flaps to help them swim.

These extinct animals were known to have dark gray and slimy body.

Cryptoclidus species was initially described as Plesiosaurus by Phillips in 1871, it was mistaken or misidentified by him. The plesiosaur eurymerus was originally described as a hindlimb-less species by him. And later cryptoclidus was named by him.

One of the interesting cryptoclidus facts was that these species had peculiar nasal openings just like the terrestrial animals for the respiration.

What are cryptoclidus related to?

Plesiosaurs were large marine reptiles that did not have living relatives. They had long tails and broad bodies. They resided in the Western Interior Seaway during the Cretaceous period. A study conducted by paleontologists Luis Chiappe and John O’Keefe suggested that some Cryptoclidus gave up to 40% of their body length to give birth to live young. The new study focused on the development of bone in plesiosaurs by taking samples from their mothers and babies. These are related to the plesiosaur according to the head and teeth. The head and teeth of the fossils confirm the common characteristics.
