I found what I think is a large vertebrae in north Jackson county ky. I think the stone looked like marine deposits in the area I found it in. Is this a vertebrae? I think I can make out cortex bone on the edges in some places, artery holes, trabeculae under the cortex and a large area in the center of the bone for a disc. If so what animal did it come from?

Well, I figured I might show what I've been up to, but I am unsure as to where this topic fits, so please do move this thread to a more appropriate forum if this subject is not fit for this one, Admins After my recent trip to Australia to see my fiancè and fellow forum member Ash, I had a fair bit of petrified wood laying around. The picture below only shows a small portion of the amount Ash and I collected, but I decided to take and cut the orange chunk in the left of the photo into slabs. I had just recently learned that the local rock shop in town actually had a "cabbing" machine, and in exchange for a few slices, I could use them for free to make cabochons of my own. So after shaping a few up onto "dop sticks", I did just that! I was rather surprised how different they turned out-how stunning compared to the original inconspicuous chunk of wood they originally came from! I also cabbed a few pieces of dinosaur bone the shop had laying around; you can see the end results in the photos below They're not perfect (I am a beginner), but just thought I would share how something that is often passed over in collecting can turn out stunning if you put a little work in The first single cab photo you see is the first one I ever did, and I have just recently had it wire-wrapped in sterling silver (the last photo). However, the last photo doesn't show the same quality as the first does due to poor lighting. Nonetheless, it's been a fun hobby to keep me occupied during the winter months I hope you enjoyed this brief update!

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. Additional Dinosaur bone images Crossed Polars Stage was rotated 45° Plane light, stereo microscope Same section with the Darkfield stop in place.

I didn't know where to post these wild colors

Just got back from a dig in the Hell Creek formation. Everything from Hadrosaur, ray teeth, champsosaur verts, gar scales, turtle, ceratopsian frill and theropod teeth were in the immediate area of this bone. We will be heading to the lab in the morning to begin prep, but I was just wondering if any of you seasoned experts might have any idea what this is. Everything was pretty jumbled and most of the bone in the area we were digging was pretty degraded (more like coffee grounds), but this was one of the few in decent shape that seemed to be diagnostic. I will post better pics once it is prepped.

Could I have help to I'd this please? Some better pictures.....not polished just water on it.

My wife spotted this on the side of the road as we were leaving White Mound in Nebo Oklahoma. It may be surrounded by shell because it is very brittle and flakes apart. The bone itself is about 15in long and pretty strong. It weighs maybe 10- 15lbs. Any ideas of what it would be? An uncle of mine believes its a jaw bone.h

Ok, i have a dinosaur bone that is hollow. I am wondering whether or not it is a theropod bone or not, as theropods had hollow bones. Can somebody please identify it for me? I found this bone in the Dinosaur Park Formation of southern Alberta, right outside of Dinosaur Provincial Park
