Ohh I got you but to check plain bone glows white to yellow right? But since its fossilized bone its differnt right? I realized fossilized wood could be differnt like you said. Well I guess that wont help but it taught me something.

You're right as long as the mineral content has not been changed.   Since we've gotten onto the subject, you might enjoy this article from the National Park Service on the use of ultraviolet light in museums.

I'm going to be glad when someone figures out what Sasha has (but I'm enjoying the learning that goes with figuring it out)

Yeah I was right about the wood and right about the bone except for the fact that fossilized bone isnt the same as regular bone, and if the mineral content has been changed its being fosilized so not bone so  still right. I was actually planing to get a UV light to take out at night to go a hunting.

Just my $.02, but that top center piece looks opalized, and all of the other pieces (with exception to the metals) appear to be a low grade opal as well. I would do some research into the geology of the area.

Peace

So unless there was an outcropping of older material, that would rule out dinosaurs but not large mammals.

bbwfw, UV fluorescing minerals are cool. No museum collection is complete without one. When I was a kid my dad rigged up a portable short wave UV light and we went fossil collecting in the phosphate mines around Bartow Florida. These mines are full of woolly mammoth and saber tooth tiger bones which fluoresce a bright yellow due to the uranium content under short wave light. we came home with an orange crate full of tusks and teeth. The best collection of hard rock minerals I've seen is at the Montana Tech formerly Montana school of mines in Butte. second best was in Asheville NC. museum down town. Both are worth the trip...I read the biography of Nicoli Tesla the other day. He was the inventor of the fluorescent lamp. The mercury arc lamp had already been invented(1890's) but it put peoples eyes out and gave them such a bad sun burn it was of little use except as a novelty for "black Light" shows where people would dress up in florescent fabrics and dance around on stage wearing all sorts of jewelry made from florescent objects. Tesla who was a smart guy saw that if you put the florescent material inside the bulb with the mercury vapor you had a white light source!!! Most great inventions were nothing more than connecting the dots.

Hi, Carcusrex. I found geological information of the near-Yerevan region. Different  stratums are opened there at different altitudes. The age of outcroppings varied from the upper senon up to paleogene include paleocene, eocene and oligocene.

Hi, Gambol. It is very interesting:  arrowheads from agatized coral! I found here only arrowheads made of obsidian, because native Armenians used this common and proper stone for arrowheads.

Hi,  Seanengman. I think you are right. The content of stones is opal and chalcedony. Sometimes name may be ?opalised wood?,  once in a while ? ?agatized wood?.

Hi, BitburgAggie_7377. May be You are right, but in the senon age stratum, a big  pangolins lived too. The polished structure of a samples the same like in the:

Hi, Bbwfw. Here is photo of the same samples in day light, without  flash-light.

Gambol, hunting with short wave UV, it?s cool!  I?ll surely attempt to find a shark?s tooth, described in region geology and  that I till not found.

Thanks all for replays. Good finds!
