Artifact from Tunnel Ravne.
Picked up during archeological excavation in March 2015 by Tatiana Andreeva.
20000-35000 years old? Ravne Culture?

Official archeological book (1) from Bosnian researchers confirms, that there are many paleolithic place in North Bosnia. This is information that I got in Banja Luca recent spring. So, we can guess, that artifacts from paleolithic times can be easily found in some other parts in Bosnia. In the middle of last March I checked few hundreds of stones from Tunnel Ravne, in Visoko. Some of them were highly interesting and I show them to Dr.Osmanagich. My opinion was that they are from early Paleolithic. Some of the stone I will take with me next time to Moscow State University, where I do my PhD in History of Art. Nice to know academic opinion about it.

For very simple dating, without going into details, I show why my suggestion is such.
From the recent book (2013) of Franch scholar J.Clottes, I take picture made in Chauvet Cave. There are some similarities in picturing of animals in Chauvet age, and in my stone from Ravne.
Maybe this stone is about the same age. 20000-35000 y.ago
Because I did not find any examples of artifacts similar that one I am about to discribe,  name it "Ravne culture", or Ravne. Maybe it is local version of Gravette culture in Austria those times?

Chauvet Age, 35.000 - 22.000 y.o.
I checked with black rounds  two heads of birds and one feline or (and) diar.


On Ravne stone I marked bird head and some rodent image.

  We made few  major suggestions.

1. Ravne stone is around 20000-30000 years old (by compatision to similar images in academic book)
2. Ravne stone maybe have some connection  with  number of 27 000 years,  carbon dating of tunnel itself.
3. It is local (was taked from tonnel 20 meters underground infront of author's eyes).

4. There are lower Paleolithic artifacts in Visoko.

There are few enlarged in photoshop images below.

It seems like human image? With eyes up?

1.Scretches, lines that modern people also do before make "main" image.
2.Holes of different sizes.


The head of deer.

Part 2. Technologie of stone cutting.

We will use two microscopes
1. Stereo
2. Medical
Different types of light. So the color of pictures is different.

Two different sizes of holes.
I suggest two sizes of drills used on this part of surface. Tiny dots to the right, bigger drills in the center, and  the biggest hole were  worked two times.

The row of holes.

More complex situation. First the triangle hole was made, around 2 mm deep and wide. Then in the bottom of the hole were drilled three tiny holes.
This is inlay hole. I guess that drilled holes intend to keep some precious part inside.

Inlay hole. Years ago in such holes they put presious stones or drops of metals. In this case bottom of the hole  has metallic dark layer, that can be recognized as parts of metal.

You can see the process of making such a hole.

1. On the edges still there are direct lines, according which the hole was done.
2. Perhaps, first hole was drilled
3. Than extra material was take with sharp thin knife.
4. Afterwards melted gold or silver were poured in the hole.
5. Red paints (red ocher, natural paint commonly used in tha past) was added to outline the image.

Traditional technic of art - painting.
Black paint was among the most easy to get. There is the line under 80x enlargment. Stereomicroscope.

This is sofisticated sculturing method. The stone has few layers of different color. You can see, that master took upper white colored part of stone, to show dark part.
The place of contact of two layers polished. And both surfaces also were touched by tools, the master "evened" them.

Next step in making sculture. Two different in hight layers are divided by wide black line, that looks like black laque (polish).

Now we hear the next questions...

1. There are lots of worked stones. Where are those fine strong tools?
           We are talking about thousands of years. So, drills, some other elaborate parts of the tools  will be first distroyed by fear, water, pressure, time, and so on. So, if we even see those tools  now, we can not recognize them. Stones, made in millions, still here.

2. Does it mean, stone age people used metal? 
               Yes, they knew and used metal.

And metal parts were distroyed?
                Yes, metal easy to distroy. When we talk about 30000 years ago.

3.Is seems to make such fine work they should have microscopes?

a. It is possible, they had a bit better eye sight and other senses.
b. As "microscope" you can use water, for example. It is well known tric.
c. Natural glass, Bergcristall, can be used for magnification.

4. This old  thing, or we call it, artifact has no meaning.  What for so much work?
        My first answer - this is a part of adoration process, so called "votives". Specially made things to thank Gods and Spirits. Such objects would place on altar infront of sacred images.
        Maybe form of spending "extra free time"? Smile.

    5. It means that people in Paleolithic were as developed as us?
       Yes, they have been more developed as we officially recognize now.
       Do we still consider that Paleolitic people looked like that
