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.
So that’s where I left it. Can I please have my brain back?
I watched it stumble through a press conference yesterday afternoon
Dang - You beat me to the punch line!
Is this one Normal? Or, is it Abby Normal.
Brain and Brain! What is Brain!
No need for words in this case. Pics speak for themselves.
"Dude, wait, whut?"
Former Vice President Joe Biden, the Democrats hope for the White House, said during an interview that when he previously stayed at Walter Reed hospital the nurses would blow in his nose to get him moving. ...”
Here’s what Biden said: ”I had nurses at Walter Reed hospital who would bend down and whisper in my ear, go home and get me pillows. They would…actually breathe in my nostrils to make me move, to get me moving.”
It took a second read before I got it. LOL
Ping to another thread about Joseph Stolen’s first press conference
When you’re not posting clickbait, how about a donation?
An early ping for next month.
This is the FreeRepublic “1 of” Ping List. The FR “1 of” Ping List is comprised of folks who post hit and run clickbait threads and then rarely if ever reply to posts.
“1 of” Ping list members: Your donations are needed during the next FR Fund Raiser. FR members pay for you to post your hit and run threads for free. Your donations are needed to pay back FR members who pay for your free use of FR bandwidth.
Please donate here.
The “1 of” ping list is on my home page.
LOL! We think alike.
This topic, the source of the 'article', and the blogpimp are still a disgrace to FR though.
Nice Star Trek reference. 😉
