520-million-year-old terrorizing sea creatures had 18 tentacles to kill their prey

In China, the fossil of a 520-million-year-old sea dweller with 1

8 tentacles was discovered, a discovery that has amazed researchers.

The incredible find known as Daihua Sanqiong was, in the opinion of the scientists who dug it up, a distant relative to honeycomb jelly.

"When I saw the fossil for the first time, I immediately noticed some of the features I had seen in honeycomb gels," said Dr Jakob Vinther, a molecular paleobiologist, in a statement: "You could see these repeated dark spots along each tentacle see that resemble the comb jelly comb fossilization. The fossil also preserves rows of cilia, which can be seen because they are huge tree of life, such large ciliary structures are found only in Kammgelees.


Also, Vither told The News Agency The discovery of the ancient sea monster is a big deal because it was perhaps one of the first Animals that evolved on the earth.

Casey Dunn, professor of ecology and evolutionary biology at Yale University, however, questioned the results. In an interview with Live Science, he said he was "very skeptical of the conclusions they draw." Dunn was not involved in the study. The 18 tentacles contained "fine feathery branches with rows of large ciliary hairs" that were used to help the creature find prey, Daihua added.

more tentacles than modern octopuses, but it is not the only ancient creature that has so many arms. Dinomischus, a living creature that lived 508 million years ago, also had 18 tentacles and an organic skeleton.

"We also realized that a fossil, Xianguangia, which we thought was a sea anemone, is actually part of the comb jelly branch. Said co-author Prof. Cong Peiyun in the statement.

In the study, the researchers demonstrate how the comb gels have developed. They describe the organic skeleton that existed during the Cambrian period, as well as the honeycombs that developed from the tentacles and other evolutionary changes.

"I think with such body transformations we have some answers to understand why Kammgelees are so difficult to understand," co-author Dr. Luke Parry added. "It explains why they have it. So many genes have lost and possess a morphology that we see in other animals."
