Close examination of these two photos reveals very little movement to replace the gyri into their proper positions.
This is also revealing of how symmetrical this specimen is.

Retouched Photo
Compression that was apparent hand hold. This is extremely more apparent with firsthand visual inspection. Even finger impressions show, but they don't in these images.
botryoidal hematite, (iron ore)
The petrified brain is silica, perfect lithification material.
Iron ore does not lithify into fossils
Geodes...No similarity.
No calcite outer crustation, no "clinging to the walls", No apparent inner striations, according to x-rays and cat scans.
No symmetry in geodes.

Item marked "A" is indicative of midline shift of cirgulate gyrus
Item marked "B" is indicative of geologic "Vug" or biologically, maggot burrough.
Just a couple of dozen left / right symmetries, internally. Follow closely, you should be able to pick up on many others. The image below, allows a fresh look to help identify these symmetries.
Geologists confirm, rocks do not have bilateral symmetry.

The fact is, the only asymmetry is at apparent wound areas and maggot chamber

This specimen even has sulphur at the bullet wound entrance, as well as sulphur spatter surrounding the area.
This x-ray is extra wide for viewing identification. Please scroll right and left as you continue down.
Let's pretend for a moment this petrified brain is actually a geode.
First, note the thickness of the outer crustation.
Also note, the variation of the thickness of the crustation.
This crustation is limestone,( calcitic)
It is very rough in appearance and actual texture.
Inside, you see macrocrystalization,
tightly clinging to the outer wall, or either just formed this way and somehow incurring the outer calcite crustation.
Note the total lack of symmetry, except to view the entire innermost is for whatever reason, botryoidal.
Note, a few very small vugs, mostly in the crust.
The inner material appears to be a form of silica.
This particular geode does not appear to have striation bands.
It also does not have spikes or towers, although some do.
Most importantly, it does not appear to have any bio signs.
Of those signs, one might expect to find symmetry, resemblanse, visual signs of biological fluid motility, external resemblance.
Match up number on left with number on right.
Check similarity.
I have ample reason to believe the internal coloration of this fossil is opaque to transluscent, almost clear as glass, but in some type of chalcedonic cryptocrystalline form...maybe "clear" quartz
The internal structures of this brain were replaced by colored, more dense mineral, possibly various chalcedonys.These probably appear to be suspended within the clear areas.
What's the difference?
Both are botryoidal and both are speroidal.
That is where the similarity stops.
The images on the right are iron ore,(hematite)
Hematite is metal, not mineral.
Metals are not used in fossilization, minerals are.
There is no congruity, no symmetry to the iron ore bubble.
There is no biogenicity, not even vague similarity.
With the brain, petrification minerals are ideal.
Every fissure, lobe, sulchi, gyri, are where they should be, with normal compression allowed, as seen internally and externally.
Bilateral symmetry is defined as the near mirror reflection left and right along a sagittal plane. That would be as if the body were cut in half front to back, head to toe. No other symmetry is expected, but this is expected of all animals and humans This type symmetry not only is not expected of any rocks, but is considered impossible.
Humans belong to the group "Bilateria". Bilateral symmetry permits streamlining, promotes actively moving organisms, favors the formation of a central nervous system and what as an evolutionary term would be referred to as cephalization.
Very important: If you do a study on bilateral symmetry rocks, the only information you will get, is fossils...only fossils!
It is impossible for this to be anything but a fossil because among other reasons, bilateral symmetry, no more than 1 degree off center, with every feature going the correct direction.
