Perfectly preserved 310-million-year-old fossilized brain found
Live Science ^ | Harry Baker

Posted on 07/31/2021 10:17:36 AM PDT by BenLurkin

Soft tissues that make up brains are very prone to rapid decay, Bicknell said. "In order for them to be preserved, either very special geological conditions, or amber, are needed."

In this case, geology helped to keep the soft tissue in tip-top condition over the years and preserve the brain — or at least a copy of the brain. "We have a mold of the brain, not the brain itself, so to speak," Bicknell said.

The deposits at Mazon Creek are made of an iron carbonate mineral called siderite, which forms concretions — mineral precipitations — that can quickly encase a dead body and fossilize it. Although such concretions preserved the horseshoe crab's body, the brain tissue still decomposed and eventually disappeared. However, as the brain rotted away it was replaced by a clay mineral called kaolinite, which created a cast of the brain.

Kaolite is white in color, whereas siderite is dark gray. This color contrast meant the brain fossil "stood out more than it would have normally" from the rest of the fossil, Bicknell said.

The hunt is now on for more ancient brains that might have been fossilized in the unique geological conditions that preserved this horseshoe crab.

“Over 300 million years old but remarkably similar to current horseshoe crab brains. Another straw on the camels back of evolution.”

Not this time.

The horseshoe crab fossils can be found earlier than that. They are a very old species. They are not really crabs at all, more like shelled, sea spiders

I am not a naturalistic evolution guy and always like to twist the godless scientist nose, you can’t this time. Unlike the coelacanth, these are not index fossils.

Before I even clicked on this thread I was certain that would be the first reply. Excuse me, the first correct reply.

perfectly preserved and fossilized are mutually exclusive conditions ...

My thoughts exactly. Who the hell writes that kind of nonsense?

I doubt it is Biden’s, but it could be Hank ‘Guam will flip over’ Johnson’s or Maxine’s... 🤓

LOL! Or maybe your 83 yr old mom looks like she’s 67, so it’s a compliment. All depends on how you view it!

Could be, she was singing karaoke and making CD’s into her 70’s.

At least my doctor tells me that I look better in person than I do on paper.

Did Biden try to sniff it and say it might have looked great at one time?

Fine, Darwin’s theory of natural selection is only a theory, and science may one day disprove it.

But that doesn’t make your superstitious belief in creationism any less far-fetched.

Your remark is analogous to the hoary old "If we are descended from apes, why are there still apes?" objection.

Pitiful!
