Living Tissue Fragments Of 350 Million Years Ago
Scientists thought long-lasting complex organic molecules would not be preserved after fossilization. But the 350 million – year – old marine fossils discovered in Ohio – Indiana changed these assumptions.
It has been observed that there are structures of various colors in a fossil of living species known as crinoid. These fossilized creatures were discovered to have organic compounds in their skeletons in different colors.
It is estimated that the living beings of the found fossils are rapidly buried in the sea layers during the carboniferous intense storms that occur in North America and are protected from water in sediments of fine fragments under the soil. It seems that some of the organic molecules trapped in the voids on the living thing could remain intact.
Professor at Ohio University. William Ausich,
“There are a large number of fragmented biological molecules in the rocks all over the place that we call live signs. These belong to plants and animals that lived in ancient times. They are all fragmented and mixed. But inside one of the oldest living traces we found. We can say that these organic molecules remain from the living things we studied their remains. “
These aromatic compounds, called quinones, are used as pigments or act as poisons against hunters
The skeletal remains are the reason why the crinoid are so well preserved. There is a skin layer on the hard calcite (CaCO3) shells, similar to aquariums known as sand dunes. Their long bodies come from thousands of stacked calcite rings, each ring carries a large calcite crystal feature and contains vital cavities. When the crinoid dies, the texture starts to rot, but calcite sinks in the voids. This calcite preserves its stability in the geological period and therefore the organic matter is retained in the rock.
“According to the direction of the crystals, the rock fills the skeleton. For this reason, it is possible to find trapped organic matter in large crystals. “ The next works are to determine what kinon molecules are.
The geochemists Yu-Ping Chin and O’Malley, who are studying, compare the organic molecules that they have obtained from the fossils with the molecules in the lakes of today’s living. Researchers have shown that these molecules resemble each other in their living beings, as well as in their fossilized ancestors.
The fossils between rocks made of inorganic molecules are entirely opposite to the theory of evolution. Now, the fossil is in the same categorical age but organic, so astonishingly that scientists have had the opportunity to examine the living thing of the living thing. In this example, we clearly understand that organisms today are living cells and tissues that are the same as living tissues a hundred years ago. These developments show us once more that the creation of living things is real.
