Scientists find heart to turn 400 million years old, big reveal Ancient heart was in mouth

Scientists found a heart to complete 4 million years: Oldest heart: Scientists have uncovered a major mystery regarding the origin of life on Earth. Researchers have found a heart that is 38 million years old. Scientists have found this heart in three dimensions, called planoderm in fish. Scientists have found that this is the beginning of the appearance of the heart, which was in the mouth of the fish.

You’ll find some of the best-preserved ancient rock formations in the world, from the Kimberley region of Western Australia to the Limerace Range near the town of Fitzroy Crossing. p. There are numerous remains of the age of Baba Adam marine animals, including coderms. This class of fish represents our earliest jawed ancestors. Plasoderms ruled ancient seas, rivers and lakes. It was the most abundant and diverse fish of the Devonian period (41-35 million years ago), but later became extinct.

The study of plasmoderms is important because they provide an opportunity to investigate the history of the origin of the anatomical structure of the jaw. For example, pycoderms are seen when first attached to jaws, teeth, skull bones and organs. This shows the origin of internal fertilization in our vertebrates (vertebrates).

In a paper published in the journal ‘Science’, researchers describe the oldest three-dimensional (3D) heart preserved from a vertebrate, and in this case a jaw apex. The heart of a planoderm is about 38 million years old.

How to find fish

The first fish fossils were found near Fitzroy Crossing in the 1940s from Gogo Station. But they didn’t appear until the 1960s when beautiful 3D preservation technology became available. Using this technique,

Rocks are removed from the bones using mild acetic acid. This technique is like walking on a double-edged sword because it eliminates the soft tissue of the fossil. For the first time in 2000, muscle fragments were found in a plasmoderm fossil.

After this, X-ray methods were used and in 2010, Gogo Punocoderm was identified and muscles including neck and abdominal muscles were revealed.

Using this technique, the researchers were the first to show that the liver, stomach and intestines were present in pigeon fish.

heart in mouth

The most interesting discovery of the researchers is the heart. He identified the first heart of a planoderm using X-ray technology. Then find another heart in a different sample using neutron imaging technology. Life must have been difficult as Punocoderm had its heart in its mouth. At that time, the neck of vertebrates is so short that the heart is behind the throat and below the gall bladder.

Today, 99 percent of vertebrates live in bodies. This suggests that in mandibular vertebrates, further relationships move the lever associated with changes in jaw and neck structure. But this heart transfer will leave a space for lung development.
