The chef feathered fossils reveal the strength of the preserved volcanoes

The fossilized feathers that were discovered 136 years ago are still revealing new secrets. The researchers found that the volcanic rocks that maintain the feather carries a microscopic details reserved inside the fossil.

Team Research –Published Today in geology – a link that feathers are preserved in zeolite, a way to preserve that has not been reported for soft tissues yet.

“The fossil feathers are usually preserved in the old rock materials placed in lakes or lakes,” said Valentina Rossi, a researcher at the University of College Cork and the author of the study. Release. “The eagle of the fossils is preserved in the ash deposits, which is very unusual.

Rossi Gizmodo told an email that the result “expands in what is possible in the fossil record”, and that low temperature flows of volcanoes are “very good media to maintain soft tissues.”

Soft deposits in the bottoms of water bodies-for this issue, can cover the non-solid earth, such as clay collapses-dead living organisms, which prevents them from wiping and Maintain their remains Deep time. But preserving zeolite- the minerals rich in silicon and silicon, which are common in volcanic environments- a new result, can mean fossils that are more preserved in a volcano below the line.

The feather belongs to an eagle who lived in Italy about 30,000 years ago. The animal’s body was completely preserved in three dimensions, from the bird’s eyelids to the ends of its wings. Ergo: Fear fossil that is preserved to microscopic pigment structures in the Al -Hafori wing.

“We are used to (thinking) that volcanic deposits are linked to fast -moving hot packages that will destroy the soft tissues,” said Daid Eurino, study coordinator and researcher at the University of Milan, in the same edition. “However, these geological settings are complex and can include low temperature deposits that can maintain soft tissues at the cellular level.”

In fact, the volatile and advanced conditions of volcanic eruptions are amazingly good in maintaining the most sensitive tissues, in appropriate conditions. Last month, a team of researchers confirmed that the eruption of Jabal Fisovos in Italy in 79, which destroyed and burying the city of Pompei The brain in the glassKeep the microscopic axes and neurons in a solid condition.

Volcanoes arise from hot gas and ash, and of course lava when they break out, and they often have deadly effects of life in their direct vicinity. The nature of the eagle preservation is a brand that the most conservative fossils may fall into awaiting the discovery of irrigation specialists.
