First-Ever Dinosaur Brain Tissue Found Preserved In a Pebble (sciencemag.org)
sciencehabit quotes a report from Science Magazine: A decade ago, a fossil hunter was combing the beach in southeastern England when he found a strange, brown pebble. The surface of it caught his eye: It was smooth and strangely undulating, and also slightly crinkly in some places. That oddly textured pebble, scientists report today, is actually an endocast -- an impression preserved in the rock -- that represents the first known evidence of fossilized brain tissue of a dinosaur (likely a close relative of Iguanodon, a large, herbivorous type of dinosaur that lived about 133 million years ago). Human brains and bird brains are packed tightly into the brain case, so that their convolutions leave an impression of the inside of the case. But dinosaur (and reptile) brains are more loosely fitted; they are surrounded within the brain case by membranes called meninges, tough sheaths that protect and support the brain. So an endocast of a dinosaur brain might be expected to show those structures -- and it did. But beneath them, remineralized in calcium phosphate, the researchers also spied a pattern of tiny capillaries and other cortical tissues -- the sort of fabric you'd expect for the cortex of a brain. That those textures were pressed up against the brain case doesn't necessarily mean that dinosaurs were bigger-brained and smarter than we thought, however: Instead, the dinosaur had likely simply toppled over and been preserved upside down, its brain tissue preserved by surrounding acidic, low-oxygen waters that pickled and hardened the membranes and tissues, providing a template for mineralization. The structure of the brain, studied with scanning electron microscopes, reveal similarities to both birds and crocodiles. The researchers reported their findings in a Special Publication of the Geological Society of London.
it was larger than any slashdot editor's brain.
-linux... they can't *give* that shit away.

Best comeback line ever.
If you think I voted for Trump because of this post, you're wrong. I voted for Dr. Jill Stein of the Green Party. Again.
Was a dino's brain in a pebble or was it a pebble inside the dino's brain?! Inquiring minds want to know!
So those smartwatches are useful for something.
First recognised..
I have also found lumps that have looked very similar to this one,but have been told that they were nothing of interest.
I thought they looked like brain also,but was told they were just natural minerslisation and normal geological formations.
I lived in Hythe bay area for 15+ years,used to explore beaches all the way down to Dorset,stuff from Hezbollah will eventually arrive in Hythe bay and its beaches because long shore drift is mostly from west to east in the English channel.
There is a very high chance that this type of material has Bern found on multiple occasions,and possibly already exists in collections,now that it's accepted it does happen and others know what I look for,many many examples will rapidly turn up...
Pity I don't have my collections still,I put mine back on the beach at low tide one night when I knew I was leaving the area...
Was there an orange toupee with it?

I think the authors of the Bible would strongly disagree.

So humans do not have meninges? TFA is a complete disaster

That's no dino brain. Two decades ago I had a hobby of breeding pet rocks. I got a little carried away and one thing lead to another, and the rocks eventually got smarter. Once I realized my mistake, I pulverized all of them and tossed their powered remains into the ocean. It appears I hadn't dusted them as much as I thought.
Please everyone, make sure the next beach you visit is still sandy. We must not let them gain a single beachhead. People were afraid of a super intelligent AI taking over the world, but it's the stupid rocks who have had enough of everyone walking all over them!
Misleading title.
"Fossilized" does not mean tissue was preserved, it means it was replaced.
Dumbing down science is stupid.
but check the meninges wiki and you can find information concerning the human variety.
Small wonder that they died out with a pebble-sized brain.

Good thing human brains don't have a meninges, otherwise we could get meningitis! Oh, wait.....
I browse on +1 so AC's need not respond, I won't see it.
is the bite taken out of the brain thus proving the long-dismissed hypothesis of dinosaur zombies.

"First-Ever Dinosaur Brain Tissue Found Preserved In a Pebble". I mean, really.
