Scientists Find 500-Million-Year-Old Fossilized Brain
The discovery of new evidence supports the previous speculation on 520 million-year-old human-old brain systems, provoking thoughts about the nature of brains, life, and intelligence in the cosmos.
Soft, squishy, and delicate; brain and nervous system tissues maybe some of the worst candidates for preservation in the fossil record.
In past years the best examples of the ancient brain and nerve structures have come from creatures trapped and preserved in amber that was a couple of hundred million years old.
But a few years ago paleontologists claimed to have found evidence of brain structures in the fossil of a 520-million-year-old arthropod – a shrimp-like critter. 3-inch, 520-million-year-old fossil of Fuxianhuia protensa.

That one sample was intriguing but not entirely convincing. Now a new study by Ma et al., reported in Current Biology (and a companion paper in Philosophical Transactions) has followed up with 7 more examples, together with lab work illustrating how the fossilization process may have happened in order to create the features seen today.
Biden’s brain?
“a shrimp-like critter”
Biden’s?.................
“Young Frankenstein” one on the funniest movies ever!
Hey, give it back to Joe! He could have used it yesterday.
That fish is more cogent.....................
So that’s where Joe lost it...
He’s in the White House.
Quick, give it back to Biden!
They did do some brain work on him the steely knife may have slipped.
Calling Joe Biden-—White Courtesy Phone, please.
We already knew where it was. It’s sitting in the Oval Office.
The Biden jokes just keep coming!
