The giant tooth of the giant ichthyosaur indicates the powerful bite of marine creatures

The remains of a large sea creature with huge teeth that could help hunt giant octopuses have been found in the Swiss Alps.

Ichthyosaurs are large marine creatures in the form of reptiles. It first appeared after the end of the Permian Destruction, also known as the “Great Death”. This happened about 250 million years ago and destroyed two-thirds of the Earth and 96% of marine life.

It is one of three giant ichthyosaurs found in the Swiss Alps and is believed to have lived in the late Triassic period 205 million years ago – spawning some of the last giants.

The team said the findings helped solve the mystery of whether giant ichthyosaurs, like some small creatures, had teeth.

“This is very scant evidence,” said Martin Sander, a professor at the University of Bonn who co-authored the study.

“We thought for a while that they had teeth. Then we thought, ‘We’ve never seen teeth. Now we have a giant tooth and a giant tooth. So some of them have teeth.'”

Writing in the Journal of Vertebrate Paleontology, the team describes how the fossils of three giant ichthyosaurs were discovered at different sites during the formation of Cousin between 1976 and 1990.

The fossil of one of the animals is an incomplete tooth about 10 cm long. The team found that a large portion of the spine and rib were attached to another. The third fossil consists of seven large vertebrae. Sander said none of the remains appeared to belong to a known lineage of ichthyosaurs.

The tooth, which lacks much of its crown, is the second time a giant ichthyosaur has come in, and the group says it’s the largest ever for such an organism, with more than one species. HimalayasIt was discovered in China and it is believed that its body length is about 15 meters.

“Ichthyosaurs have a very distinct tooth structure that can be seen at the root and crown,” Sander said, adding that the giant-toothed alpine creature may have eaten small ichthyosaurs and giant squid.

Sander said one of the creatures was the same size HimalayasThe other two, including the tooth monster, looked like giant ichthyosaurs. sastasaras, a creature previously found in British Columbia that is about 21 meters long – two lengths of a double-decker bus. “This skeleton had vertebrae of the same diameter as the Alpine ones,” Sander said.

But she was not the largest igtes known to have lived. Among other discoveries, the toothless jaw found in the Bristol Canal is believed to belong to an ichthyosaur, which measured about 26 meters in length.

While Igdosers roamed the oceans, the newly reported remains were placed in a pond, indicating that the animals had entered the shallow waters. “A similar problem occurs when you catch a sperm whale in the North Sea,” Sander said.

doctor. Ben Moon, a University of Bristol archaeologist who was not involved in the work, said the creatures may have entered shallow waters to mate or give birth. He said the new report is exciting because fossils of giant ichthyosaurs are rare.

doctor. It has been difficult to determine the size of a giant ichthyosaur based on a single tooth, said Nick Fraser, a former researcher at the National Museums of Scotland, but these findings shed new light on reptiles.

“Until now we suspected that most of the larger ichthyosaurs were toothless and sucking,” he said, adding that the newly reported tooth size is surprising.

“The owner of this tooth should not be confused,” Fraser said. “Along with the remains and ribs of vertebrates, in the past, Triassic waters provided shelter for some really huge marine reptiles that were probably the size of living blue whales, and there is conclusive evidence that some of them had large jaws armed with teeth.”
