Rare Jovashim shows that ancient leaks were not bleeding

A newly described gossip suggests that scientists are at least 200 million years older than before being thought of, and that their early ancestors have eaten food not on blood, but on small sea creatures.

“This is the only physical focus that we have ever found from this group,” said Karma Nanglo, a specialist at the University of California. He supported the dissertation with researchers at the University of Toronto, the University of Sao Paulo, and Ohio State University, which has been published. Parajise.

At about 430 million years of age, the foam contains a large tail fish. This is a feature that is still found in modern lectures. But there is no significant feature in this focus: forward fish that uses many of today’s skin to pierce and bleed.

This absence suggests a very different early lifestyle for a group known as Herodenida, along with the Jiwashi marine. Instead of sucking blood from stars, crawling animals and other rash, the earliest leaks can rotate in the oceans, eat soft bodily inversebrates, or feed their inner fluids.

“Many special machinery is taken to feed in the blood,” said Nanglo. “Anticogolants, mouth parts, and digestive enzymes are complex. It makes more realizing that the initial lectures were swallowing the victim completely or probably drinking inner fluids of small, soft physical marine animals.”

Earlier, scientists believed that leaks had emerged about 150-200 million years ago. This timeline has now been pushed back for at least 200 million years, thanks to a fossil found in Vocysha Biota, Wisconsin is a geological formation that is known to preserve soft tissue animal bodies, which is usually already falling before foslization.

Lake fossil protection is not a small achievement. Leaks have a lack of bones, shells, or eczema that have been easily protected in millions of years. This type of gossip requires abnormal situations, which often include close burial, a low oxygen environment, and abnormal geo chemical conditions.

“A rare animal and just the right environment to fasten it – it’s like killing the lottery twice,” said Nanglo.

Researchers at Ohio State University came to light during a broader study of the vocal site, who is a co -author of the article. Although it was not initially identified, the sample engulfed Nanglo’s eye during the early pandemic years.

He consulted with leak experts, including Daniel D Carley, the central author of the University of Toronto, and the group worked together to confirm its identity. They eventually believed that they would get a jack because of the tail fish and the clean segment of the body, which is just a combination that is found only in leaks.

Today’s latch is found on fresh water, salty water and even on the ground. Their feeding behavior is just as diverse, from predictions to feeding parasitic blood. But their origin has been difficult to understand because soft physical animals rarely leave fossils.

Nanglo, who studies rarely in Fossil records, said it was part of a great effort to detect the early history of complex life and challenge the assumptions about the past.

“We do not know as much as we think we do,” he said. “This article is a reminder that the roots of the trees of life are deep, and we are starting to map them right now.”

Nanglo added, “This is a beautiful model.” And this is telling us something we didn’t expect. “
