A small, Dinosaur bone

or
A small Dinosaur, bone.
The following are microscope photos of three sections of a small piece of Dinosaur bone. The thin section slides were made using a Hi-Tech Diamond flat lap grinding machine.
The first photo is the actual bone segment, approximately 22mm long and 12mm in cross section.
The next three photos are full scans of the three cross section followed by a few selected sections.
I used two microscopes, a Labomed LB-592 Polarizing and a Zeiss Stemi 305edu with a homemade polarizing kit.

Neat looking pictures. 

Is there anything that these thin sections tell us?

Those close up shots of the slices would make awesome wall art if blown up to canvas size.  I used one of the as a background wallpaper for my homepage. Thanks.

Well, it was fun making them.  I was hoping for something a bit more birefringent to make large format prints.
I am discovering thin sections of fossils are not the best subjects for snappy large format prints.
The short story is: I made them, I might as well post them.

That's cool. I was just wondering if the pictures were the objective, or if you were doing something else with the thin sections. :)

I think they look neat.

EDIT: Have you thought about trying to see if they fluoresce, and then take pics?? Just a thought.

"fluoresce" What wonderful idea.
This is what I do with prints I make from slides.  Unfortunately, this collection does not include any fossils.

thin sections cut perpendicular to the bone can show growth patterns...

Thank you.

I am in the process of refining the Dino slides and will post new results shortly.

I tried an experiment on one slide to see if the calcium in the specimen would effervesce when a drop of muriatic acid was placed on the slide.

As you can see from the photo it was a roaring failure. I am thinking I will sell the process to NASA as a way of making perfect circles without going into space.

A refinement on the small dinosaur bone. The thin section slides received further polishing with the 1200 and 2000 grit diamond discs.

Slide 1 is the first cut and polish as seen in the September post.

Slide 2 is the result of polishing down to 45 microns.

Slide 3 is a section viewed at 40x with Plane Polarized light.

Slide 4 is the same section  viewed through Crossed Polars.

Slide 5 is viewed through Crossed Polars and a full wave Lambda filter.
