KOMPAS.com – Researchers found Archeology Brain horse crab 310 million years. Such fossil findings have not been recorded and discovered.
Report from Live knowledge, Friday (30/7/2021), This discovery is surprising as well as good news for understanding the evolution of this crustacean ancestor.
In a recent statement in the press Geography 26 July 2021 Online, he said Brain image Of endangered species Euprobes Data.
Researchers have found a fossil in Mason Creek, Illinois, where animal soft tissue is completely preserved.

Despite its name, these “crabs” are actually an arachnid closely related to scorpions and spiders, according to the National Wildlife Federation.
Although pomegranate crab fossils are relatively common, according to the researchers, no one knows what the brains of their ancestors looked like in the past.
“This is the first and only evidence for brains in horsetail crab fossils,” said Russell Bignell, a leading author and archaeologist at the University of New England in Maine. Direct science.
“The chances of finding a brain fossil are one in a million or less,” he added.
In fact, says Bicknell, the soft tissues that make up the brain are particularly susceptible to rapid degeneration.
“For the brain to be protected, it requires very special geological conditions or amber.”
Process Geography Euprop has helped keep Dane’s soft tissues in good condition for millions of years, including his brain.
“Because of that, we’re not really looking at a concrete brain,” Bignell said.
The sediment at Mason Creek is made of a carbonated iron ore called ciderite, which forms concretions – mineral sediments – that can quickly encase corpses and bury them.
Experts have found brain fossils of the 310-million-year-old Euphraps Dane pony crab. Nature has helped preserve these fossils completely for hundreds of millions of years.
Although the concrete protects the horse crab’s body, its brain tissue dies and eventually disappears.
However, as the brain decomposes, it is replaced by a clay mineral called kaolin, which forms the mold of the brain.
Cavolite is white, while ciderite is dark gray.
“This color difference means that the brain fossil stands out more than conventional fossil remains,” Bignell said.
The hunt is now for the most ancient brains that have been fossilized under the unique geological conditions that preserved these pony crabs.
“Mason Creek’s deposit is incredible,” Bignell said. “If we start looking, we might be lucky to find more (brain fossils).”

This discovery offers researchers a unique opportunity to study how arachnid brains evolved over time.
But to the researchers’ surprise, they found that the ancient brains of the Carboniferous (359 million to 299 million years ago) were very similar to those of modern pony crabs.
“Despite 300 million years of evolution, the horsetail crab brain fossil is nearly identical to its modern form,” Bignell said.
