Dolphins had Jurassic-Era reptiles in their hearts and cold blood

Ichthyosaurs and dolphins are the archetypal actions of convergent evolution, which is why the species with two closely related species are equally identical. It suggests a new discovery of fossil Ictyosaur that was more than we liked Jurassic's creatures, hot blood, honey and similar camouflage.

Between 180 million fossil years, the species found in the southwestern position of Posidonia Shale in Germany Stenopterygius ichthyosaur, the best evidence is still given, ichthyosaurs – ancient, dolphin-like reptiles – were hot-blooded creatures.

The new fossil surveillance is so good, said Johan Lindg, a leading researcher at the Swedish University of Lund, who could see animal skin and slippery skin. In addition, he and his colleagues were able to detect internal organs and, molecularly, traces of cell layers within fossil fuels. Today, it is the first example of fossil-fossil-fossil cytokine in scientific literature, indicating ichthyosaurs as heat-blooded or endothermic organisms.

Ichthyosaurs were dinosaurs today, but modern-day whales were very similar in appearance, especially dolphins. Scientists have alleged ichthyosaurs could be hot blood, calculated by their speed of swimming, but this new discovery, according to data published today by Nature, is the first to prove the fossil fossil fossils through fossil tissues.

In modern blue cloths, it is a lubricant, as well as an insulating anti-cold layer, it also serves as a flotation aid and fatty acid store. Cold ice cream, which usually resides in hot climates, does not really need.

"Its main function is isolation," explained Lindgren Gizmodo"Therefore, it is not necessary to have no animals in cold blood. That said, leatherback turtle skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin skin [areas]. "

But unlike the sea turtles, they placed eggs on the beach, ichthyosaurs began to be born, linked to cold blood, according to Lindgren.

In fossil analysis, Lindgren and his colleagues applied a multidisciplinary experimental approach to study the structure and chemistry of conservation aspects. The researchers identified similar cell-like microorganisms, pigments on the animal's skin and traces of internal organs, including the liver.

"We also showed that the skin's interior was full of pimples, that ichthyosaurs were cold blood," said Lindgren. "Fossils are well-preserved, we are able to distinguish between biochemical origin cells, cell organs and traces".

Which added: "Our analysis revealed that the ichthyosaurus was counted, that is, the upper surface of the dark and the abdominal clearness."

Also, dolphins are smuggling as they are camouflaged. In the case of Ithyosaurs, protecting the camouflaged protection from these faces, like pterosaurs of the lower air or aquatic pliosaurs, speculate that researchers.

Lindgren told his team that "he had done the deepest and deepest research ever made on fossil tissues," but he admitted that he was based on a single individual's analysis. Future research "should be extended to other species," he said.

The good news is that this is possible. Ichthyosaur fossils are very common, so paleontologists can find more fossils as pristine as this.
