Jurassic sturgeon fin cut and polished

[LiamL]

Ever wondered what a sturgeon fin looks like cut down the middle and polished?

 

This is from a large fish called Gyrosteus mirabilis that swam in the seas near whitby all them years ago.

 

i think it’s the cartilage.

 

As found

 

 

Cut straight down the middle, showing the pyrite too.

Very cool! I love interesting slices.

Great fossil!  

 

You've made it that much more interesting with the cut and polish. 

Nice job!

Stunned by the detail and colors! I wasn't expecting that after looking at the before photo.

Interesting How do you even find this stuff?

@LiamL,

Sure, do you want to see the polished middle from above or the outside?

[Fossildude19]

Both, please!
